Macbride — Notes on certain Leguminosae uy 
young branchlets and peduncles. It is evident from the descrip- 
tion of Mimosa grandiflora L’Hér. that it cannot be the same as 
Kunth’s plant which has the divisions of the pinnae usually dis- 
tinctly confluent and very oblique at base. I think there is no 
reasonable doubt but that it is rather referable to C. Houstoni 
(L’Hér.) Benth., a species which varies in the number of pinnae 
and the degree to which the leaflets are confluent. C. Houstont, 
frequently distributed as C. anomala, is characterized by dis- 
tinctly apiculate leaflets which are more or less pubescent (very 
rarely glabrous) beneath. The leaflets, too, are uniformly larger 
than those of C. anomala and its variety. Mr. G. Claridge Druce, 
Bot. Exch. Club, iii. v. 415 (1914), treats C. Houstoni under the 
name C. inermis (L.) Druce on the ground that Gleditsia inermis 
L. Sp. PL. ed. 2. 1509 (1763) is the earliest name. Bentham, how- 
ever, Trans. Linn. Soe. xxx. 557 (1875), has shown that G. inermis 
was based on several diverse elements only one of which, — the 
reference to Miller’s figure (Ic. t. 5) — represents C. Houstont. 
Linné’s name, therefore, — if it is not to be rejected on the grounds 
that it “embraces elements altogether incoherent” —is to be 
taken up for Acacia javanica (Lam.) DC. since as to description 
(in large part) and habitat it applies to this plant of which only 
the foliage is known. It would seem, however, that this name, 
based on three widely different plants, viz., the thornless state of 
Gleditsia triacanthos, Acacia javanica and Calliandra Houstoni, is 
& name to be dropped in accord with Art. 51, 4 of the Enterpetienal 
om quoted above.

There is nothing in the description of A. Selloi to indicate that 
Bentham was not justified in referring it to his C. brevipes.
