and S'. Clarkei , where they attain 6-7 mm., with those of the 
variety ajjinis. 
II. Group of S. Gardneri. Central and South-west Ceylon. 
The species of this group are small, more or less woody under- 
shrubs with sessile or subsessile leaves with 3-7 basal nerves 
and short comparatively broad capsules. The tendency to 
forms with short and long anthers is also here very obvious, 
another parallel to the two series in the zeylanica-^ roup. 
1. S'. Gardneri , Thw. Central Ceylon, 1500 m. 
It is distinguished by very short petioles, broadly ovate 
leaves, a tomentum exactly like that in S'. wightiana , and 
short anthers, and particularly by its broad , ellipsoid capsules. 
There is a variety firma , Triana, with sessile leaves which 
approaches closely the following species. 
2. S'. robusta , Arn. Central Province, 1800-2100 m. 
3. S'. Harveyi , Thw. Central Province, 1800 m. 
S'. robusta has capsules more like those of S. wightiana , 
and the anthers are long and rostrate (5-6 mm.). The hairi- 
ness of the stem, the foliage, and the inflorescence, is subject to 
great variation, and it is sometimes almost suppressed (v. gla- 
bricaidis , Thw.). 6'. Harveyi is very similar, but it has short 
anthers (3*5-4 mm.), and it is still more glabrous. Further 
investigation will probably prove it to be a slight variety of 
►S', robusta , to which it stands in an analogous relation as 
►S', zeylanica v. vulgaris to v. affinis. 
4. S. lanceolata , Thw. South-west Ceylon, 300 m. 
It is the most aberrant form of the group, quite glabrous 
with sessile lanceolate indistinctly crenate leaves and almost 
obconical capsules more like those of S'. Brunonis. 
The group is separated from that of S', zeylanica by a very 
distinct gap ; its members, however, are (with the exception of S'. 
lanceolata ) in the closest relationship to each other. They show 
tendencies in their variation quite parallel to those which become 
evident in the first group, and they inhabit also the same area. 
III. Group of S. versicolor. South-west Ceylon; Western 
Ghats northwards to the Nilgherries. 
Whilst in all species mentioned hitherto the lateral nerves
