Rh. polylepis or Harrovianum. This appears to be a poor thing, very 
upright in habit, flowers small, purple. It flowers in April, and seems 
quite hardy. 
Rh. longistylum seems very near to micranthum. The flowers in small 
trusses, white, and very early in February. The habit and leaf are nice, but the 
early flowering makes it unlikely that it will be a successful plant for gardens. 
Rh. Yunnanense and Rh. chartophyllum PRiECOX are apparently much 
on the same lines. They are extremely floriferous, the forms varying from mauve 
with crimson spots to white with crimson blotch. Plants upright, fairly rigid 
and semi-evergreen. They are at their best in May, and undoubtedly are a great 
acquisition. They seem to be more successful in the sun than many 
rhododendrons, but are free growers anywhere. 
Rh. Davidsonianum is closely allied to the above, but is nearly evergreen, 
and the mauve bell seems to be rarely spotted or blotched. 
Rh. Augustinii flowers are larger than Yunnanense, and vary from pale 
mauve to dark lavender purple. Some of the flowers are most attractive, but 
perhaps want careful placing. The plant is evergreen, and for habit is much on 
the lines of Yunnanense, but not quite so rigid. It flowers in May, and good 
forms are well worth growing. 
Rh. oreotrephes (see illustration in R.H.S. Journal, for October, 1916, 
p. 33). This again is a good garden plant. The mauve flowers are not so striking 
as the remarkable glaucous foliage which in some of the forms is quite unusual. 
The habit of the plant is good. 
Rh. hanceanum is a low straggly evergreen shrub of no great merit. The 
flowers, of a poor ivory-white or dull yellow with pink tinge, are somewhat 
absorbed by the protruding stamens. I have heard of a good yellow form, but I 
have not seen one. 
Rh. trichocladum. Deciduous. The small yellow flowers are not in any 
way remarkable, but the grey hairy leaf (often with crimson blotches), is veiy 
attractive in the young state. 
Rh. moupinense flowers in February, too early to be a valuable plant, but 
if it escapes frost it is most beautiful. The flowers are scented and vary ver}'^ 
much in colouring. Some forms have almost crimson buds which fade to nearly 
white, others are white with yellow, crimson, or even purple spots. The plant 
is hardy, but of a poor habit and very brittle. 
Rh. ovatum is quite one of the most attractive of the small flowered 
rhododendrons. The flowers in my experience are pink with small spots, but I 
believe there are other forms. The evergreen leaves and the young growth are 
both very fascinating. The habit is good. I believe it was introduced by 
Fortune, but it had become so scarce, and it is so attractive that its 
re-introduction is most welcome.
