Anamalai Mountains. Sholai Aar, near Monica estate, 
at 3,500 feet, Willis ! C. A. Barber, S. Ind. Flora, 
No. 3,813 ! 
Very closely allied to the preceding, but recognizably 
distinct, especially when living. 
H. olivaceum griseum (H. griseum, Tul.), 
Thallus rather deeply lobed. Primary axis larger than in 
zeylanicum, often floriferous. Spathe scabrous. Bracts 
coarser than in zeylanicum, often 8. Thallus often 
decaying between the secondary axes before exposure. 
Colour grayer when dry. 
Nilgiri Mountains. Paikara river, 5,000-6,000 feet.

in Warming, 1. c. IV. (D. apicata) Î Willis ! 
There are some primary axes, probably of this form or 
one closely similar, preserved in herbaria, purporting 
to have been collected near Bombay by Dalzell. It 
is by no means improbable that this species is to be 
found there. 
This species is very easily distinguishable by its crus- 
taceous thallus and erect stalked clearly-ribbed fruit. H. 
sessile and lichenoides both at times show tendencies to 
crustaceous thalli, but one has the fruit-ribs confluent below 
the apex of the fruit, the other is smooth-fruited. The 
primary axes, when seen, were formerly described as in- 
dependent species, Podostemon Gardneri and Dicræa apicata. 
H. JOHNSONII (Wight), Willis ; Mniopsis Johnsonii, 
Wiglit^ leones, 1. 1,919. Podostemon Johnsonii, Wedd.^ 1. c.. 
Hooker in FI. Br. Ind. 
Thallus crustaceous (?). Fruit shallowly 8-ribbed. 
Stamens much exceeding gynæceum. 
Primary axis not seen, Thallus, judging from fragments and from 
Wight’s description, as in H. olivaceum, crustaceous, with oo secondary 
shoots scattered over the surface. Spathe opening by longitudinal 
slit on the upper side. Flower erect on short pedicel. Stamens 2^ 
times as long as ovary, on long common filament ; staminodes shorter 
than ovary. Ovary more or less globose, with long subulate stigmas.
