sac, which may be found unaltered in the placenta of the ripe fruit. 

 Whether the first cells, constituting the rudiments of the part in 

 which albumen is suljsequently dejDosited, are derived from the boyau 

 or from the embryonary sac, Mr. Griffith states, that he has not 

 been able to determine ; but he imagines that they are derived fi'om 

 the boyaii. He adds, that if his views of the seed of Loranthus being 

 derived from the boyau solely be correct, Osyris is intermediate be- 

 tween Loranthus and Santalum ; and intimates his intention of send- 

 ing, on his arrival at Calcutta, a Supplement to his paper on Loran- 

 thus, published in the Society's Transactions.

In his Monograph in the Wernerian Transactions, Mr. Brown re- 

 ferred the genus Cryptolepis, which he there established, to Apocyneos, 

 placing it next to Apocynum, and in this he has been followed by all 

 subsequent writers ; but Dr. Falconer states that it has the whole 

 stigmatic apparatus of Asclepiadeas, with granular pollen as typically 

 developed as in Cryptostegia or any other of the PeriplocetE, although 

 in a less considerable degree of evolution. He regards it, however,
