A New Species

Aristida surperuanensis sp. nov. is described and illustrated. The new species, from southern Moquegua (Peru), differs from A. flaccida in having contracted panicles, spikelets to 1–1.1 cm long and lemmas 5.5–6.5 mm long. The central awn is straight, ascending, 3–6 mm long and lacking a column, the lateral awns are ascending, 1–2.5 mm long and 1/3 as long as the central awns, and the caryopses are fusiform and 4–4.5 (–6) mm long. A key to the species of Aristida in Peru is included and the conservation status of the new species is evaluated.

A new species of the genus Senecio (Asteraceae, Senecioneae) belonging to S. ser. Suffruticosi subser. Caespitosi is described from the pumices of the Ticsani Volcano, central-eastern part of the Moquegua Department in southern Peru. The new species differs from S. moqueguensis by its longer indumentum, different leaf shape and size, wider involucres, narrower calycular bracts, a greater number of phyllaries per capitula, and shorter pappus. A table with the morphological comparison with other species of Senecio is provided and the conservation status of the new species is assessed.

A New Species

A new species of Epidendrum from southern Peru is described and illustrated. Epidendrum yanatilense is similar to Ecuadorian E. pucunoënse, but differs in the small habit; non-resupinate flowers; small flowers; sepals oblong-lanceolate; petals apex rounded; 3-lobed lip and; two calli, large, laminar, rhomboid, leaning inwards, without mid-rib in the middle. Information on its distribution, habitat, phenology, conservation status, as well as traits that distinguish it from similar species are provided.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Puya colcaensis is described and illustrated as a new species found in the Province of Caylloma (Arequipa) in southern Peru. This species has a compound inflorescence, bluish-green flowers, with pedicels smaller than 1.5 cm, which are exceeded by the floral bracts, and sepals with dense stellate trichomes. It is similar to P. araneosa and P. adscendens.

A New Species

Pariana caxiuanensis (Poaceae) is described and illustrated as a new species from the Brazilian Amazon. The new species is characterized by having the leaves clustered at the apex of the leafy culm, fimbriae few to absent, dimorphic flowering culms, large ligules (2.5–4 mm long), and pubescent to hirsute synflorescences. We present a morphological description, illustrations of the new species, the conservation status assessment, and a key to differentiate P. caxiuanensis from its morphologically related congeners.
