proportion being forty, twenty-nine, and thirty. Probably a 
sufficiently large series would make these differences vanish, 
at least in part. 
Impatiens capens©, Thunb . 
The flowers are protandrous, and the inclination of the 
spur is such that an insect must touch the anthers while its 
proboscis is in the spur (see Muller, p. 160). — Perie bush. 
Adenandra obtusata, Sond. 
This agrees in most respects with A. fragrans , R. & 
Sch., thoroughly described by Urban (Macleod, No. 557). It 
is markedly protandrous, and in young flowers the style is 
bent down amongst the peculiar stalked glandules which cover 
the ovary. The stamens are at first bent inwards, but as they 
mature they successively rise so that they dehisce between 
the staminodes. Each anther bears a little glandular stalked 
knob, which is at first directed inwards, but becomes reflex 
during dehiscence (probably this secretes a substance which 
makes the insect’s proboscis sticky, as Urban suggests). The 
staminodes are longer than the stamens, and their inner 
surfaces are covered with white hairs ; they are at first bent 
in, but subsequently become erect. The style eventually rises 
and becomes upright in the centre of the flower. I found 
numerous small Diptera and Coleoptera in the flowers. 
Agathosma elegans, Cham . 
Abundantly visited by large Diptera, which, wandering 
through the umbellate flowers, become dusted with pollen. 
The flowers are protandrous, and the stamens ripen succes- 
sively just as in A. glabrata, Bart & Wendl., thoroughly 
described by Urban (Macleod, No. 557 ). 
Diosma ericoides, L . 
As described by T release (Macleod, No. 546) this seems 
to have exactly the same arrangement as Agathosma. 
Quivisia grandifolia, Scott Elliot , Ined. (Fig. 84.) 
In this genus the petals are united at the tip in the bud, and 
so enclose the tubular sheath formed by the united staminal
