A rather small plant. Stem about ■30- '48 mm. thick. 

 Internodes 2-4 times the length of the branchlets. Whorls 

 of usually 8 primary branchlets with about double that number 

 of smaller secondary branchlets in two series, the one above 

 and the other below the primary branchlets- Primary branch- 

 lets 2-3 times divided, the primary rays ^-f- the total length of 

 the branchlets. Eays at the first forking 7-10 (of which 1-3 are 

 usually simple); at the second forking 4-7, of which 0-2 are 

 again divided into 4-5 quaternary rays. Ultimate rays 2-celled, 

 apical cell •09--14 mm. long, •03-*045 broad at the base. 

 Secondary branchlets usually one above and one below each 

 primary branchlet, those of the lower series usually once or 

 twice divided into 4-6 rays, those of the upper usually once
