518 D. Prain — More 'additional species of Labiatae. [No. 2, 



long-. "6 in. wide ; valves thinly coriaceous puberulous, not sinuate between the 8-10 

 ovate seeds which have long axes parallel with sutures, '7 in. long, '4 in. wide, com- 

 pressed ; testa thin crustaceous. 



A very distinct species, nearly related to P. bigeminum Mart., but with much 

 larger flowers and with a pod that differs markedly in being long stalked. 



Addenda. 



24. CARAGANA Lamk. 



56. Caragana decorticans Hemsl. in Hook. Icon. Plant, t. 1725. 



When arranging the Caraganas of the Calcutta Herbarium the writer unfortu- 

 nately overlooked the fact that his friend Mr. Hemsley had already detected Dr. 

 Aitchison's misidentification of this plant with C. ambigua and had published a des- 

 cription and figure of it under the above name, which must therefore replace the 

 name Caragana Aitcliisoni, used on page 372. 



75. PACHYRRHIZUS Rich. 

 Pachyrrhizus angulatus Bich. 



Professor Oliver has recently given an excellent figure and description of this 

 well-known plant (Hook. Icon. Plant, t. 1842). In the same work (t. 1843) is also 

 given a figure and description of the S. American and W. Indian P. tuberosus Lamk., 

 which is closely related to P. angulatus and is best distinguished by its almost entire 

 leaflets and its larger broader pods. It has recently been introduced to Ceylon ; its 

 pods make an excellent vegetable; its seeds are poisonous. 



P. tuberosus is related to P. angulatus exactly as Phaseolus Mungo is to P. 

 radiatus and as Dolichos lignosus is to D. Lablab. 



Novicise Indicae XVI. More additional species of Labiate. — By 



D. Prain. 



[Received May 26th ; Read June 2nd, 1897.] 



Since the writer presented descriptions of some additional species 

 of this natural order to the Society, six and a half years ago, a few 

 others have come to light that are additions to the Indian flora ; des- 

 criptions of these, drawn up after the style of the Flora of British 

 India are accordingly offered in the hope that they may be of use to 

 members who use that work in the field.
