4. 5 . scapigera, Dalz. Baba Badun Hills to the Bombay 
Ghats. In .S'. Wallichii the stem is reduced to a very short 
rhizome which is rather thick and covered with fibrils. The 
leaves, few in number and often very unequal in size, rise from 
the rhizome as true ‘ radical 5 leaves, and with them the scapelike 
peduncle. They are long petioled, always more or less cor- 
date, and exhibit sometimes even a tendency towards becoming 
peltate. The nervation is similar to that in 5 . Rheedii ; three 
nerves spring from the base on each side of the middle nerve, 
whilst another pair and 3-5 alternate nerves spring higher up. 
It is the type of the nervation which was meant by Bentham 
(Bennet et Brown, PI. rar. Jav. p. 215) under the term ‘hetero- 
neura.’ But sometimes the first two are alternate or, on 
the other hand, some of the upper ones opposite. 5 . sca- 
pigera differs by smaller leaves, generally longer anthers and 
the narrower white margin of the capsules. The anthers vary 
from 3-5 to 6*5 mm. in length, against 3 mm. in .S'. Wallichii. 
There is, however, but scant material of .S'. Wallichii before 
me, and future investigation may possibly prove the latter 
to be only a large-leaved variety of .S', scapigera. 
5. .S', rotundifolia , Bedd. Anamally Hills. 
This species is also closely allied to .S', scapigera. It has 
a very small and short rhizome from which the leaves and the 
peduncle spring, the former being orbicular-ovate and purplish 
beneath and very similar to those of 5 . scapigera . Also the 
inflorescence is the same, but more reduced, often to a single 
flower. The ^anthers are smaller (2 *5-3-5 mm.) and not 
rostrate.
