Rhododendron Carringtoniae. 



Tall ; leaves moderately large, very fii-m, almost sessile, mostly in 

 whorls of few, usually obovate, slightly recurved at the margin, dotted 

 particularly on the under-page with minute scalelets, otherwise gla- 

 brous ; their carinular venule very prominent, the secondary venules 

 somewhat costular and anastomosing 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 comparatively 

 long, white, outside dotted with scattered scalelets, otherwise glabrous, 

 inside towards the middle and base copiously beset with short hairlets ; 

 its tube very slender, almost cylindrical, somewhat curved ; its lobes 

 five , from obovate to orbicular and slightly cuneate , several times 

 shorter than the tube; stamens ten, partly attaining the length of the 

 corolla ; filaments much beset with minute hairlets ; anthers linear- 

 cylindrical, slightly clavate, minutely bidenticulated ; style long, towards 

 the middle and base as well as the whole ovulary invested with some- 

 what spreading hairlets ; stigma short- and blunt-lobed, surrounded by 

 a narrow cover ; disk densely ciliolated around the summit ; fruit rather 

 long, much attenuated into the base, narrowly ellipsoid-cylindrical, but 

 pointed, bluntly five-angular, clothed with copious scalelets and also 

 short hairlets; appendages at the extremities of the seeds very narrow. 



On almost inaccessible declivities of Mount Obree, at elevations 

 from about 6000 to 7000 feet ; Cuthbertson and S a y e r. 



Height of the plant to about 10 feet. Leaves attaining a length 

 of 3 inches, but often shorter. Tube of the corolla to 2V2 inches long, 

 but only about V, inch broad; lobes measuring V3 — V2 i^^ch in length. 

 Style gaining fully 2 inches in length. Fruit about l'/j inches long, 

 slender. 



This quite recently discovered member of a noble genus of plants 

 is dedicated to Lady C a r r i n g t o n in also phytographic appreciation 

 of the interest, evinced by her Ladyship in the floriculture of the 

 colony, over which the Right Honourable Lord Carrington at 

 present exercises vice-regal administration. 



Among Papuan species this new one differs from R. Arfakianum in 

 leaves less attenuated towards the base, shorter petioles, flowers fewer 

 together on very short pedicels, calyces not denticulated, corolla of 

 greater length and white colour, proportionately much shorter corolla- 

 lobes, narrower anthers and not almost glabrous style. From R. Hata- 

 mense, it is easily distinguished by the much more prominent venu- 

 lation of the leaves, the whiteness of the corolla, longer coroUa-tube, 

 cylindric anthers and not glabrous disk. 



Among other congeners the species now recorded approaches as 

 regards the proportionately great length of the corolla-tube toR.longi- 

 floi'um, which species however has a red corolla, anthers of diflferent 

 shape and a much shorter style. Mr. Sayer brought from Mount 

 Obree another Rhododendron, occurring at an elevation of about 7000 

 feet; this plant resembles in disposition as well as form and texture 

 of its leaves the species just described; but its calyx produces two 

 denticles, the corolla is red and has a much shorter tube, the anthers 

 are broader and of less length, the ovulary is not attenuated towards 

 the base, beset with scalelets only and as well as the style much 

 shortei", while the disk is glabrous ; this Rhododendron is closely allied 

 to R. Lochae, from which it is mainly separated (unless also by its as
