THE VICTORIAN NATURALfsT. Ill 



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 somewhat 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, narrowlv 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 eleva- 

 tions from about 6000 to 7000 feet ; Cuthbertson and Sayer. 



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

 length of 3 inches, but often shorter. Tube of the corolla to 

 2^ inches long, but only about ^ inch broad; lobes measuring 

 i — i- inch in length. Style gaining fully 2 inches in length. 

 Fruit about ij inches long, slender. 



This quite recently discovered member of a noble genus of 

 plants is dedicated to Lady Carrington 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. Arfaki- 

 anum 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. Hatamense, it is easily 

 distinguished by the much more prominent venulation of the 

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

 cylindric anthers and not glabrous disk. 



Among other congeners the species now recorded afproaches 

 as regards the proportionately great length of the corolla-tube 

 to R. longiflorum, which species however has a red corolla, 

 anthers of diff'erent 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 

 jast described ; but its calyx produces two dijnticles, 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
