Genus HOSACKIA Douglafi. 



This genus is included in Ihe old world ge- 

 nus Lotus by Greene, Coville A others, along 



ly SO throughout: leaflets 3 or less, ob- 

 long, obtuse, 1-2 mm. long: fl. single or 

 more rarely in pairs, short pedunculate, 

 2 mm long: calyx of equal length, the 

 teeth narrowly subulate, erect, J-^-J^ as 

 long as the tube: pod but sliglitly in- 

 curved, usually twice the length ot the 

 persistent calyx, i-seeded: seed dark 

 olive-green, 2>^ ram. long, slightly 

 curved. I take ple;;sure in dedicating 



with Syrmatium; we prefer to retain uU an- this delicate species to Mr Marion D. 



der Hosaelvia, though Syrmatium may well be Haydon, in return for his hospitality and 



treated as a distinct genus.
