Most distinct pyieiies: Noteworthy are :—The coaetaneous 
flowering immerses the flowers amongst the foliage. Glabrous 
glaucous prune-coloured twigs scantily puberulous epilose. The 
perulae and buds are very distinct, specially the paucity of hairs 
on the perulae. The leaves glabrous above (I saw one or two hairs 
on a young leaf). The red veins of young leaf. Leaves at first 
ei below. Underleaf scales distant about 5 to a sq. mm.
