Study on the section Trifoliolata DC. (Jasminum L. - Oleaceae Juss.) in Vietnam

Abstract

Jasminum L. compcises about 200 species in the world including 5 sections: Jasminum Green, Alternifolia DC., Trifoliolata DC., Primulina Green and Unifoliolata DC. they distributed in tropical and subtropical in South East Asia, Europa, Australia and Africa. Section Trifoliolata DC. was published by De Candolle (1844) with the typus Jasminum didymum G. Forst. and characterized by leaves 3-foliolate, terminal leaflet slightly larger than or equal to lateral leaflets or sometimes, lateral leaflets reduced. There are about 10 species and 5 subspecies in this Section in the world. In Vietnam, there are 1 species and 2 subspecies in section Trifoliolata DC. recorded. In this paper to we introduced Jasminum sinense Hemsl. in sections Trifoliolata DC. as a new record for flora of Vietnam. This species is found in Ha Giang (Pho Bang) and has characteristic of Trifoliolata DC. section such leaves 3-foliolate. Jasminum sinense was closed to Jasminum brevilobum by lateral leaflets reduced, leaves and calyx pilose (different with Jasminum lanceolaria subsp. lanceolaria and Jasminum lanceolaria subsp. scortechinii by terminal leaflet slightly larger than or equal to lateral leaflets, leaves and calyx glabrous). But Jasminum sinense characterized by calyx lobes linear, 1-5 mm long. In this article, we introduce nomenclature, key to species, morphology and illustration, distribution and research specimen of three species of Trifoliolata DC. section (Jasminum L.) from Vietnam.

Additions of woody climbers (Lianas) to the flora of Manipur, India

“…During field explorations, the first author collected many woody climbers (lianas) from the study area of which five were found uncommon ones. After critical morpho-taxonomic examination of all the specimens, scrutiny of relevant literature (Hooker 1875-83;Kanjilal et al 1934-39;Fang & Staples 1995;Chang et al 1996;Chen & Turland 2007;Quang et al 2013;eFlora 2017) and matching of specimens housed in herbaria of Botanical Survey of India (BSI), Eastern Regional Centre, Shillong (ASSAM) and Central National Herbarium (CNH), Howrah (CAL), the species were identified as Ampelopsis rubifolia (Wall.) Planch.…”

Nomenclatural notes and typification of nine names related to Jasminum (Oleaceae)

“…Green (1993) in one of his publications, cited these gatherings as syntypes. A survey of literature and multiple herbaria revealed that a lectotype for J. sinense has not been designated in earlier studies (Green 1993, and Bui et al 2013. While looking for the original materials, we found eight specimens of these collections deposited in IBSC, K, P and US (IBSC0002797, K000901323, K000901324, K000901325, K000901326, P00640606, P00640607 and US00112856).…”
