Jasminum macrocarpum Merr. (Oleaceae), A Newly Recorded Species from Vietnam

越南木樨科植物新记录



全 文 :Oleaceae are a tropical and subtropical family
comprising 28 genera and approximately 450 species[1–2].
The genus Jasminum was established by Linnaues[3]
and consists of 200 species distributed in tropical
and subtropical regions in South East Asia, Europe,
Australia and Africa[1,4–5].
In Vietnam, the genus Jasminum was taxonomically
studied by several authors[6–8], and currently 29 species
has been reported[8]. After examining all the specimens
of Jasminum from Vietnam kept at HN, four specimens
collected in 2011 from Kon Ha Nung Forest Station,
Kbang District, Gia Lai Province, South Vietnam,
are found to be different from known Vietnamese
species by leaf blade many lateral vein (8 – 9 pairs),
inflorescence 5-many flowers, calyx pubescent, calyx
lobes reflex, corolla white to purplish, berry subglobose,
2–2.5 cm in diam. Furtheer studies reveals that it
represent a newly recorded species from Vietnam,
J. macrocarpum Merr. This species belongs to
Unifoliolata leaf group, and is closed to J. anodontum,
J. coffeinum, J. simplicifolium subsp. sootepense, J.
pierreanum and J. scandens in the calyx lobes shorter
than calyx [tube].
