BALFOUR—NEW SPECIES OF RHODODENDRON. gl 
the lamina at the base. Franchet* has it: ‘‘ petiolo crasso 
I5 mm. longo, subtus glandulis consperso caeterum glabro,” 
but I do not find such restriction of glandular surface in our 
cultivated plants. These glands tend to disappear as the leaf 
oldens but their traces remain visible. In the text accompany- 
ing the figure of Rh. Souliei in the Botanical Magazine (1915), 
t. 8622, there is an obvious misprint—the Latin diagnosis and 
description gives the lamina as eglandular whilst the English 
description says glandular. It is true that on the upper surface 
of the lamina as it opens from the bud there is a sprinkling of 
stalked red glands, but they have disappeared from the fully 
expanded lamina, which is eglandular both above and below. 
In the calyx characters there is much difference from Rh. Souliet, 
for we miss in Rh. callimorphum the large membranous gland- 
margined lobes of Rh. Souliei and find only small unequal 
glandular projections as is the case in Rh. Williamsianum, Then 
the style in Rh. callimorphum has long-stalked glands at the 
very base only and is not glandular throughout as in Rh. Soulter.
