Many of the above specimens were previously erroneously idcntitied by me as 

 Rhododendron schadenbergii Warb., from whicli lliey ditler notaljly in tiie hirsute 

 ovary. The shape of the leaves is variable, and but few of the specimens are as 

 prominently acuminate as shown in tlie original figure, and they average smaller 

 than the measurements given in the original description. Tlie species is described 

 as having five stamens, but the figure apparently shows ten. the latter ninuber 

 agr<'eiiig with our specimens.

This species, as here interpreted, is closely allieil to A', kochii Stein, dilFering 

 notably in its glabrous ovaries. The type, wliicli 1 have seen in the Berlin 

 Herbariuni, is in \er\ poor c-oiidition. luiNiiig limi drieil out fioiu alcoholic 

 material, and conse(|Uenlly inucli shriveled, so thai an e\aniiualion of it was very 

 unsatisfactory: conse(piently my conception of the species has Ix-en bas(>d largely 

 on file (dalxirate original descrij)! ion. witli whicli the above specimens agiee fairly 

 wtdl. .Most of (he specimens jireviou^ly referred \>\ me to this species are, I 

 believe, referable to l,'liiidi>ili ndran Lorhii Stein.
