XXI. LYSILOMA. 
Calyx campanulatus, 5-dentatus. Corolla subinfundibuli- 
formi-campanulata, 5-fida, laciniis membranaceis. Stamina 
indefinita (sæpius infra 30) corolla vix triplo longiora, basi 
in tubum a corolla liberum coalita. Ovarium sessile v. brevi- 
ter stipitatum. Legumen (in L. stipulari et L. rostrata) 
lineare, rectum v. vix falcatum, plano-compressum margine 
incrassato integro a valvulis submembranaceis maturitate 
soluto.—Frutices v. arbores in America calidiore crescentes, 
habitu Acaciis similes, inermes.  Stipule sepius jfoliacec v. 
membranaceee.  Felia bipinnata, pinnis foliisque plurijugis. 
Glandula petiolaris elevata, jugales paucae. Pedunculi axil- 
lares, nunc solitarii v. fasciculati, nunc in ramos racemose 
olizocephalos aphyllos abeuntes. Flores ssepius numerosi, 
parvi, sessiles, staminibus rarius semi-pollice longioribus. 
The species I have collected under this generic name are 
evidently closely allied to each other, although there can be 
no certainty of their being truly congeners until the fruit of 
more species shall be known. The generic character lies in 
the combination of the pod of a Mimosa with the monadel- 
phous stamens of the Ingoid genera. The calyx and corolla 
are those of several Acacias, the stamens longer than in most 
species of that genus, and apparently not yellow, but shorter 
and fewer than is usual in Calliandra. Some species very 
much resemble Leucena in habit, and the form of the pod 
of L. Schiedeana is the same, though the vara is very 
different.
