At Plate 4336 of this work a Rhododendron is figured 
under the name of &. javanicwm, which is, I think, unmis- 
takably the R. Teysmanni, Miquel (Fl. Ind. Bat. Suppl. 
p- 201 and 585, and Ann. Mus. Lugd. Bat. vol. i. p. 42, 
t.1). It differs from &. javanicwm in the more robust 
habit and more numerous very much larger flowers of a 
citron-yellow colour, with broad corolla-lobes ; to which 
character Miquel adds that of the ovary being covered with 
white pubescence without lepidote scales; but I find no 
material difference in this respect, and it is quite possible 
that Teysmanni is a variety of javanicum, though for horti- 
cultural purposes a most distinct one. The only published 
plate of the true R. javanicum is that given by Bennet in 
the work quoted above, and he both figures and describes 
the ovary as pubescent, and says nothing about scales; the 
flowers he represents as bright red, but I suspect the 
colouring is not dependable. &. Teysmanni and javanicum 
have been found both in Sumatra and Java, according to 
specimens from the Dutch Herbaria. Of the other Sumatran 
species of the genus, R. citrinum is figured at Plate 4797, 
Lt. retusum on Plate 4859, R. malayanum, Plate 6045, and
