Macbride — Notes on certain Leguminosae 13 
which it has been referred varietally. The species may be con- 
trasted as follows.

dull above, bs gt or early becoming glabrate

Mimosa re (Gillies), aoa nov. Prosopis globosa Gillies 
in Hook. Bot. Mise. iii. 205 (1833). M. Gilliesii Benth. in Hook. 
Journ. Bot. iv. 413 (1842) 
Since the specifie name globosa has not as yet been used in this 
genus, Gillies’ name, though not particularly apt, must be taken 
up for this peculiar Patagonian species. 
Mimosa incana (Spreng.) Benth., var. robusta, var. ner = 
ramis multo validioribus; foliolis circa 15 mm. longis circa 
latis utrinque pubescentibus. — — Paracuay: Upper Parand, "Fie. 
brig, 5629 (rypE, Gray Herb.). 
The much stouter branches and larger leaflets distinguish this 
variety. The leaflets of the typical form are rarely 8 mm. long 
and perely glabrous above. 
imosa: macrostachya (Benth.), comb. nov. Schranckia ma- 
crostachya Benth. in Hook. Journ. Bot. iv. 414 (1842). M. muille- 
foliata Scheele, Linnaea, xvii. 337 (1843). 
IMOSA MACROsTACHYA (Benth.) Macbr., var. glaberrima 
(Chod. & Hassl.), comb. nov. M. millefoliata poner var. gla- ~ 
berrima Chod. & Hassl. Bull. Herb. Boiss. ser. 2, iv. 554 (190 
Since the specific name macrostachya is not “ Semdy borne by 
a valid species ” of Mimosa (M. macrostachya Poir. is an Acacia), 
it is available for this plant and must replace the later published 
name of Scheele. 
Mimosa PARAGUARIAE Micheli, var. induta act) comb. nov. 
M. paraguariae Micheli, var. genuina Hassl., forma induta Hassl. 
in Fedde, Rep. Spec. ix. 7 (1910). 
This is a good variety differing from the typical form of the 
Species not only in the presence of the eglandular indument among 
the gland-tipped trichomes but also in the more rigid character of 
the latter. Fiebrig’s number 6124 from the upper Parand is to be 
referred here.
