Inocybe pakistanensis is described and illustrated as a new species based on morphological characters and molecular phylogenetic analysis of nuclear ribosomal DNA including the internal transcribed spacer (ITS) regions along with larger subunit (LSU). The distinctive basidiomata have a highly rimose and fibrillose golden brown pileus with a reddish brown, prominent umbo; ellipsoid to amygdaliform, slightly phasoeliform smooth basidiospores; and clamped septa in all the tissues. Molecular phylogenetic analysis supports the placement of I. pakistanensis in section Rimosae s. str.

Twenty-six new species of Saussurea (Asteraceae, Cardueae) from the Qinghai-Tibetan Plateau and adjacent regions are described and illustrated. Our molecular phylogenetic analysis based on the nuclear ribosomal DNA internal transcribed spacer (ITS) and two chloroplast DNA fragments (trnL-F and psbA-trnH) has shown that most of the new species are well recognized in the molecular tree, with their taxonomic affinities also largely revealed.

Infundibulicybe macrospora, a new species, is described and illustrated from the Himalayan moist temperate forests of Pakistan. The new species can be differentiated from close allies by its reddish orange to light orange pileus, whitish lamellae and stipe, and larger and broader basidiospores. The new species is also supported by molecular phylogenetic analysis inferred from internal transcribed spacer (ITS) region.

Euphorbia mbuinzauensis, a succulent new species of the Synadenium group in Euphorbiaceae from Makueni County, Kenya, is described and illustrated. Morphologically, it is most similar to E. pseudomollis, but differs mainly by its shrubby habit (up to 4 m), abaxial leaves surfaces with densely stellate hairs, 2–4-forked cymes, smaller bracts (ca. 2.5 × 3.0 mm), smaller cyathia (6 mm wide), crimson glands without narrow smooth margin, smaller fruits (ca. 8 × 7 mm) and ovoid seeds (ca. 1.8 × 2.2 mm). Furthermore, we performed a molecular phylogenetic analysis of the Synadenium group in Euphorbia sect. Monadenium, based on complete nuclear ribosomal DNA (nrDNA) datasets. This phylogenetic inference also supports it to be a distinct species. The new species is assessed as Endangered using the IUCN criteria.
