368 Scott Elliot. — On the Fertilisation of South 
Zaluzianskya coriacea, Walp. (Fig. 103.) 
In this genus the stigma projects out of the corolla-throat 
and must first come in contact with an insect standing on the 
limb. The two anterior stamens are exserted and their 
anthers are transverse or horizontal during dehiscence, while the 
posterior anthers are wholly included and their anthers dehisce 
parallel to the corolla-tube, lying close to its lower surface. 
The nectary is chiefly developed on the upper part of the 
ovary at the base of the flower. The length (14 lines) of the 
corolla-tube would lead one to suppose Lepidoptera to 
be the chief fertilisers of this flower. The limb appears to 
be closed over the corolla-entrance in dark or cloudy weather. 
Phyllopodium diffusum, Bth . 
The stigma stands well in front of the anthers and of the 
entrance to the corolla-tube. The longer stamens are ex- 
serted and dehisce outwards with anthers inclined at 45 0 to 
the horizon : the shorter stamens are almost wholly included 
and dehisce upwards. Visited by a long-tongued Dipteron 
remarkable for the extremely hairy yellowish brown abdomen. 
— Near Cape Town. 
Chaenostoma polyanthum, Bth. 
The style and anthers are both exserted in this species. 
One insect (? Odynerus , sp.), which I was able to watch, was 
standing tipon the style and inserting its head between the 
reniform anthers. Also visited by Diptera. — Somerset East. 
Manulea Cheiranthus, L. (Figs. 104, 105.) 
In this genus there is a very short style which only 
reaches about half-way up the corolla-tube. The anthers are 
both included in a slight dilatation just below the throat of 
the corolla. On looking at the corolla from in front, it will 
be seen (see Fig. 105) that the transverse section of the tube 
is not circular, but that, owing to a folding inwards of the lines 
of union of the petals, two canals are formed opposite the two 
upper petals down which an insect’s proboscis must pass 
c, c (see Figs.). The ridges between these canals and the 
canals themselves are continued inwards for about one line
