186 DR. HOOKER ON SOME REMARKABLE ARISTOLOCHIAS 
hereafter to be described, they are ten or twelve as in the Malayan genus Thottea, 
which they further resemble in the 3-lobed perianth, but from which 4. Goldieang 
differs in the anthers being sessile, inserted in a single series, and in the 6-celled ovary; 
2. the number of styles or divisions of the column, which are about twelve, each bifid, 
the highest number in described species being six. In habit, size of flower, and colour 
it resembles the American A. gigantea, Mart. & Zuce., but differs entirely in the form of 
the perianth and structure of the column. 
Another novel point in this flower, but of which more information is wanted, is the 
swollen and apparently glandular apices of the stigmatie erura. The true position of 
the stigmatic surfaces is, in other species, marginal and decurrent on the lobes ; and if 
so in this, it is possible that the glands may be secretory organs, whose object may be to 
attract insects to the column, their agency being obviously essential to fertilization—or, 
as is the case with the rostellum of some orchids, to aid the transport of pollen by sup. 
plying the viscid matter which adheres to the limbs of insects. 
The colour of the flower is, according to description, violet, more or less variegated 
with yellow and red-purple; and the odour, according to the Bishop of Sierra Leone, 
resembles that of decaying fungi.
