W. H. Harvey on two new Genera of Passiflorecc. 421 



cimens from Mr. Zeyher, he is satisfied it should be referred to 

 Passiflorece, in which Dr. Arnott agrees, but remarks, that if 

 this and Ceratosicyos and Paschanthus and Modecca be united 

 to Passiflorea?, the definition of the order will require to be 

 modified and enlarged. The parts of the flower in Acharia, 

 Mr. Harvey observes, vary from 3 to 4 ; and it may be stated, 

 that what Dr. Arnott calls involucral bract eas, Mr. Harvey 

 considers a calyx.

As the learned Professor Nees von Esenbeck has, in the 

 work above quoted, given a full generic and specific descrip- 

 tion of this plant, we shall here content ourselves with men- 

 tioning the particulars in which Mr. Harvey finds a differ- 

 ence from what is related by the German author. " The 

 glands," Mr. Harvey remarks, a are outside the staminal cup, 

 as in all the order, and the stamens are always as numerous 

 as the clefts, sometimes, as represented in our figure, com- 

 bined in pairs irregularly. I have dissected off the ring of 

 the stamens, leaving the glands still attached to the calyx, a 

 pretty good proof that I am not deceived. The parts are 

 often only four, as in Acharia. The glands are surely in both 

 flowers abortive stamens, exactly similar to those of Modecca 

 and the rays of Passiflora."
