372 Scott Elliot . — On the Fertilisation of South 
of which point upwards, and by using a bristle, I came to the 
conclusion that the pollen (which seems to come out bodily 
from the four anthers) cannot be forced down the tube but is 
only removed on withdrawal. It is difficult to see how pollen 
can be introduced to the stigma as these hairs would tend to 
prevent it, but probably they eventually wither. Visitors : — 
Coleoptera : gathering pollen. Diptera ; a Bombylid ? Probably 
the main fertilisers are night-flying moths. 
Disehisma ciliatmn, Chois. (Fig. 114.) 
The flowers are marked with red and fairly conspicuous 
from their aggregation in a pretty long raceme. The corolla 
has a delicate tube about 4 lines long which is split half-way 
to the base. Probably this apparent splitting is due to the 
non-development of one petal which is represented as a small 
tongue at the end of the slit. There is a difference in the 
shape of the anthers ; the two upper anthers being horizontal 
and the two lower vertical (cf. Z aluzianskya , Phyllopodium , 
Maniilea). The style projects a long distance out of the 
corolla, and is curved with the concavity of the curve ap- 
pressed to the rudimentary petal. The flowers are visited by 
Apis mellifica which, as I saw clearly, plunged its head 
between the anthers and touched the stigma with its abdomen. 
The method of fertilisation is therefore identical with that of 
Chaenostoma (p. 368). 
Ocimum hians, Bth . 
The stamens and style are both widely exserted in this 
flower, but the latter lies well in front of and above the an- 
thers. The essential organs are not in contact with the lower 
lip because the staminal filaments curve upwards in a slanting 
direction. There is a hairy enlargement of the filaments in 
the throat of the corolla which probably completely excludes 
small insects from the honey. (Cf. Sprengel, who pointed this 
out in 1793, Muller, No. 702.) 
Synelostemon densiflorus, E. Mey . 
The mechanism and shape of this flower is very similar 
to that of Plectranthus Eckloni. The outer stamens roll
