Tripogon uma-ganeshii, a new species of Poaceae from the Horsley hills of Chittoor district of Andhra Pradesh, India, is described and illustrated. The new species is allied to Tripogon tirumalae Chorghe et al., and T. trifidus Munro ex Stapf, in having 2-lobed lemma and median awn longer than the lemma length; but differs from Tripogon tirumalae, in length of leaf blades and spikes, number of florets in spikelets, size of the glumes, lemmas and paleas. It differs from Tripogon trifidus, in height of the culms, nature of leaf sheath, length of leaf blades, number of florets in spikelets and size of the glumes.

Guihaia heterosquama X. Y. Li, a new species from Chongqing, China, is described and illustrated. Guihaia heterosquama is similar to G. grossifibrosa and G. argyrata both in the shape of the leaf blade and flower structure, but it can be easily distinguished by its leaf scales, leaf sheath fibers and hastula. Notably, Guihaia heterosquama differs from all the reported species of Guihaia by the presence of a distinct pistillode in the male flower.

The grass genus Poa L. is widespread throughout temperate areas of the Andes, being a common constituent in the highly diverse but threatened high-elevation páramo grasslands of northwest South America. Knowledge of Poa from these páramo areas is very limited, however, with no comprehensive taxonomic treatments available for Colombia, which contains the largest area of páramo in the Neotropics and its surrounding countries. We present a taxonomic revision of Poa for Colombia accepting 15 species, including two recent combinations of Poa previously circumscribed in Aphanelytrum (Hack.) Hack. We describe a new species, P. colombiana Soreng & Sylvester, and a new variety, P. subspicata (J. Presl) Kunth var. glabrata Soreng & Sylvester, for Colombia and Ecuador. Poa colombiana is similar to P. aequatoriensis Hack. but differs in having lemmas pubescent on the keel and marginal veins, lemma apices weakly acute, flag leaf sheath margins fused 20%–38% their length, and anthers generally larger, > 1.2 mm long. Poa subspicata var. glabrata differs from P. subspicata s. str. in having glabrous lemmas. We provide two new records for Colombia of P. huancavelicae Tovar, and P. mucuchachensis Luces. Two species, P. orthophylla Pilg. and P. reclinata (Swallen) Soreng & P. M. Peterson, are considered endemic to Colombia. Poa soderstromii Negritto & Anton is placed as a subspecies of P. orthophylla, and P. leioclada Hack. is synonymized under P. mulalensis Kunth. The names P. annua L. var. exilis Tomm. ex Freyn, P. humilis Ehrh. ex Hoffm., P. infirma Kunth, P. leioclada, P. orthophylla, P. pauciflora Roem. & Schult., P. pratensis L. subsp. irrigata (Lindm.) H. Lindb., P. puberula Steud., P. pubiflora Benth., P. subcaerulea Sm., P. subspicata, and P. trachyphylla Pilg. are lectotypified, P. mulalensis is neotypified, and P. trachyphylla is epitypified. Four species are exotic and introduced from Europe: P. annua, P. infirma, P. pratensis, and P. trivialis L. We provide a key, descriptions, illustrations, distribution and habitat information, vouchers, and notes for each species.

A new species of Tagetes, T. imbricata, is described and photographed. This species that grows in northwestern Argentina and Bolivia is characterized by annual habit, lax terminal corymbiform inflorescences, partially purplish 5-lobed involucres, and imbricated ray flowers with yellowish-white corollas. A taxonomic description complemented with photographs and a map of geographical distribution is provided. In addition, a detailed comparison of the new species and its closely morphologically similar species is also presented, as well as a key to differentiate annual species of Tagetes that grow in northwestern Argentina and Bolivia.

Zingiber hainanense (Zingiberaceae), a new species from Hainan, China, is described and illustrated. It is compared to two most similar members from Z. sect. Cryptanthium, Z. guangxiense from Guangxi, China and Z. kawagoii, an endemic species from Taiwan, China. Zingiber hainanense differs from Z. guangxiense mainly by labellum and staminodes being purple red (vs. yellowish white throughout in Z. guangxiense), and differs from Z. kawagoii by labellum and lateral staminodes being linear or narrowly ovate (vs. obovate-oblong in Z. kawagoii). The pollen morphology and chromosome number count as well as a color plate of the new species are also presented in this study.

