which as it happens Krauss does not appear to have collected at all ; 
both, however, are A. languida, E. Mey. Owing to his doubt 
as to this fact, Hochstetter thought it desirable to use for n. 367 
a new name, A. petiolaris; as this name is accompanied by a 
description, whereas the older name, A. languida, had none, 
A. petiolaris, Hochst., is the name which is now employed to 
distinguish this species. 
Under his field number 377, Krauss appears to have collected 
three nearly related but fairly easily distinguishable forms. One 
of these Meisner identified—we believe rightly so, though so great 
an authority as Miiller was of a contrary opinion—with A. pedun- 
cularis, &. Mey. Of the other two, Bucbinger regarded one as a 
_ distinct species, A. crassa ; Meisner described the other as a third 
distinct species, A. punctata. Krauss, however, has remarked in a 
footnote upon the difficulty which he experienced in separating 
A. crassa, Buching., from A. peduncularis. With the view of 
Krauss we entirely agree, and we concur with Miiller in his treat- 
ment of the plant as a variety, var. crassa, of A. peduncularis. But 
as regards A. punctata, Meisn., which is only a form of the species 
already recognised by Meyer under the name 4d. longifolia, we 
concur with Krauss in treating it as distinct, and feel unable to 
follow Miiller in dealing with it as only a variety of A. peduncularis. 
A, glabrata. The account equally omits one of the species, 
A. brachiata, enumerated by Drége ; of the other three it retains only 
the name given by Meyer to A. peduncularis ; the name of A. langu- 
ida, EK. Mey.,is altered to A. petiolaris, Hochst., that of A. longifolia, 
EK. Mey., is replaced by dA. punctata, Meisn. The omission of 
A, brachiata, K.. Mey., is compensated for by the communication of 
the very distinct A. glandulifolia, Buching. 
Up to this point (1845) the South African species of Acalypha 
were known to be 4. glabrata, Thunb. ; A. capensis ; A. petio- 
laris, Hochst. (= A. languida, E. Mey.); A. brachiata, EK. Mey.; 
A. peduncularis, E. Mey.; A. punctata, Meisn. (= A. longi- 
folia, #. Mey.) and finally A. glandulifolia, Buching. 
In Linnaea, vol. xx. (1847), p. 213 there is a list of specimens of 
Acalypha collected by Zeyher in South Africa. The first of these, 
Zeyher 3838, is named A. peduncularis, E. Mey., and the specimens 
show that this identification is correct. The second, Zeyher 3839, 
which is unnamed, became at a later date the type of a new species 
described by Baillon. The third, Zeyher 1518, also unnamed, 
became subsequently, in part, the basis of a new species described 
by Sonder. The next number in the list, Zeyher 1517, is 
applied to the specimens of three gatherings and is treated as in- 
cluding two species. One of these, represented by Zeyher 1517a, 
{s identified with A. glabrata, Thunb., the other, represented by 
Zeyher 1517b and 1517c is provisionally identified with A. betulina,
