superior 2 lin. longa obtusa vel erosula, trinervis, sparse pilis 
longis patulis obsita; florens oblongo-lanceolata, 2 lin. longa, 
saturate glauco-violacea, apice obtusiuscula minute denticulata 
et ciliolata, trinervis, nervo medio haud vel brevissime excurrente, 
patule pilosa. Palea vix brevior acuta, sparse pilosa. Lodicule 
truncate, obtuse lobulate. Anthere 1 lin. longe. Ovariwm 
glabrum, stylis paulo brevioribus, stigmatibus aspergilliformibus. 
Sandy soil in valleys, 15,800 ft. (no. 120). 
D. serotina has been referred by Mertens and Koch, Grisebach 
and others to Molinia, and although it does not answer exactly to 
the type on which the genus Diplachne was founded by Beauvois, 
i. e. D. fascicularis, Beauv., a North-American species, I prefer 
to leave it in that genus following the authority of the authors 
of the ‘Genera Plantarum,’ of Parlatore and of Hackel, and 
consequently I also refer the new species to the same genus.

Wide valleys, 17,000 ft. (no. 78); close to water, 16,200 ft. 
(no. 88), 16,500 ft. (no. 111).

nana. 
Close to water, 16,200 ft. 
The first form differs from the typical Atropis distans, as we 
usually find it in Europe, only by its dwarfness, the smaller 
specimens being 2-3 inches high with panicles 3 inch long and 
broad. The variety convoluta is likewise represented by dwarf 
specimens about 4 inches high, but they agree otherwise perfectly 
with the form of Atropis distans which prevails in the North- 
western Himalaya and which is identical with the plant described 
by Grisebach under the name of A. convoluta. This variety 
extends from Tibet to the Altai and westward to South Russia. 
108. Festuca ovina, Linn., var. valesiaca, Koch; cf. Hackel in 
Boissier, Fl. Orient. v. p. 618. 
At 16,500 ft. (no. 110). 
A common grass in the higher parts of the Himalaya from the 
Afghanistan frontier to Sikkim, here from 12,000 ft. ascending 
to 17,000 ft. (Donkiah Pass, J. D. Hooker).
