DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 209 
is very short. It approaches most to Gentiana Ettingshausenii, F. v. Muell., from the 
Owen Stanley Range in New Guinea. 
GENTIANA BORNEENSIS, Hook. fil. in Hook. Ic. Pl. t. 1440 B. 
Temburungo, alt. 7500 feet (Haviland, 1160; Low). 
From the more complete material now in my hands, this species is doubtless 
specifically distinct from G. guadrifaria, Blume, though allied to it. 
SOLANACE i. 
SOLANUM BIFLORUM, Lour., Fl. Cochinch. 129, not of Don. 
On Kinitaki River, alt. 4000 feet (Low); alt. 5000 feet (Haviland, 1234). 
Distribution : Throughout Tropical Asia. 
It seems to me very probable that S. subtruncatum, Wall, S. bigeminatum, Nees, 
S. leve, Dunal, S. denticulatum, Blume, S. macrodon, Wall., S. crassipetalum, Wall., and 
probably also S. bimense, Miq., and S. nematosepalum, Miq., are only forms of one very 
variable species which was first described by Loureiro, under the name of $. biflorum. 
The supposed differential characters which are derived from the shape of the leaves, the 
indumentum, the presence or absence and the length of the calyx-teeth are in reality very 
inconstant, and they hardly allow the distinction of geographical subspecies or varieties. 
The Kinabalu plant is very similar to the form described as S. leve by Dunal, but the 
linear calyx-teeth rise from below the calyx-limb. They agree also in ali characters with 
S. Blumet, Nees, but for the presence of calyx-teeth. From typical S. denticulatum they 
differ chiefly in the glabrous leaves, and from S. biflorum, Lour., as it is usually represented 
by the Chinese specimens, in the glabrous or almost glabrous calyx and shorter, less acute 
teeth. Some of the Khasia specimens, named 5. crassipetalum, Wall., and S. macrodon, 
Wall., agree almost exactly, or they differ solely in the length of the teeth or the presence 
of a more copious tomentum.
