294 ILLUSTRATIONS OF THE BOTANY OF [ Bignoniacee. 
Didymocarpus venosus and Chirita diaphana, nob., attain the highest limits, being found 
on Tuen, between 7,000 and 8,000 feet of elevation. 
The plants of this family are watery in nature, and possessed of little sensible 
properties ; but one species, Didymocarpus aromatica, is stated by Dr.Wallich to be 
used as a perfume and an aromatic drug, and called by the natives kumkuma and rani- 
govindhi.

Hab. This elegant plant is found, with Chirita bifolia, covering the rocks in the rainy season in the 
Himalayas; v. swpra. Though already figured by Dr.Wallich, it has been repeated in this work at his 
particular request, and being so conspicuous a feature of these mountains at one season of the year, 
could not well be omitted in a work specially dedicated to the illustration of their Flora; but this 
figure also fails in doing justice to the extreme beauty of the plant. I have referred the genus to 
Cyrtandracee, in conformity to the opinion of Mr. Bentham, who has undertaken the monography of 
that family. : | | 
121. PEDALINE. 
The Pedalineé of Mr. Brown, Sesamee of some authors, are so closely allied to both 
the preceding and the following order, that Dr. Lindley states, Nat. Orders, p+.237, 
that “the three might be re-united without much inconvenience ;” they are distinguished 
from Cyrtandracee by their woody placentz and hard, stony fruit; and from Bignoniacee 
by their wingless seeds, but like both are found only in tropical parts of the world. 
The genera found in India are Pedalium and Sesamum, both probably peculiar to the 
country ; but the latter is so much cultivated, as to have become distributed in different 
countries of Asia and Africa. S. prostratum is found on the coasts: several other 
species are enumerated ; but those which I have seen, though permanent, appear only 
varieties of one species. One is called kala til, from the blackness of its seeds, and isa 
larger plant than the white-seeded plant, called suffed til, which is not so common as 
the other in Northern India. These plants are every where extensively cultivated in 
India for the excellent oil yielded by their seeds, and known by the names of Sesamum 
and Gingilie oil, meetha tel and til ke tel of the natives. By a little management it may 
be made to look and taste nearly as well as olive oil, for which it is frequently substi- 
tuted. The leaves, like those of Pedalium murer (gohhroo-dukhunee) are mucilaginous, 
and the meal like that of other mucilaginous seeds, as linseed, is esteemed for poultices. 
122. BIGNONIACER. 
The Bignoniacee, in addition to their other alliances, have also a close one to Acan- 
thacee, from which they are distinguished by their winged seeds. Though generally 
arborescent, the order also contains herbaceous genera, as Eccremocarpus, Calampelis, 
and
