by supposing the cotyledons to be affixed in a peltate manner, and 

 united into a solid mass. 



Mr. Griffith was precluded from the further pursuit of the subject, 

 with reference to the development of the ovula and the more advanced 

 germination, by the departure of the Deputation for the investigation 

 of the Tea-districts of Upper Assam, of which he formed part.

The first of these contains the description of a plant found by 

 Mr. Griffith in a small island near Mergui, called Madamacan, and 

 which he has characterized under the generic name of Corysadenia, 

 but which is evidently the same with Dr. Blume's genus Illigera, pub- 

 lished in Europe in 1834, and consequently then unknown to the 

 author. In common with that botanist, and acting on a suggestion 

 of Dr. Wight, he indicates its near affinity to Gyrocarpus, with which 

 he suspects that it should form an order, to be called " Gyrocarpece." 

 He notices these genera as forming exceptions to a general rule 

 pointed out by Mr. Brown, that the ovarium of dicotyledonous 

 plants, when single, never adheres to the calyx. 



In the next paper, Mr. Griffith makes some additions to our know- 

 ledge of the genus Henslowia, which he characterizes as follows : — 



Henslowia, Wall. 

 Dioica. Mas : calyx suburceolatus, 5-partitus ; laciniis aestivatione apertis. 

 Corolla nulla. Stamina 5, calycis sinubus inserta ; filamentis per aBsti- 

 vationem introflexis, deinum erectis longeque exsertis ; antheris termi- 

 nalibus, 2-locularibus, loculis angustis distantibus longitudinaliter de- 

 hiscentibus. Ovarii rudimentum centrale, biloculare. Foem. : calyx
