Indopiptadenia oudhensis (Brandis) Brenan is a threatened and an endemic legume forest tree genus of tropical moist deciduous forest of lower foothills of Himalaya. As population status of the species is declining at alarming rate, molecular characterization and germplasm conservation is urgently needed. This is the first attempt to draw its phylogeny based on molecular level and evolutionary closeness with other legumes. Among three barcode genes i.e rbcL, matK and ITS, only rbcLaF-rbcLaR gave satisfactory amplification and proved that rbcL is still working well than other barcode genes and justifies the evolutionary affinities with other legume species. Based on nucleotide homeology, the species is closely related to Prosopis cineraria and demonstrated nucleotide variation at only one site (552; A>G). Based on rbcL gene sequences and phylogeny, its evolutionary linkages found similar to the species placed in subfamilies Mimosaoideae and Caesalpiniodeae. However, researchers working on legume phylogeny clearly mentioned that Indopiptadenia is a part of clade mimosoid of Caesalpinioideae based on morphology. Hence, Indopiptadenia oudhensis may be the connecting species between subfamilies Mimosaoideae and Caesalpiniodeae.

Abstract Total DNA was extracted from 41 species (20 genera) of the subfamily Nepetoideae (family Labiatae). Using rbcL-specific primers, the rbcL gene was amplified by polymerase chain reaction (PCR) and sequenced directly. RbcL sequences were evaluated with character state (maximum parsimony; PAUP) and distance methods (neighbour-joining; MEGA). In agree­ ment with classical systematics all taxa studied cluster within the Nepetoideae and are clearly distinguished from members of the subfamily Lamioideae. A number of distinctive clades are apparent within the Nepetoideae:, and XIII -Perovskia. At least five main branches rep­ resenting the clades I, II, III to VII, VIII, and IX to XIII respectively, can be distinguished within the Nepetoideae studied. They might be considered representing the tribes (according to Cantino, 1992) Elsholtzieae (I), Lavanduleae (II), and Mentheae (III - XIII). The tribe Mentheae needs to be subdivided into at least three main groups (clades III-VII, VIII and IX -XIII). Major ana hortensis which is often classified as Origanum hortensis does not cluster with Origanum and deserves a generic status of its own.

The systematic position of Pterogonidium pulchellum (W.J. Hooker) Muell. Hal. in the Sematophyllaceae and Piloecium pseudorufescens (Hampe) Muell. Hal. in the Myuriaceae is reexamined with new evidence derived from rbcL gene sequences. A total of 18 taxa from Sematophyllaceae, Hypnaceae, Myuriaceae, and Hookeriaceae were included, 11 of which were newly sequenced for the rbcL gene. Analyses were done using maximum parsimony, maximum likelihood (TrN + Γ + I model and GTR + Γ + I model), and Bayesian inference (GTR + Γ + I model). The results show that Pterogonidium pulchellum has a closer relationship with members of Hypnaceae than with Sematophyllaceae, while Piloecium pseudorufescens forms a clade with the Sematophyllaceae in all phylogenetic analyses, with robust branch support. Two SOWH tests were carried out and the results show that it is not appropriate to classify Pterogonidium pulchellum in Sematophyllaceae and it is also not appropriate to classify Piloecium pseudorufescens in Myuriaceae.