Cyrtodactylus phnomchiensissp. nov. is described from Phnom Chi, an isolated mountain in Prey Lang Wildlife Sanctuary, Kampong Thom Province, Cambodia. The new species is recognized by having a unique combination of morphological characters, including snout-vent length 76.1–80.7 mm; paravertebral tubercles 31–36; ventral scales 45–54; enlarged femoral scales 0–8, without pores; enlarged precloacal scales 7–10, bearing pores 4–5 in males, pits 1–7 in females; the posterior border of nuchal loop unbroken and pointed, bordered anteriorly and posteriorly by a broad yellow or yellowish white band; and yellow spots on top of head. The new species also represents a divergent mitochondrial DNA lineage within the C. irregularis complex that is closely related to C. ziegleri, but the phylogenetic relationships among the new species and two divergent mitochondrial subclades within C. ziegleri are not resolved based on available sequence data. Cyrtodactylus phnomchiensissp. nov. is the only member of the C. irregularis complex known to occur west of the Mekong River. The new species may be endemic to Phnom Chi, and likely faces imminent conservation threats.

A new species of the soft-shelled turtle genus Pelodiscus is described based on seven specimens from Huangshan, southern Anhui Province, China. The new species, Pelodiscus huangshanensis sp. nov., is distinguished from other species in the genus Pelodiscus by the following characteristics: (1) Small size (maximum carapace length of 101.16 mm and maximum body length of 190 mm); (2) keel high; (3) tiny yellowish-white spots on the throat; (4) no black pinstripes around the eyes; (5) white longitudinal bands on both sides of the neck in juveniles, absent in adults; (6) plastron yellowish-white, and only a dark patch on each side of the armpit; (7) many tubercles on the dorsal surface, but indistinct in the center; and (8) entoplastron “⌒” shaped. The phylogenetic relationships of the species in Pelodiscus were reconstructed using the sequences of cytochrome b (cyt b) and NADH dehydrogenase subunit 4 (ND4) genes. The new species formed a monophyletic clade with strong support. The uncorrected pairwise distances between the new species and other representatives of Pelodiscus ranged from 5.4% to 9.2% for cyt b and 4.1% to 7.6% for ND4. The new species brings the number of species of the genus Pelodiscus to six; five species are distributed in China, with three species endemic to China.

A new species, Calvatia natarajanii, is presented as well as brief notes on the distribution of Calvatia sensu stricto and Langermannia in India. Calvatia natarajanii is distinguished by basidiomes having yellowish white to orange-white exoperidium, brownish orange to grayish red, persistent endoperidium, grayish orange to brownish orange cottony gleba, persistent cellular subgleba and globose to subglobose, echinulate basidiospores. It is described, illustrated and compared with the closely related taxa C. cyathiformis, C. fragilis, C. rugosa, C. aff. rugosa, C. pyriformis, C. vinosa and C. rosacea. Maximum Parsimony analysis based on ITS sequences confirmed that C. natarajanii is closely related to C. fragilis and distinct from other morphologically similar species. In addition, a key to the species of Calvatia and Langermannia recorded in India is presented. Four species recognized under Calvatia are excluded from the key since their transfer to Lycoperdon.

Impatiens galactica, a new species from lowland rainforest in Marojejy National Park, NE Madagascar, is described and illustrated. It belongs to Impatiens section Trimorphopetalum and is related to I. messmerae, also known from Mt. Marojejy. Impatiens galactica differs from the latter species in the shape of the lateral sepals, and in the dorsal petal and the lateral united petals being entirely glabrous and lacking small white scales. Furthermore, I. galactica has a distinct flower morphology with strongly reduced upper lobes of the lateral united petals. The lateral petals are thus resembling the lower case letter “b” or “d”, respectively. Additionally, it has unusually coloured yellowish white, semi-transparent flowers with an orange-yellow, shiny line along the midrib of the lower sepal, all of which are lacking in I. messmerae.
