148 REVISION OF THE NATURAL ORDER BIGNONIACE^. 



which he founded the genus Haussmannia. A close study of the two 

 genera convinces me that they are identical, and must retain the oldest 

 name, Nt/ctocalos. As far as I am aware, there are at present four 

 species known, viz. N. brunsfelsicpflorum, N. cuspidatiim (previously 

 described by Blame from sterile specimens, as Tecoma cuspidatd), 

 N. Thomsoni, from Assam, and N. jiicundam, from Queensland. The 

 two former species differ from the two latter by having 5 fertile sta- 

 mens, whilst the latter have only 4 fertile and 1 sterile one. Dr. 

 Hooker, in speaking of N. hrmisfelsl(Bfiorum (Bot. Mag. t. 5678), 

 says, that he should like to see a confirmation of the five fertile 

 stamens attributed to it. But after a second species, with 5 fertile 

 stamens, has come to light (both figured by Miquel), there can be 

 no doubt about the correctness of the original description of the sta- 

 mens given by the founders of the genus. The same thing occurs in 

 Neiobouldia, where we have a species with 4 and another with 5 fertile 

 stamens ; and a similar case in Diplanthera, E. Br. (Bultoena, F. 

 Muell., Deplane/tea, Bur.), where we have, in D. Utraphylla and D. 

 Sancana, 4 fertile stamens and no rudimentary fifth, and in D. spe- 

 eiosa. Seem. (J)eplancJkea speciosa, Vieill.) 4 fertile stamens with a ru- 

 dimentary fifth.
