Parrya nauruaq Al-Shehbaz, J. R. Grant, R. Lipkin, D. F. Murray & C. L. Parker (Brassicaceae) is described from the Seward Peninsula of Alaska. It differs from the other North American species in Parrya R. Brown by its smaller flowers and fruits, and by its fewer seeds per fruit. A key to the four North American species of Parrya is provided.

Onosma bisotunensis Attar & Hamzeh'ee (Boraginaceae), a new species from western Iran, is described and illustrated. It is distinguished from its nearest relative, O. hebebulbum DC., by having a pilose (vs. glabrous) nectariferous ring, a bilabiate (vs. regular) calyx with two or three basally connate (vs. free) lobes and larger corolla ca. 19 mm (vs. 15 mm) long and pubescent (vs. densely villous) outside, and anthers 8–8.5 mm (vs. 6–7 mm) long.

Three new species of Davilla Vandelli from Amazonas, Bahia, and Pará states, Brazil, are described and illustrated. Davilla bahiana Aymard resembles D. cuspidulata Martius but mostly differs by its leaves coriaceous, papillate on the upper surface, with lateral nerves 11 to 19, and carpels strigose at the apex. Davilla bilobata Aymard is related to D. grandifolia Moricand but can be distinguished by its tertiary nerves deeply areolate on the lower surface, inflorescence shorter (to ca. 5.5 cm), the shape and pubescence of the sepals, and the petals bilobed. Davilla neei Aymard was collected inside the study plots of the Biological Dynamics of Forest Fragments Project in central Amazonian lowland forest; it is similar to D. kunthii St. Hilaire but differs by its wider leaves (7–)15 cm long, the margins coarsely serrate, short inflorescences (only 10–11 cm long), and carpels densely hispid-incanous. Davilla bilobata is a distinctive species for its bilobed petals in a genus with otherwise predominantly entire petals.

Doliocarpus schultesianus Aymard from moist forests in the upper Río Negro region (Vaupés department) and D. triananus Aymard from montane forests in Antioquia department, Colombia, are described, illustrated, and compared to their closely related species. Doliocarpus schultesianus is not evidently allied to any other Doliocarpus Rolander species; this new species has inflorescences produced from short shoots (brachyblasts) and young fruit completely covered by stinging yellow trichomes. Doliocarpus triananus is most similar to D. pipolyi Aymard due its chartaceous leaves with margins dentate along the blade and its papyraceous basal bracteoles, but it differs from that species in its leaf and sepal shape, dense pubescence along the midrib and secondary nerves on the lower surface, peduncle patent-pilose, and fruit 10–12 mm in diameter, completely covered by white trichomes. An updated key to the 19 species of Doliocarpus from Colombia is provided.

Amaranthus hunzikeri N. Bayón (Amaranthaceae), a new Argentinian species of subgenus Albersia (Kunth) Grenier & Godron from the Andes Mountains at altitudes above 3200 m, is described and illustrated. It resembles A. cardenasianus Hunziker, A. squamulatus (Andersson) B. L. Robinson, and A. urceolatus Bentham, but it differs by the prostrate or decumbent habit, spatulate leaves, and staminate flowers with three to five sepals. A key to the species in Amaranthus L. sect. Pyxidium Moquin-Tandon is included.

A key to the four varieties of I. gordonii is presented, and a lectotype is designated for Horkelia gordonii var. alpicola Rydberg ex Howell.

A recent investigation of Weinmannia L. (Cunoniaceae) material collected from the Yungas region of La Paz, Bolivia, has uncovered two new species, W. davidsonii A. Fuentes & Z. S. Rogers and W. yungasensis A. Fuentes & Z. S. Rogers, both endemic to the area. Weinmannia davidsonii is similar to W. bangii Rusby but differs most obviously by the tomentose (vs. glabrous) ovary and denser pubescence of the leaves. Weinmannia yungasensis is close to W. dryadifolia Moricand ex Seringe but is distinguished most notably by the leaves that are up to 5-foliolate (vs. up to 3-foliolate), the larger simple leaves (0.9–3 × 0.8–2.5 cm vs. 1–2 × 0.6–1.2 cm), the glabrous (vs. pubescent) stipules, and the lax (vs. congested) longer inflorescences ((2–)3.5–5.5 cm vs. 1–3(–3.5) cm). Both species belong to section Weinmannia L.

An evaluation of Asian Brotherella Loeske ex M. Fleischer reveals that a new combination in the genus Heterophyllium (Schimper) Kindberg is necessary to replace B. amblystega (Mitten) Brotherus for its noticeably dimorphic stem and branch leaves, strongly serrate leaf apices, differentiated alar cells in an excavate group, erect and symmetric capsules, and strongly papillose spores. Heterophyllium amblystegum (Mitten) Y. Jia, S. He & Crosby is here validated and lectotypified along with a full description and a key to the Himalayan species of Heterophyllium.

Werauhia noctiflorens T. Krömer, Espejo, López-Ferrari & Acebey (Bromeliaceae), a new species from the states of Chiapas and Veracruz in Mexico and the Toledo District in Belize, is described and illustrated. The new taxon has a simple, secund inflorescence, with white to greenish white flowers, large sepals and petals to 3.3 and 5.5 cm, respectively, and fusiform and rostrate capsules. Werauhia noctiflorens is compared to the similar taxa W. macrochlamys (Mez & Wercklé) J. F. Morales, W. pittieri (Mez) J. R. Grant, and W. vanhyningii (L. B. Smith) J. R. Grant.

Three subspecies of Rosa nutkana C.

