54 MR. J. C. WILLIS ON THE 
attractiveness of the flowers to insects at a distance dependin 
solely upon their conspicuousness. 
The flowers are borne on very short peduncles, arising from 
the main axis of the inflorescence, which is hispid, bearing also 
a few glandular hairs. The calyx, of five green sepals, is similarly 
hispid and glandular, so that it would be very difficult for creeping 
insects to reach the honey. The funnel-shaped or somewhat 
campanulate corolla is barely longer than the calyx; its depth 
is usually about 8 mm. and width at the mouth about the same. 
The stamens, five in number, are very long and project 8-10 mm. 
beyond the corolla, upon whose base they are inserted. The 
anthers are versatile and contain large quantities of bright yellow 
pollen (fig. 8). The corolla gives off, at its base, ten processes of 
a curious bat’s-ear shape, one pair enveloping the lower end of 
each stamen (figs. 4 and 5, pr.). These project between the 
stamens to such a distance as almost to fill up the space between 
them and the style, as is seen in the cross section (fig. 4). They 
are attached to the corolla along a line close to the stamen, and 
their lower portions meet one another in the middle line above 
the stamen (fig. 5). These organs perhaps serve for the purpose 
of protecting the honey. The ovary is superior and bilocular, 
of flattened shape, ending in a style, which forks, at a height of 
about 2 mm. from the ovary, into two long branches, equal in 
length to the stamens. The extreme ends of these branches 
are stigmatic. Both ovary and style are provided with long 
hairs pointing upwards at an angle of about 45°. These are 
especially numerous on the end of the ovary, decreasing in 
number as we pass up the style, the last 6 mm. or so of which 
are glabrous. These hairs may very probably also assist in the 
protection of the honey, rendering it difficult of access to short- 
lipped insects. 
Below the ovary the receptacle is flattened out into a disk, 
on the side of which the corolla is inserted, while its upper sur- 
face, projecting beyond the base of the ovary, secretes honey, 
which accumulates in the base of the flower, protected, apparently, 
by the various arrangements above described. 
The stamens are bent inwards upon themselves in the bud, 
while the branches of the style are bent down outwards. When 
the bud opens the stamens straighten themselves out and stand 
nearly vertically, while the styles bend up just so far as to 
escape from the corolla and stand out almost horizontally over
