778 ASCLEPIADEZ (Brown). | Fockea. 
cate or subcordate at the base, remarkably undulate-sinuate along 
the revolute margins, minutely puberulous above, glabrous except 
on the midrib beneath ; cymes umbel-like, sessile at the nodes, 3—6- 
flowered, minutely adpressed-whitish-puberulous on all parts to the 
outside of the corolla; pedicels }—1 lin. long; sepals 1 lin. long, 
lanceolate, acute; corolla-tube 1 lin. long; lobes erect, 2-24 lin. 
long, ? lin. broad, linear-lanceolate or oblong-linear, acute or obtuse, 
glabrous on the inner face, green ; corona white, with a tube 1} lin. 
long, divided at the top into 5 trifid lobes alternating with 3 teeth 
or with 5 smaller trifid lobes, the middle tooth of the 5 principal 
lobes 14-14 lin. long, filiform, tortuous, all the other teeth }—3 lin. 
long; within the tube the 5 longest teeth are decurrent as stout 
keels bearing above the middle of the tube an erect filiform process 
arising to the level of the shorter teeth, and the teeth on each side 
are decurrent as narrow wings ; anther-appendages nearly equalling 
the corona-tube. Brachystelma sinwatum, E. Meyer, Comm. 196 ;

The type specimen of Brachystelma sinuatum in E. Meyer’s Herbarium, although 
flowerless, is identical with F. undulata, and is labelled as having been collected 
‘*between Kat and Zwart River” in Stockenstrom or Queenstown Div., whilst 
E. Meyer, and also Droge, state that it was collected on hills near Dweka (Dwyka 
River) in Prince Albert Div., and near Brak Vallei in Richmond Div. 
2. F. tugelensis (N. E. Br.) ; in habit, stems, inflorescence and 
pubescence not distinguishable from F. angustifolia, but differing as 
follows :—leaves 1-2 in. long, 2—4 lin. broad at the base, narrowing 
upwards, linear-lanceolate, acute or subobtuse, rounded at the base ; 
sepals about 1 lin. long, narrowly lanceolate, acute ; corolla-tube 
% lin. long; lobes } in. long, 3 lin. broad, linear, with recurved 
margins, twisted, puberulous on the back and with a microscopic 
puberulence on the inner surface, apparently greenish ; corona 
about 24 times as long as the corolla-tube, white, about 1} lin. long, 
tubular for rather more than half its length, usually with 20 or 
sometimes 15 teeth at the top, 5 of which are about 3 times as long 
as the others, filiform, decurrent as stout keels within the tube, and 
bearing at about the middle of the tube 5 erect linear obtuse teeth or 
processes, which rise to the level of the short teeth, 10 of which are 
decurrent as narrow wings or keels within the tube; anther- 
appendages reaching to about ? of the way up the corona-tube.

_ stock a large tuber ; stems several, clustered, usually simple, erect, 
tortuous or sometimes twining, 3-1} ft. long, puberulous with 
- minute curved hairs ; leaves subsessile or very shortly petiolate, 3—
