110 THE VICTORIAN NATURALIST. 



I had the satisfaction of finding that ten of them were new to 

 science. I would recommend Melbourne collectors to search 

 well about the Yarra, Dandenong, You Yangs, Mount Macedon, 

 Riddle's Creek, Lancefield (Deep Creek), Sunbury, Gisborne, 

 etc. September, October, and November are the best months 

 for the dry localities, and December, January, and February for 

 the higher mountains and moist forest country. Mosses may be 

 found in certain localities throughout the year, but in winter, 

 except in rare cases, they are not in a fit state for detailed 

 examination, having lost both the calyptras and operculums 

 parts, which are sometimes of great value in deciding specific 

 distinctions. 



How to Colled Them. — A moss, when complete, has roots, 

 stem, leaves, a seta oi fruit stalk, sporangium or capsule, oper- 

 culum, and calyptra. Carry a knife or chisel, and dig them up 

 by the roots. Secure, if possible, specimens in all stages of 

 development. The inflorescence of mosses is polygamous, 

 moncecious, or dioecious. In such cases specimens of both 

 male and female must, if possible, be secured. The females 

 bear the urns. Have a magnifying glass and plenty of paper. 

 Separate the species on the spot if you can. Some mount the 

 specimens on cardboard ; others keep them in nicely-folded 

 papers of a uniform size. I prefer the latter plan. When you 

 wish to examine dried specimens place them in tepid water for 

 two or three minutes, then dry between two sheets of blotting 

 paper. By this means the leaves will expand, and the plant 

 will assume its natural shape as when growing. 



DESCRIPTION OF AN HITHERTO UNRECORDED 

 RHODODENDRON FROM NEW GUINEA; 



By Baron von xMueller, K.C.M.G., M. & Ph.D., F.R S. etc. 



Rhododendron Carringtoniae. 



Tall ; leaves moderately large, very firm, almost sessile, 

 mostly in whorls of few, usually obovate, slightly recurved 

 at the margin, dotted particularly on the under-page with minute 

 scalelets, otherwise glabrous ; their carinular venule very pro- 

 minent, the secondary venules somewhat costular and anasto- 

 mosing with the likewise elevated tertiary venules; flowers few 

 together terminally on short stalklets ; bracts clasping, roundish, 

 glabrous, dorsally somewhat beset with minute scalelets, very 

 much shorter than the inflorescence ; calyx reduced to an 

 oblique very narrow almost entire membrane ; corolla com- 

 paratively long, white, outside dotted with scattered scalelets, 

 otherwise glabrous, inside towards the middle and base
