366 Scott Elliot. — On the Fertilisation of South 
a contrivance to produce self-fertilisation in case the first 
stigma adapted to cross-fertilisation should receive no pollen. 
Visitors: — Apis mellifica ? also a Bombylid, Pangonia angu- 
lata ? — Muizenberg, Cape Town. 
Taehiadenus. 
In this genus the stigma is well above the anthers. 
Honey is secreted by a minute ring round the ovary. Visitors : 
— Lepidoptera abundant. — Imerina and Fort Dauphin. 
Ipomoea palmata, Forsk. 
The stamens are united to the corolla for about 3 
lines and by bending forward towards the style leave a sort 
of chamber below in which honey is secreted. The nectary 
is in the form of a ring round the ovary. The staminal fila- 
ments are very hairy and the pollen appears to drop on to 
these hairs. Insects creeping down the corolla will receive 
pollen on their back from the anthers in young flowers and 
touch the style in older ones. Visitors : — Apis mellifica and 
Coleoptera. — Fort Dauphin. 
Ipomoea Pescaprae, Roth . 
The filaments are not united to the corolla. Cf. Bur- 
ger stein (Macleod, No. 64 a). 
Bobostemon frutieosum, Buek. (Fig. 100.) 
The flower is distinctly protandrous. The stamens are of 
different lengths varying from 5 lines (superior) to 9 lines 
(inferior). A honey chamber is formed by the hairy pro- 
jecting bases of the filaments (h in figure). Subsequently 
the style elongates growing beyond the anthers. Visitors : — 
Hymenoptera : Xylocopa cajfira^ Apis mellifica , Ceratina sub- 
quadrata , Tetratonia longicornis. Coleoptera : Anisonyx ursus , 
A. longipes , Dichilus dentipes , D. simplicipes , Peritrichia capicola. 
For Xi. montanum, see Ann. of Bot. 1 . c. p. 271. 
Lyeium capense, Mill, non Thunb. (Fig. 101.) 
This is extremely similar to Lyeium barbarum described 
by Muller. The nectary is a small ring round the ovary. 
Visitors: — Apis mellifica , ab. also various butterflies. — Fort 
Dauphin.
