N.E. Upper Burma. Chimili cliffs. Alt. 12,000-13,000 ft. 
A low almost prostrate cushion in the high alpine granitic 
precipices opposite the Chimili Pass. Flowers clear yellow, 
ut of no particular charm. Farrer. No. 938. Just coming 
into bloom May 18, 19109. 
N.E. Upper Burma. A western buttress of Imaw Bum. Alt. 
10,000 ft. A beautiful dwarf. Epiphytic on an old fir-tree 
where it formed a compact cushion high up. Flowers pale 
lemon-yellow with orange-red stamens. Leaves silver-green 
underneath. Kingdon a No. 3095. May 27, 1919. See 
No. 3196. Also cf. No. 
N.E. Upper Burma. Valley of the Chaung-maw-Lka. Alt. 
8000 ft. Dwarf shrub forming a sort of heath on a large mossy 
boulder in the river bed. Other rhododendrons, a fir-tree, etc., 
growing on the same boulder. Kingdon Ward. No. 3196. 
June 6, 1919. Same as No. 3095. 
A representative in N.E. Upper Burma of the Mekong- 
Yangtze species Rh. megeratum, Balf. f. et Forrest (see p. 140). 
They are microforms of one type. This southern form has 
altogether a dwarfer habit as it is described and at times is 
epiphytic and has elliptic smaller leaves. The most conspicuous 
difference is seen in the calyx the lobes of which glabrous in 
Rh. megeratum are crowned by long bristles in Rh. tapeinum. 
In the dried specimens this Burmese plant is hardly so 
attractive as is the northern species in Forrest’s specimens, 
yet I should expect it to be quite a delightful plant for the rock ° 
garden and to this Kingdon Ward’s comment, “ a beautiful 
dwarf,’’ may be cited in support. To Mr. Farrer, however, 
the flowers did not appeal as of any “ particular charm.” 
Rhododendron timeteum,* Balf. f. et Forrest.+ 
A shrub barely 2 m. high at most with short yearly growths 
which interlace and evidently form a compact bush. Twigs of 
* tiyuntéoc, to be honoured—in allusion to its value as a garden plant.
