On the Sea-Coast in all the provinces. Distrib. Tropics generally. 

 Tlie antliers of this species are two-celled and dehisce by upward-openino- 

 valves. Those of the genus Hernandia are also 2-celIed, but dehisce by valves 

 which open laterally. In habit and form of leaves Gyrocarpus much resembles 

 Hernandia ; whereas it is quite au aberrant form amongst Coinbretacex, as is also 

 Illiyera.

No. 10. 

 I had hoped in the present contribution to have completed, for 

 these Materials, my account of the whole of the remain infr Natural 

 Orders of Galycijloras. This hope has, however, been frustrated by sick- 

 ness. I have decided therefore to offer now to the Society the account 

 of the five Orders which I have been able to elaborate ; trusting, at 

 some time in the near future, to deal with the remaining Orders of 

 the Class. Following the sequence adopted by Sir Joseph Hooker in 

 his Flora of British India, those treated of in the present paper 

 come to be numbered as below ; Nos. 48 Lythracese, 49 Onagraceas, 50 

 Samydaceae, 52 Gucnrbitacese, and 56 Araliacese. And those which re- 

 main to be described would be Nos. 46 Myrtace^e, 47 Melastomacese, 51 

 Passijloracede, 53 Begoniaceas, 54 Ficoidese, 65 Umhellifer^e, and 57 

 Gornaceae. After finishing tiie Calycijiorae, I hope, in collaboration with 

 my friend and successor Dr. D. Prain, to describe the families which 

 are embraced in the gamopetaloas and apetalous groups.
