calyces about i/ß ioch long, not angular. Petals measuriug nearly i/s 

 inch in length. Stamens uniform ; filaments very narrow , but flat ; 

 anthers resembling those of Ochthocharis and Veprecella. about i/s 

 inch long, basifixed, slightly recurved upwards, somewhat retuse at 

 the base. Style slender ; stigma very minute, spherical. Berry about 

 1/3 inch long and broad. Placentae soft, strictly axile, covered with 

 seeds from the base to the summit. 



This beautiful and remarkable plant is dedicated to J. H. Maiden, 

 Esq. , who , notwithstanding impaired health , undertook the onerous 

 duties of Hon. Secretary of the Australian Geographical Society in 

 Sydney, sharing in all the toil for arranging and fitting out Captain 

 Everill's Expedition. 



I have not ventured to remove this plant from the genus Medinilla, 

 although the form and dehiscence of the anthers bring it near Pter- 

 nandra, from which the truly axile not basal nor parietal placentation 

 separates it. The main obstacle to leaving our plant in Medinilla 

 consists in the want of anterior basal appendages or protrusion of the 

 anthers ; indeed they are very short in the original M. rosea ; as regards 

 its rameal inüoreacence, distant from the leaves, it approaches M. radi- 

 cans, diifering from that plant in the obliteration of petioles and ped- 

 uncles , in the not verticillate leaves with a very peculiar nervature, 

 and alfjo most particularly in the form of the anthers. Some affinity 

 to M. Malabarica also exists. 



There is however no objection to putting our plant into Pachy- 

 centria, if that genus must be kept permanently separated from Medi- 

 nilla. The inflorescence removes the present species already from all 

 Pachycentrias hitherto known.J
