There is some doubt as to the earliest specific name for this species. Robinia 
mitis Linn. (1763) was based in part on Gytisus pinnatus Linn., of the first 
edition of the “Species Plantarum,” but in his consideration of Robinia mitis, 
Linnaeus excluded the first reference, given in the first edition under Gytisus 
pinnatus, P’luk. phyt. 104. f. 3. I have been unable to cheek this reference to 
Plukenet, and consider it safer to adopt the second name proposed by Linnaeus. 
B. Daydon Jackson, Esq., secretary of the Linnean Society, has kindly examined 
the specimen in the Linnean herbarium labeled by Linnaeus Robinia mitis, and 
informs me that it an undoubted specimen of the plant usually named Pongamia 
glabra, consisting of a flowering branch in a young state, with a single 
detached pod. 
The material cited above includes the typical form, with medium-sized leaflets 
and flowers, and also apparently the form described by Zollinger & Moritzi as 
Pongamia grandifolia, with larger leaflets and larger flowers. I find, as Prain 
has already noted, a great number of intergrading forms, and do not think that 
the latter can be distinguished by any constant character or set of characters. 
Among the numerous specimens cited above, Ahern 420 is apparently typical
