Sikkim, at elevations between 4,000 and 6,000 feet; in flower during October and 
November, common; Pantling, No. 12. Westward to Ranken and eastward to Bhutan.

The flowers of this have a ground colour of ochraceous do with numerous 
vertical lines of warm brown, the lip having broad transverse blotches of the same tint, 
externally the sepals are flushed with green. In habit and leaves the species much 
resembles C. grandiflorum; but the flowers are smaller, differently coloured and appear 
much later in the year.. In the figure of this in Bot. Mag., No. 4844, the flowers are 
coloured by far too green.

10. CYMBIDIUM GRANDIFLORUM, Griff. Notul. III, 342, 
Pseudo-stem very short. Leaves linear-oblong, acute, entire, narrowed towards the

The sepals and petals are apple green, the margins being of a paler tint; the lip 
and column are ochraceous yellow speckled with purple. This species often attains а 
greater size than is given in the preceding description, the scape and raceme together 
sometimes measuring 3 to 5 feet in length; and the latter having as many as eighteen 
flowers. After fertilization of a flower has been effected the column and lip become 
red in colour. The flowers are fragrant. E
