NOTES ON ACMADENIA , B. AND W., WITH 
A DESCRIPTION OF ONE NEW SPECIES 
AND ONE NEW VARIETY 
By R. A. DUMMER. 
Acmadenia barosmoides, Dummer, in Journ. Bot. (1912), 221. This very rare 
plant was originally described by me from material at the British 
Museum, collected by Niven, one of the earlier botanical collectors, 
in Alpine stony places in Lange Kloof (Uniondale Div.). 
More recently Dr Marloth has collected this plant again but un- 
fortunately the three specimens in his Herbarium have no particulars 
as to locality and date of collection. These specimens do not quite agree 
with my original description in that the flowers are in pairs instead of 
being solitary, and the leaves more markedly glandular- denticulate, 
but I have no hesitation in assigning them to this species. As far as 
I am aware these specimens comprise the only dried material in S.A. 
Herbaria.

pedicellati, ramulos breves terminantes; calyx 2-5 mm. longus, trans-
