08 DIl'TEKOCARPE.^ OF NEW GUINEA. 



sessile or sub-sessile, 1 iu. long, not locellate. Disk annular, 

 fleshy. Ovary l-celled, ^ inch long. Style more or less hirsute 

 above. Placenta marginal, longitudinal ; ovules numerous. Fruit 

 unknown. 



This, in common with one or two other species of the genus in 

 TroiDical Africa, is remarkable on account of the calyx-lobes 

 arising from the outer side of the calyx-tube just below its fi-ee 

 truncate enthe aiDex, thus leaving inside the calyx a short ring 

 about the middle of its limb. It differs from G. Jovis-tonantis, 

 Hn., in Oliv. Fl. Trop. Afr., iii, p. 101, n. 2, by its pentamerous 

 flowers and opposite not ternate leaves, as well as by other 

 characters ; it should immediately follow this species in the ' Flora.' 

 The general appearance of the flowering branches is much like 

 that of Randia nialleifera, B. et H. f., from which, however, it is 

 quite difl'erent with regard to the calyx-limb as well as generically 

 by the structm-e of the ovary. It is a handsome addition to the 

 previously known species of Gardenia, and would be weU worthy of 

 introduction for hot-house cultivation. I have much pleasure in 

 dedicating it to its discoverer, Mr. Kalbreyer, collector for the firm 

 of Messrs. Veitch and Sons, of Chelsea, who was successful in 

 detecting several novelties, the Orchids having been described 

 recently by Professor H. G. Reichenbach in the Eegensburg 

 'Flora.'

ON THE DIPTFROCARPE.E OF NEW GUINEA, WITH 

 REMARKS ON SOME OTHER SPECIES. 



By W. T. Thiselton Dyer, M.A., F.L.S. 



Grisebach, in his "Vegetation der Erde," has expressed the 

 conclusion that the flora of New Guinea is " thoroughly similar to 

 that of Borneo," and that in fact its vegetation is an eastern 

 extension of the general Indo-Malayan flora which is so splendidly 

 developed in its most characteristic features in that island. This 

 is, as Mr. Bentham has pointed out,''' a result quite at variance 

 with the distribution of animals as expounded b}^ Wallace. Such 

 a conclusion, Mr. Bentham justly also observed (p. 14), was " pre- 

 mature in the present state of our knowledge;" and he added, on 

 the authority of Sh Joseph Hooker, as an example of the want of 

 identity of the rcs^Dective floras, that no Diptcrovarpecc had been 

 found to the oast of Borneo. This remark was, of course, only 

 intended to apply to the Malayan Archipelago, since the family is
