GENTIANACEAE 
GENTIAN A Linnaeus 
GENTIAN A CLEM ENTIS sp. nov. 
Species G. atkinsonii Burkill valde affinis, differt foliis paullo 
minoribus, floribus paullo brevioribus, corollae lobis haud reticu- 
latis, acutis. 
A caespitose, perennial, glabrous plant 10 cm high or less, 
from stout, elongated, perpendicular roots, the basal leaves rosu- 
late, the flowering branches up to 6 cm in length, spreading or 
ascending, several from each plant, leafless or with but one pair 
of leaves in addition to those subtending the flowers. Basal 
leaves 3 to 5 cm long, 4 to 6 mm wide, coriaceous, shining, sessile, 
lanceolate, acuminate, the midrib prominent, those on the flower- 
ing branches similar to the cauline ones but smaller. Flowers 
pale-purplish, sessile or subsessile, 2 to 4 at the apex of each 
branch, subtended by a whorl of 2 to 4 bract-like leaves. Calyx- 
tube 6 to 8 mm long, narrowed below, the teeth lanceolate, 
acuminate, 3 to 4 mm long. Corolla about 2.3 cm long, the 
lobes oblong-ovate, acute, 5 mm long, the tube narrowed below, 
plicate, the alternating small lobes triangular-acute, about 1 mm 
long. Stamens about as long as the corolla-tube ; style recurved, 
3 mm long. 
British North Borneo, Mount Kinabalu, Paka Cave to Low’s Peak 
and Paka Cave to Lobang, Mrs. Clemens 10703 (type), 10650, November 
13 and 15, 1915, in wet ground, associated with Potentilla, altitude 2,400 
to 4,000 meters. 
This is the third representative of the genus to be found in Borneo, the 
other two being known only from Mount Kinabalu, and both of them 
represented in Mrs. Clemens’s collection. It is a distinct Asiatic type 
and is very closely allied to Gentiana atkinsonii Burkill, a species known 
only from Loh Fau Mountain, Kwangtung Province, China, of which I have 
a topotype ( Merrill 10326). It so strongly resembles Burkill’s species 
that had the specimens described above been collected on Loh Fau Mountain 
it is very probable that botanists generally would have referred them to 
Gentiana atkinsonii Burkill as a somewhat reduced form. The Kinabalu 
specimens differ from Burkill’s specimens in the small size of the plants, 
the shorter flowering branches, smaller leaves, and somewhat smaller 
flowers.
