ANGIOSPERM AE. 
MONOCOTYLEDONEAE. 
PANDANALES. 
Typhaceae. 
The genus Typha L. has not been recorded in the southern coast belt 
from localities west of Van Stadens. It is found, however, in the Karroo 
and in the eastern and north-eastern parts. 
HELOBIAE, 
Hydrocharitaceae. 
This order is represented in South Africa only by one species of 
Lagarosiphon Harv. It has its western limits at the G-aintoos River, and 
extends to Natal and the Transvaal. 
Potamog^etonaceae. 
It is curious that out of five species recorded of Fotamogeton L. in the 
Uit. and P. E. div. four have not been collected recently. This may be due 
to insufficient attention having been paid to them, possibly also to drainage 
of places where previously conditions for their growth were more favourable. 
Zostem L. occurs in the tidal portion of the Zwartkops River (also recorded 
from the Kleinriver Vley and from Natal). Ruppia, L. is only recorded 
from the Cape div. and ZanmchelUa, L. from western and northern parts. 
Naiadaceae. 
Naiag L. is recorded from the Transvaal only. 
Aponogetaceae. 
Aponogeton Thunb. extends from north-eastern and eastern parts, mainly 
through the coast districts to the Cape div., but -also into the central parts 
to the Somerset East and Richmond divs. 
Scheuchzeriaceae. 
Triglochin L. is found in the coast belt from the Cape Peninsula to 
Natal, going inland to the Paarl and Griqualand East. 
GLUMIFLORAE. 
Gramineae. 
Without taking into account obviously introduced genera almost all 
genera of more or less general distribution are recorded from the Uit. and 
P. E. divs. Exceptions are Anthoxanthum L. (the species of which have
