Mimosa Herzogii, nom. nov. M. eurycarpa Herzog in Fedde, 
Rep. Spec. vii. 53 (1909), not M. eurycarpa Robinson, sh: 
Acad. xxxiii. 322 (1898). a 
The name chosen by Herzog for this unique Mimosa of Bolivia 
must be changed because it has already been used for a vali 
oe species. 
ti sosiiggig om (Michx.) MacM., var. glandul 
(Micke a comb. nov. Mimosa glandulosa Michx. Fl. Bor. Am. 
pp ee “painatonia rack yl DC., var. glandulosa (Mich. he 
a ae differs from the typical form of the species 
which it merges, cf. Torrey & Gray, 1. ¢., in the presence 
gland at the base of all the pinnae, rather than at the base of t 
lowest pair only. 
Desmanthus pumilus (Schlecht.), comb. nov. Mimosa p 
Schlecht. ppt ty xii. 557 (1838). D. incurvus Benth. in | 
Lond. Journ. v. 84 (1846). 
Bentham remarked, 1. ¢., that Schlechtendal’s plant « from 
description would appear to differ “only from D. incurvus in 
breadth of the pod, which is stated to be 3 lines instead of 2 
D. incurvus.” And in his monograph, Trans. Linn, Soc. xxx. 
(1875), he wrote “ Mimosa pumila, . . . is probably, from 
cription, the same species, or one closely allied to it.” I think th 
there is no reasonable doubt as to the identity of these plants. - 
slight discrepancy which Bentham noted in the description of 
pod is of no moment for fully mature pods may attain a 
6 mm. as is illustrated by Pringle’s number 2852 from C0 
It may be noted furthermore that M. pumila was based on a8 
men collected by Ehrenberg at Regla, Hidalgo, which is | 
within the known range of Bentham’s plant. 
Desmanthus hexapetalus (Micheli), comb. nov. 
hexapetala Micheli, Contrib. Fl. Parag. i. 50, pl. 17 (8 
Michelii Hassl. Bull. Herb. Boiss. ser. 1. 3, a 3 1907). 3 
Hassler, |. ¢., has shown that this odd plant is a species sae 
manthus but i rejected Micheli’s specific name 1 
ground that it is rarely applicable. Nevertheless sin es 
is not already used for a valid species of 
_ its aspect when growing must be even more extrao! 
appears from herbarium material.
