“S.E. Tibet :—Ka-gwr-pw Temple. Abies forest. Alt. 
15,000 ft. July 1913.’ F. Kingdon Ward. No. 88r. 
A dwart plant belonging to the series Fragiles of Prain and a 
near ally of P. Legendrei, Bonati. It differs from that species 
by its small size, its stems sub-lignose at the base, its corolla 
yellow and hood glabrous on the back and scarcely ciliate on the 
edge, the lower lip very short, and finally by its staminal fila- 
ments being all glabrous. It differs from P. Kingii, Prain of 
which the corolla is white, by its calyx not split in front, by its 
filaments being glabrous and inserted at the base, by the form of 
its leaves, ete. 
The series of the Fragiles of the section A nodontae-verticillatae 
now contains four species which can be easily distinguished by 
the following table. 
A. Calyx split in front; corolla white, hood without beak and 
with glabrous edge; lower lip glabrous, two filaments 
airy. ‘ : : ‘ es Kingit, Prain. 
B. Calyx split in front ; lower lip ciliate. 
*Hood without beak, calyx with very short lobes. 
+ Plant of large size; corolla rose; hood hairy on the back 
and on the edge; lower lip nearly as long as the hood; 
two filaments hairy. . 2. P. Legendrei, Bonati. 
+ +Plant dwarf; corolla yellow; hood glabrous on the back 
and on margin, scarcely ciliate at the base; lower lip 
much shorter than the hood ; filaments all glabrous. 
: : : : : 3. P. Wardii, Bonati. 
**Hood terminating in a beak short and truncated, calyx 
with lobes elongated ; corolla green. 4. P. fragilis, Prain. 
If we seek to determine what is the geographical distribution 
of the series of the Fragiles we find that :—P. fragilis, Prain and 
P. Kingit, Prain both inhabit the Eastern Himalaya, the first 
Assam, the second Sikkim and Chumbi; P. Legendrei, Bonati 
has been found up to the present only from Eastern Szechwan; 
finally P. Wardii, Bonati is known so far only from S.E. Tibet.
