BALFOUR—NEW SPECIES OF RHODODENDRON. 107 
style stout glabrous expanding into a conspicuous lip below the 
lobulate stigma. Capsule cylindric about 2 cm. long 7 mm. in 
diameter shallowly grooved more or less glandular or with traces 
of glands sticky more or less enclosed by the enlarged hardened 
calyx, dehiscing by 5 valves from the apex style often persistent 
after dehiscence. Seeds pale-coloured elongated about 3 mm. 
long about .5 mm. in diameter with a chalazal and a funicular 
fringed crest.

A fine species from that home of good things, Ka-gwr-pw. 
The plant has more than one special feature of interest. 
In the first place, the foliage is noteworthy—thick fleshy 
leaves the outline of which is exactly that of a jargonelle pear 
and with an ash-grey upper surface which is due to a thin pellicle 
of wax covering it everywhere. A little benzole or other solvent 
placed on the surface removes the wax and exposes the coloured 
leaf-surface beneath, which is also of interest. In most of the 
older leaves the surface is green but the veins are more or less 
reddened; the young leaves are red all over and this red 
colour may be retained more or less in the older leaves and 
show on removal of the wax. Another feature of the foliage 
deserves notice. The young leaves on the annual shoots elon- 
gating after flowering and from below the inflorescence in all the 
specimens available for examination produce leaves much smaller 
than those on the older branches and more oblong in character. 
No one of the lateral twigs on branches now passed into fruit has 
leaves of the size and shape of the mature leaves on the flower- 
bearing shoots, and we must assume therefore that the growth of 
the leaves is much prolonged and that only towards the end of 
the season of each annual shoot do its leaves take on their adult 
character. 
Then in the flower we have to note that the ovary is densely 
glandular but the style is wholly glabrous. The plant does not 
leave us in doubt about its affinity. It is one of the Thomsoni 
series using that term in its widest sense as I explained it in 
a previous number of these Notes.* This glandular ovary
