5 . rhombifolia . The venation of the leaves, their texture and 
serrature, the shape, size and colour of the flowers are exactly 
the same, so that I am disposed to consider them as mere 
individual variations, the more, as the type specimens are 
derived mostly from the same place, Hinidoon. Thus also 
S. glaberrima evidently belongs to the same species. Next 
S'. pU 7 nila follows as a new species in Thwaites’ enumer- 
ation. It is merely a dwarf form of the typical zeylanica , 
and was found in the more elevated parts of Ceylon. Clarke 
made it a variety of 5 . zeylanica , but I should not go even so 
far, but consider it as a form which might be derived any- 
where from the typical S'. zeylanica , when this is exposed to 
unfavourable conditions of growth. Cogniaux re-established 
it as a species apparently on account of the supposed smooth- 
ness of the seeds. But smooth and glandular-dotted seeds 
may be found in the same capsule. The last member of this 
difficult set is 5 . cor difolia, Cogn. It was named originally 
S'. zeylanica , W. et A.., forma cor difolia by Thwaites in sched ., 
and indeed it is nothing but a rather flaccid form from the 
Singhe Rajah Forest, probably from a very shady place. The 
leaves are more rounded at the base, and sometimes even 
cordate, but the same may be observed occasionally in typical 
S. zeylanica. The anthers are of the short acute type. 
For these reasons I bring the whole set of these hardly 
distinguishable forms into one species, .S', zeylanica , and main- 
tain only the most marked ones as varieties, viz. : 
(a) v. vidgaris , Stapf : anthers short, acute or obtuse, not 
over 3 mm. long, leaves with distinct more or less spreading 
serrature (Syn. S.pumila , Thw., S', cordifolia , Cogn., S', zey- 
lanica, W. et A. sensn strictiore). 
(/ 3 ) v. affinis , Stapf : anthers more attenuate or rostrate, 
3*5“7*5 mm * long, leaves with usually distinct, very spreading 
serrature (Syn. S. affinis, Arn., S. rhombifolia, Thw.). 
All the localities hitherto known for S', zeylanica in this 
broad sense are limited to the centre and the South-west of 
Ceylon, in elevations from 600-1800 m. It is the more re- 
markable that this plant was recently found by G. D. Havi-
