3839, and a specimen of doubtful provenance bearing the number 
301, which Miiller has been able to assign to Krebs. This latter speci- 
men Miiller transfers to A. peduncularis, var. psilogyne, Mill. Arg. 
But Miiller’s modification of A. Zeyheri by no means ends here, for 
he treats A. Zeyheri, Baill. (1863) as merely a variety, var. glabrata, 
of an enlarged A. Zeyheri, Miill. Arg. (1864), the other variety of 
which, var. pubescens, is in intention identical with the original 
A, peduncularis, EH. Mey. (1843). There is no clue in the earlier 
account given by Miiller in Linnaea, vol. xxxiv., to the idea under- 
lying this arrangement. Apparently as an afterthought, a character 
is added in the account given in the Prodromus which might have 
served to differentiate A. Zeyheri, Miill. Arg., hardly of Baill. from 
A. peduncularis, Miill. Arg., not of E. Mey and hardly of Meisn., 
had it been constant. This character is that in A. Zeyheri, as 
widened by Miiller, the flowers are monoecious, whereas in A, 
peduncularis they are dioecious. It is true that in some, but by no 
s all, of the specimens actually included by Miiller in his 
A, Zeyheri, var. pubescens, the flowers are monoecious. But there 
is not a single example of Zeyher, 3839, which is all that Miiller 
has left in A. Zeyheri, var. glabrata, in which the flowers are 
monoecious. In his choice of the varietal name glabrata to 
designate Baillon’s original A. Zeyheri, Miiller has been singularly 
unfortunate. The name was selected under the impression that the 
plant in question is A. peduncularis, var. glabrata, Sond. e know, 
The same entanglement marks Miiller’s treatment of his A. 
Zeyheri, var. pubescens. The specimens collected by Masson, 
Krebs, and Ecklon and Zeyher, which Baillon refers to A. pedune- 
ularis, var. genuina, are identical with those collected by Drége, 
which are referred to A. Zeyheri, var. pubescens. The latter are 
© means invariably monoecious, the former by no means 
invariably dioecious, and the idea that Meisner was in error when 
he identified with Meyer’s plant so named a_ species from Natal 
which he deseribed for Krauss as A. peduncularis, is without 
foundation. At the same time A. Zeyheri, Baill., remains a per- 
fectly valid species, but one with which A. peduncularis, var. 
glabrata, Sond., is not synonymous, 
If the treatment accorded by Miiller to A. Zeyheri, Baill., leaves 
something to be desired, this is more markedly the case as 
regards the treatment of A. peduncularis. In this species, Miiller 
has recognised as many as seven varieties :—(a) caperonioides ;. 
(B) genuina ; (y) psilogyne ; (8) crassa ; (<) punctata; (2) du- 
lifolia ; (n) angustata. Of these a, caperonioides is a valid species, 
A. eaperonioides, Baill. (1863), the earliest name for which, A. pe- 
 duneularis, var. glabrata, Sond. (1850), Miiller has transferred, as a_
