Stem short, herbaceous. 



Leaves compound (the first few are simple), radical, alternate, 

 stipulate, petiolate, silky at the margin, otherwise glabrous, some- 

 what fleshy, thick, alternately and ascendingly penninerved, deep 

 subglaucous-green ; petioles deeply channelled above, gradually 

 dilated to a wide amplexicaul base, hairy ; stipules almost wholly 

 adnate to the petiole (in young seedling) with small, subulate, brown 

 free tips. 



No.l. Simple, entire, narrowly obovate-elliptic, minutely cuspidate 



No. 2. Simple, oblong-elliptic, minutely cuspidate. 



Lotus Tetragonolobus, L. 



Primary root stout, fleshy, tapering downwards, with a few fleshy 

 lateral rootlets, and comparatively large flesh-coloured tubercles. 



Hypocotyl erect, terete, stout, colourless, glabrous, partly sub- 

 terranean, 2-8-3-2 cm. long. 



Cotyledons broadly oblong, cordate at the base, rounded at the 

 apex, petiolate, fleshy, glabrous, five-nerved but very indistinctly 

 and seen only on the under side, deep opaque green above, paler 

 beneath and shining ; lamina directed slightly to one side, 1'3-1'S 

 cm. long, 1-1-1 cm. wide ; petiole very broad, grooved above, 

 convex beneath, connate at the base, pale green almost colourless, 

 minutely dotted with red, glabrous, articulated with the lamina, 

 5 mm. long, 3 mm. broad. 



Stem herbaceous, annual, erect, dividing into four immediately 

 above and between the cotyledons, pale green, densely hairy, almost 

 villous ; two branches take the lead and are the strongest ; primary 

 internode of the stronger pair of branches 1-1.4 cm. long ; of the 

 weaker pair 4-7 mm. 



Leaves compound, cauline, alternate, stipulate, petiolate, some- 

 what hoary with pale-coloured or whitish hairs on both surfaces, 

 glaucous-green above, paler beneath ; leaflets alternately and ascen- 

 dingly penninerved with the nerves discernible by transmitted light 

 only, articulate with the petiole, the lateral one sessile, the terminal 

 one shortly petiolulate ; stipules foliaceous, obliquely triangular, 

 obtuse, radiately nerved from the base, hairy on both surfaces like 

 the leaves, sessile, not articulated with the petiole, but seated at its 

 base and partly on the stem, semi-amplexicaul. 



No. 1 on the larger branches. Ternate ; terminal leaflet obovate, 

 obtuse, entire or minutely emarginate, petiolulate ; lateral leaflets 

 sessile, obliquely obovate, unequal-sided, with the broadest half on 

 the posterior side of the midrib, minutely cuspidate. 



No. 2. Similar, but the terminal leaflet entire.
