rather densely tomentose with rather long spreading soft hairs. Leaves 
almost sessile, ascending-spreading, 17-2? in. long, 7-10 lin. broad, 
somewhat lanceolate or gradually tapering from the cordate or 
subeordate base to the acute apex, tomentose along the midrib 
above and beneath, otherwise glabrous, narrowly thickened at the 
margin, reticulately veined. Umbels lateral at the nodes and terminal, 
sessile, 3-4-flowered ; pedicels 4-1 in. long, tomentose. Sepals more or 
less reflexed, 32-4 lin. long, ? lin. broad, linear-lanceolate, acute, with 
some scattered hairs on the back and sparsely ciliate. Corolla lobed nearly 
to the base, reflexed; lobes 44 lin. long, 2 lin. broad, oblong, subacute, 
inner surface covered with exceedingly minute hair-like papills. Coronal- 
lobes arising at the base of the staminal-column and nearly or quite as 
long as it ; erect or slightly spreading, 24 lin. long, 14-14 lin. broad above 
the middle, thick and fleshy, spathulate-obovoid, somewhat abruptly 
narrowed into the claw at about the middle, forming a slight angle on 
each side, obtuse, very convex on the back, flat on the inner face, with 
an obtusely triangular median keel at about the middle and a short 
transverse keel on each side of it. Staminal-column 2} lin. long and 
a8 much in diam. at the base, broadly conical; anther-appendages 
broadly subcordate-ovate, subacute, inflexed over the depressed apex of 
the style; anther-wings } lin. broad and much projecting at their 
base.—Gomphocarpus sessilis, Decne. in Ann. Sc, Nat. ser. 2, 1x.

_ Described from Decaisne’s type specimen, which consists of a piece of the ter- 
nal part of the plant about 5 in, long, with 4 pairs of leaves. The indumentum 
on the stem, pedicels and midribs, although best described as tomentose is somewhat 
Peculiar and slightly shaggy, the hairs are unequal in length, 4-3 lin. long, soft and 
Jointed, very spreading. The coronal-lobes are inaccurately described by Decaisne ; 
I find them as described above.

1-1} ft. high, pubescent with rather minute curved hairs. Leaves 
Opposite, subsessile, 13-3} in. long, }-1} in. broad, thinly coriaceous, 
oblong to oblong-ovate, abruptly acute obtuse or retuse at the apex, 
apiculate, cordate at the base, narrowly thickened or revolute along the 
Margins, glabrous on both sides, or with a few minute hairs scattered 
along the midrib above and beneath. Umbels lateral at the nodes and 
terminal, sessile, 5—8-flowered ; pedicels 4-8 lin. long, pubescent along 
one side. Sepals 2-3 lin. long, 3—3 lin. broad, lanceolate, acuminate,

lobed nearly to the base; lobes apparently campanulately spreading, 
3-3} lin. long, 13-2 lin. broad, oblong, subacute, ciliolate, covered with 
exceedingly minute hair-like papille on the inner surface. Coronal-lobes 
arising at the base of the staminal-column and about as long as it,
