stalked small bud of the shape of a pin’s head. The style ter- 
minates in a two-lobed stigma and is only rarely disturbed. 
Deviations: 
lo Tetramerous flower. Calyx-lobes 4, corolla-lobes 4, of 
which the two smaller ones are unstriped, the two larger 
ones are marked with three dark stripes. Between these the 
tube is split up a long way downwards (Fig. 314). One of the 
margins of the fissure is bent inwards as far as the base of the 
lobe; along this margin and grown together with it, runs up 
a stamen with a disturbed anther (compare fig. 31> normal 
anther with fig, 3l¢ abnormal anther). 
Moreover there are three staminodes. 
2° Hexamerous flowers. The two inferior lobes have each 
of them three dark stripes; alternating with these two and 
the adjoining ones, we find three normal stamens, besides 
three staminodes. ? 
3° Double flower (Fig. 314). Calyx-lobes 9, corolla-lobes 9, 
the three inferior ones (a, 4, c) with three dark stripes, the 
two adjacent ones (d, 2) with a small stripe each; e and 4 
unstriped; the two superior ones (¢, g) each with two dark 
stripes, f with an additional little stripe. With ¢ and a, a and 
6, 6 and ¢, ¢ and d, f and g normal stamens alternate; the 
other four are sterile. Two separate styles with fairly normal 
stigmas; a little downwards each style bears a branchlet bent 
downwards. The peduncle is flat, slightly grooved in front 
near the flower; at the back under the calyx in the middle 
there is a little bract, which runs a little way downwards so 
resembling a ridge. This case is a consequence of synanthy> 
predisposed by the not uncommon appearance of two flowers on 
one stalk. 
4° Pentamerous flower (Fig. 31°). Two lobes with three dark 
stripes; between a and 4, 4 and c, normal stamens; between 
a and e, ¢ and d staminodes. Nothing between d and e. 
Calyx 4-dented. 
5” Pentamerous flower. Calyx 5-dented. Three dark stripes 
on each corolla-lobe, 5 fertile stamens.