Gastrodia wuyishanensis Da M. Li & C. D. Liu (Orchidaceae) from Wuyishan National Nature Reserve in Fujian, China, is described and illustrated. This new species is similar in habit to G. menghaiensis Z. H. Tsi & S. C. Chen, from which it differs by having a rhombic-ovate lip that lacks a long claw at the base and two calli on the upper surface as found in G. menghaiensis.

A new Hawaiian species of the Pacific genus Cyrtandra J. R. Forster & G. Forster, C. wagneri Lorence & Perlman, is described from the island of Hawai‘i. It is unique in its combination of opposite leaves, cauligerous 12- to 25-flowered cymose inflorescences, deeply divided calyx that is actinomorphic, symmetrical in bud, and persistent in fruit, and calyx lobes that are lanceolate to linear-oblong, green, and internally puberulent distally. Due to its restricted distribution, small population size, and vulnerability to threats from feral animals, weeds, and stochastic events, it is considered to be critically endangered (CR) based on IUCN Red List criteria.

Physaria scrotiformis O'Kane (Brassicaceae) is a newly described, diminutive, long-lived perennial from the upper subalpine–lower alpine zone of the San Juan Mountains of southwestern Colorado. The species grows on windswept, nearly barren exposures of Leadville limestone on West Silver Mesa. The species is another example of a taxon bridging the gap between the synonymized genera Lesquerella S. Watson and Physaria (Nuttall ex Torrey & A. Gray) A. Gray s. str. Additionally, the following new combinations and changes in status are made and keys are provided where needed: P. carinata (Rollins) O'Kane & Al-Shehbaz subsp. paysonii (Rollins) O'Kane, P. carinata (Rollins) O'Kane & Al-Shehbaz subsp. pulchella (Rollins) O'Kane, P. didymocarpa (Hooker) A. Gray subsp. lanata (A. Nelson) O'Kane, P. didymocarpa (Hooker) A. Gray subsp. lyrata (C. L. Hitchcock) O'Kane, P. floribunda Rydberg subsp. osterhoutii (Payson) O'Kane, P. geyeri (Hooker) A. Gray subsp. purpurea (Rollins) O'Kane, P. hitchcockii (Munz) O'Kane & Al-Shehbaz subsp. confluens (Maguire & A. H. Holmgren) O'Kane, P. kingii (S. Watson) O'Kane & Al-Shehbaz subsp. kaibabensis (Rollins) O'Kane, P. kingii (S. Watson) O'Kane & Al-Shehbaz subsp. utahensis (Rydberg) O'Kane, P. lepidota Rollins subsp. membranacea (Rollins) O'Kane, P. newberryi A. Gray subsp. yesicola (R. C. Sivinski) O'Kane, and P. saximontana Rollins subsp. dentata (Rollins) O'Kane.

Tillandsia tehuacana I. Ramírez & Carnevali, a new species in the T. utriculata (L.) L. complex (Bromeliaceae) from Puebla, Mexico, is described and illustrated. The new entity is similar to T. makoyana Baker, but the rosettes are cylindrical (vs. funnelform), the leaves are coriaceous (vs. sclerotic), the leaves have a proportionately larger sheath compared with the lamina (vs. leaves with the sheath and lamina subequal), and the rachis of the inflorescence is sharply flexuous (vs. straight). The new species is also characterized by its habit, since it usually grows in dry thorn-scrub-cactus associations, while T. makoyana grows in different vegetation types, including oak and low deciduous forests. The new entity is also similar to T. pinicola I. Ramírez & Carnevali, but the new taxon differs by its larger rosette and inflorescence, its tubular rosette with leaves that are gray and purple and white lepidote on both sides (vs. a funnelform rosette with green leaves and only sparsely white lepidote abaxially), the floral bracts much shorter than the sepals (vs. subequal), the flowers ovate in shape (vs. tubular), and the three stigmatic lobes twisted together (vs. not twisted together).

Mousonnia adpressipilosa D. L. Denham ex Ramírez-Roa (Gesneriaceae), a new solitary-flowered species from southern Mexico and Guatemala, is described and illustrated. It has been collected principally in Chiapas, Mexico, with only one location in the Sierra de los Cuchumatenes, Guatemala. Although the possession of solitary flowers is considered unusual in Moussonia Regel, an increase in the number of species both validly published and undescribed with this condition indicates the opposite. The combination of characteristics that distinguish the new species from other solitary-flowered species are principally the whitish strigose indumentum; the shallowly serrated and revolute leaves; the flat adaxial and abaxial surface of the leaves, adaxial surface green, abaxial surface reddish; and flowers with thick, narrow, slightly ventricose, and gradually widening tubular corollas. A key for the solitary-flowered species of Moussonia is included.

Astragalus hashtrudicus Ranjbar, a single new species endemic to Iran, is described and illustrated. The new species belongs to subgenus Cercidothrix Bunge, section Incani DC., in Astragalus L. and seems to be distinct among the Iranian species. Astragalus hashtrudicus is distributed in northwestern Iran in the Azarbaijan Sharqi province. It is closely related to A. prilipkoanus Grossheim and is distinguished by its pods that are rather densely covered with appressed white trichomes and its leaflets that lack minute dark reddish dots. The conservation status is evaluated as VU (Vulnerable) according to IUCN criteria.

A new species of Habranthus Herbert (Amaryllidaceae) is described and illustrated. Habranthus sanavirone Roitman, J. A. Castillo, G. Tourn & Uria is found in sandy soils of central Argentina. The new species resembles H. robustus Herbert in size but can be easily distinguished by the absence of bulblets, its glaucous leaves, and its recurved light yellow tepals, with this feature not found in any other species of the genus.
