in South Africa. 
Lycium tubulosum, Nees. 
This plant is a tall shrub or small tree, with drooping white 
flowers. The corolla is ten lines long and considerably curved. 
The stigma is always in front of the stamens, so that cross- 
fertilisation is ensured. Honey is secreted by the base of the 
ovary. 
I found it was abundantly visited by Nectarinia chalybea on 
the banks of the Little Fish River, near Somerset East. It 
is also much visited b y Apis mellifica and other Hymenoptera, 
who crawl bodily into the flower. Various Coleoptera also 
visit the flowers. 
Lobostemon montanum, Buek. 
This plant is a shrub some four or five feet high. The 
leaves are crowded at the ends of the branches, and these 
latter being very close together, the bush forms a sort of 
domed cushion closely covered by pale purple flowers. 
The flowers are distinctly irregular : the posterior lobes of 
the corolla are shorter than the anterior and the stamens of 
unequal length h 
Honey is secreted very abundantly by a fleshy ring round 
the ovary, sometimes filling the corolla-tube to a depth of 
two or three lines. Insects are kept out largely by a ring 
of hairs springing from the base of the filaments (and corolla) 
which surrounds the style. The whole plant is excessively 
hairy, and the corolla externally viscid. 
Though this flower is not specially adapted to birds, I have 
often seen it visited by Nectarinia chalybea sucking honey, and 
also by other birds (? Promerops caper ) near Muizenberg. In- 
sect visitors moreover are very rare. 
The nearly allied Lobostemon fruticosum , Buek., is always 
covered by insects. The following I have gathered myself. 
Coleoptera : Anisonyx ursus always very ab., Anisonyx longipes 
ab., Dichilus dentipes , D. simplicipes , Peritrichia capicola , and 
others which I cannot name. Hymenoptera : Ceratina subqua- 
1 The shorter stamens twelve lines long, and the others thirteen or fourteen 
lines.
