The genus Alchemilla L. is one of the largest in angiosperm. This paper deals with variability of leaf blade characters of some microspecies from Alchemilla L. genus. The studies were conducted in 3 natural regions on the territory of Mari El Republic and in culture. A consensus configuration of leaf blade for A. acutiloba Opiz, A. gracilis Opiz, A. monticola Opiz, A. sarmatica Juz., A. schistophylla Juz., A. substrigosa Juz. was obtained by a geometric morphometrics method. The variability of the leaf blade shape for A. acutiloba, A. gracilis, A. sarmatica in natural cenopopulation was described. The study has shown that the size and shape of leaf blade for A. gracilis in ecologically contrasting conditions differ. The size of leaf blade for A. substrigosa differs in conditions with some differences in the ecological characteristics of soils, the shape does not differ. According to a discriminant analysis based on a complex of morphometric characters of leaf blades for microspecies A. litwinowii, A. monticola, A. substrigosa in meadow plant community are classified with an accuracy of about 80%. A similar classification result of leaf blades for A. acutiloba, A. gracilis, A. hirsuticaulis in culture was revealed. Leaf blades for different microspecies form distinct, but overlapping clouds in the plane of discriminant functions.

A new species of Gesneriaceae, Primulina porphyrea, is described and illustrated from southern Hunan, China. The new species resembles P. polycephala and P. yangshuoensis in leaf blade shape and indumentum of the plants, but it can be easily distinguished by having long petiole and purple leaf abaxial surface, purple corolla lobes and yellow corolla tube with several reddish-purple stripes, dark yellow filaments, and 3 staminodes. It flowers from May to August.

Two new species of the genus Anthurium are described from the Serra do Brigadeiro State Park, in the Atlantic Forest region, southeastern Brazil. Anthurium atrovinosum was found from 1450 to 1720 m and A. brigadeiroense from 1260 to 1650 m. Although they are sympatric species, A. atrovinosum reaches higher elevations, while A. brigadeiroense can be found up to 1650 m. Both belong to Anthurium sect. Urospadix subsect. Insculptinervia, but are easily differentiated by the leaf blade shape, fruit color. Descriptions, illustrations, photographs, comments on geographical distribution, ecology, phenology and comparisons with other similar species are presented.

ABSTRACT Caraipa andina from La Fundación, in the western Andes of Venezuela (Táchira State) is described, illustrated, and its morphological relationship with an allied species is discussed. This new species is morphologically related to C. heterocarpa Ducke, but it differs by the leaf blade shape, size, and dense abaxial papillae; fewerflowered inflorescence; and shorter pedicel, flower buds, petals, and filaments. Phytogeographical information about the La Fundación area is presented. This species represents the first report of this genus in the Venezuelan Andes.

Investigations on seedlings of Sida acuta Burm. f. subsp. acuta, S. cordifolia L., S. javensis Cav., S. ovata Forssk., S. rhombifolia L., and S. spinosa L. have been carried out to assess the systematic relevance of seedling morphology within the genus Sida L. The seedlings are found distinct with respect to collet shape, paracotyledon blade apex, epicotyl surface, stipule, leaf blade shape and venation, type of hairs, and presence or absence of spines. The results on morphological attributes of seedlings in the genus Sida L. are of high systematic value of the family Malvaceae.

A New Species

Impatiens bijieensis X.X. Bai & L.Y. Ren, a new species from Northwest Guizhou, China, is here described and illustrated. This new species is distributed discontiguously in Jiulongshan of Dafang County and Dajiucaiping of Hezhang County, both of which belong to Wumeng mountains area, a karst plateau landform. It is morphologically similar to I. lasiophyton J.D. Hooker and I. leptocaulon J.D. Hooker in height, leaf blade shape and flower form, especially resembles I. lasiophyton in pilose plant. However, it differs in its deep purplish-red to rose-red flower, 2-lobed lower sepal apex and cylindrical capsule. A detailed description, color photographs, and a provisional IUCN red list assessment are provided, and its geographical distribution, ecology, and morphological relationship with relevant similar species are discussed.
