Notes.
Chantaranothai and Parnell (1993)
proposed
subsp.
minor
for Thai material with a slightly shorter hypanthial cup (
3–4 mm
long vs
5 mm
long for the typical variety), stamens and style. After examination of
Gardner & Chamchumroon ST 2467
K [001007729], a second new specimen collected from
Trang
,
Thailand
, I found that these characteristics are variable. Therefore,
subsp.
minor
is here placed into synonymy of
S. prainianum
. This species is uncommon in
Thailand
but widespread in Peninsular
Malaysia
and Borneo.
