There is some doubt as to the earliest specific name for this species. Robinia 

 mitis Linn. (1763) was based in part on Cytisus pinnatus Linn., of tlie first 

 edition of the "Species Plantarum," but in his consideration of Robinia mitis, 

 Linnaeus excluded tlie first reference, given in the first edition under Cytisus 

 pinnatus, Pluk. phyt. 104. /. 3. I have been unable to check 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 4^0 is apparently typical 

 P. grandifolia Zoll. & ilor.
