long, l'5-3 mm. broad, the terminal leaflets slightly exceeding the lateral 
ones. Flowers solitary or in pairs, invariably opposite the leaves, shortly 
pedicellate, yellow; bracteoles two, opposite, subulate. Calyx equally 
divided half-way, about 10 mm. long, densely fulvously pilose ; carina 
scarcely exceeding the calyx in length, and slightly appressedly pubescent 
in front.

As a result of a wide diffusion this species is most variable and 
difficult of limitation, but an examination of a series of specimens offer no 
justification for any separation, except where proposed. Var. ma;]or ap- 
proximates very closely to L. calycina, v. acuta, but the tufted, erect habit 
of the annual shoots of the former is very characteristic. All the forms 
agree in having the calyx nearly as long as the carina, while the seeds 
are in all cases a brick-red ; the indumentum is variable.

foliolis floribusque minoribus et carina calycem superante, distinguitur. 
Sujfruticosus prostratus, pumilus, sordidus, parce ramosus, sericeo- 
pilosus; caules ad 5 cm. longi, foliosi. Folia trifoliolata ; petioli ad 2 mm. 
longi; foliola elliptica vel obovata, rotundata aut acutata, basin versus 
attenuata, ad 3 mm. longa, 1*5-2 mm. lata, lateralia aequilonga aut breviora, 
supra mox glabra; subtus sericeo-pilosa, vix coriacea ; stipula una, parvula. 
Flores oppositifolii, solitarii, pauci, breviter pedicellati, probabiliter flavidi. 
Calyx 5 mm. longus, extra sericeus, lobis acutis tubo aequalibus. Vexillum 
unguiculatum, spatulatum, 6-7 mm. altum, acutatum, limbo dorso sericeo ; 
alae breviter unguiculatae, fere glabrae, limbis oblongis rotundatis basi 
truncatis aut obtuse sagittatis ; carina alls similis sed lamina naviculari 
sagittatiore ad margines inferiores ciliolata. Ovarium hirsutulum ; stylus 
prorso arcuatus, stigmate subcapitato. Lipozygis calycina, var. h. E.

Bentham, in describing F. calycina, alludes to this species, which is 
represented at Kew by a small specimen, and opines that it is probably 
distinct. 
The following species, owing to their straight styles and correlated 
straight carinae, or their rostrate carinae, subequally 5-fid calyces and
