connects the marginal notches and keels; appendage arising near 
the top of the lobe, 3—1 lin. long, subulate, closely incumbent on the 
top of or loosely incurved over the staminal column and style-apex, 
often crossing at the tips, not erect, usually curved; anther appen- 
dages broadly ovate, obtuse or subacute, inflexed on the top of the 
truncate or umbonate style-apex; follicles 3-31 in. long, 2} lin. 
thick at the lower part, narrowly fusiform, tapering into a long 
slender beak, puberulous. Schlechter in Journ. Bot. 1896, 421.

Var. 8, longirostre (N. E. Br.) ; appendage of the corona-lobes erect or 
connivent at the base and then erect, or S-curved or somewhat tortuous at the 
tips, much exceeding the staminal column. 8S. longirostre, Schlechter in Engl.

The specimens above quoted have been described by Dr. Schlechter as 3 distinct 
species, differing in the pubescence on the inner face of the corona-lobes. 8. 
glabrescens is described as having them puberulous all over, and is so repre- 
sented in Dr. Schlechter’s own drawings of his analyses of the flower, S. tenuissimun 
as puberulous on the lower half only, and S. longirostre as glabrous. ‘This 
pubescence is always very minute, and is certainly very variable, as in different 
specimens of the same gathering made by Dr. Schlechter and others I find 2 or all 
3 forms of it to exist. With the exception that the appendages of the corona- 
lobes or their tips are erect, I can find no specific distinction whatever between 
S. longirostve and the others, and the corona-lobes are not ovate-lanceolate nor 
lanceolate as originally described. 
65. S. lamellatum (Schlechter in Verhandl. Bot. Ver. Brandenb. 
xxxv. 48); stem 73-16 in. high, simple or slightly branched, minutely 
pubescent, with internodes 3-2 in. long; leaves erect or ascending, 
subsessile, 3-11 in. long, 11 lin. broad, linear, acute, with revolute 
margins, nearly glabrous or very minutely scabrous; umbels 3-5, sessile 
at the nodes, 2—5-flowered ; pedicels 3-1} lin. long, puberulous ; sepals 
2 lin. long, 3 lin. broad, ovate, acute ; corolla-lobes 1-1} lin. long, 3 lin. 
broad, oblong-ovate, subacute, campanulately spreading or suberect, 
sometimes apparently with ineurved tips, glabrous or with very few 
hairs on the back, the inner face as seen under a strong lens is 
covered at the basal or apical half with exceedingly minute papilla- 
like hairs, but appears glabrous under a weak lens, apparently 
greenish, purple-tinted on the back, ‘ brownish” (Rand) ; corona- 
lobes erect, overtopping the staminal column, about 1 lin. long, 
3-} lin. broad, closely contiguous below, with slightly recurved 
margins, oblong or elliptic-oblong, usually narrowed into an acute, 
obtuse or minutely bifid point, but sometimes abruptly contracted 
into the point or 3-toothed at the top, the lateral teeth minute, 
obtuse, the middle one not move than + lin. long, deltoid or narrow, 
with 2 thin wing-like keels on the inner face, slightly converging
