Pachycar pus. | ASCLEPIADEZ (Brown). 725 
beneath ; flowers in 2-4 clusters of 2—4, lateral at the uppermost 
nodes ; pedicels 4—7 lin. long, scabrous ; sepals 5-6} lin. long, 2-2} 
lin. broad, lanceolate or ovate-lanceolate, acute or acuminate, 
pubescent ; corolla lobed nearly to the base; lobes campanulately 
spreading, concave, with recurved or spreading tips, 7-8 lin, long, 
4—5 lin. broad, ovate or lanceolate-ovate, acute, thinly pubescent on 
the back, glabrous on the inner face, yellow (or in dried flowers 
apparently whitish) spotted on the back with dark violet ; corona- 
lobes 5-6 lin. long, with the basal half claw-like, abruptly dilated 
into ascending-spreading deltoid obtuse auricles at the base and 
there 17-2 lin. broad, bearing 2 erect thin longitudinally folded 
sublinear keels 14-1} lin. high and 3-1 lin. broad at the base 
narrowing upwards to the truncate or emarginate apex, with the 
halves (from the fold) directed outwards contiguous at the top, 
gaping below, and the other halves placed nearly at right-angles 
to them and extending to the tips of the auricles, apparently 
yellowish ; beyond the keels the margins of the claw incurve, 
forming a channel or sometimes almost a tube, and the terminal 
part of the lobe is dilated into an ovate acute concave blade 2}—3 
lin. long, 24 lin. broad, apparently incurved-erect, purple-brown ; 
staminal column about 2 lin, long ; anther-appendages about 1 lin. 
long, broadly ovate, obtuse or subacute, slightly folded longitudinally, 
rather closely incurved over and concealing the style-apex ; anther- 
wings 1? lin. long, straight or slightly convex on their outer margin, 
very prominent at the base. 
Eastern Reaion: Griqualand East; near Kokstad, 7'yson (a specimen dis- 
tributed to the British Museum with P. dealbatus in MacOwan and Bolus Herb. 
Norm. Austr.-Afr, 1315)! Natal ; valley of the Buffalo River, near Charlestown, 
5000-6000 ft., Wood, 4801! hill-side at Rock Fountain, Ixopo Div., Mrs. Clarke ! 
This resembles P. natalensis in appearance, but the corona-lobes and anthers are 
quite different. Mr. Wood states on his label that the flowers are ‘‘ yellow and 
brown,” the latter colour probably refers to the corona.

stem apparently about 10-12 in. high, simple, stout, slightly 
Scaberulous along 2 broad lines; leaves more or less spreading ; 
petiole 2-3 lin. long; blade 14-23 in. long, about 1 in. broad near 
the base, ovate-lanceolate, acute, broadly cuneate or rounded at the 
base, often undulate, slightly scabrous on both sides or glabrous 
above, scabrous on the margins ; umbels subsessile or pedunculate, 
lateral at the nodes, 3-6-flowered ; peduncles 1-5 lin. long ; pedicels 
}-} in. long, scabrous-pubescent ; sepals about } in. long, 2-2} lin.

staminal column by about half their length, spreading out from its
