378 Dr Wallich on the Progi^ess of Botany in Bengal. 
veteran collector employed for the Botanical Garden in 
Sylhet. ^ 
A Streptopus. 
Several species of Carex, of which genus there are very few 
in India. 
An Andromeda, with minute leaves like an Erica, which Dr 
Wallich calls cuyressformis. 
Some Potentillas. 
A third species of Rhododendron, probably one of those 
mentioned by Dr Hamilton in his Account of Nepal. 
A Kibes. 
Several species of Pedicularis and Fumaria, in addition to 
those found near Kathmandu. 
Some species of a new genus of the Bignonaceae, which Dr 
Wallich intends calling Didymocarpus, and which is near- 
ly allied to the Incarvillia, of which several species are al- 
so found near Kathmandu. This genus may be distin- 
guished, Staminibus 2 sterilibus; ovario pseudo-quadri- 
loculare ; capsula lineari elongata pedicellata bipartibili ; 
singula biloculari marginibus dehiscente ; seminibus mi- 
nutis nudis insertis valvularum interiorum marginibus li- 
beris involutis; corollae labio superiore brevissimo infe- 
riore elongate. 
The plants of this genus have a considerable affinity to the 
genus Sesamum ; are herbaceous, and somewhat fleshy, and are 
mostly covered with short hairs, interspersed with minute resinous 
dots, occasioning a degree of viscidity. Their stem, when they , 
have any, is generally undivided ; the peduncles are slender ; the 
flowers are generally show}?', purple, and very tender, which ren- 
ders the examination of dried specimens very difficult : the plants 
abound in a resinous fragrant exudation, and among the natives 
are called by the generic name Kumkuma, yielding a drug of 
this name. Their primordial leaves dried, form the drug called 
Kani Govindhi. These drugs are in high esteem, and are used 
as a sacerdotal offering by the Brahmans, and also as a perfume 
by the Hindu ladies. Dr Wallich has only been able to rear 
one species in the Botanical Garden : the others all died shortly 
after their introduction, the heat probably being too great.
