P. carnosum (Ait. Hort. Kew, ii. 421). Caulibus inconspicue griseo- 
puberulis, petiolis foliis subsequantibus, foliis oblongis profunde 
pinnatifidis pinnis late foliaceis rhomboideis extrorsum _ inciso- 
serratis infimis exceptis contiguis, umbellis 5—6-floris, pedicellis 
subuncialibus, calycis segmentis lanceolatis acutis distincte mem- 
branaceo-marginatis, petalis albis superioribus ligulato-spathulatis 
calyce paullulum excedentibus introrsum rubro-venosis, inferioribus 
calyce paullulum brevioribus. — Willd. Sp. Plant. iii. 686; D.C. 
Prodr. 1. 655 ; Harv. Fl. Cap. i. 278. 
A native of the Cape of Good Hope. 
Main branches succulent, half an inch or more thick, greenish 
and finely gray-downy when young, gray and naked when old. 
Flowering branches erect, about a foot high, simple or branched 
again. Petioles nearly equalling the leaves, which in our plant 
under cultivation are two to four inches long by an inch anda 
half to two inches broad, oblong in general outline, deeply 
pinnatifid with rhomboidal divisions toothed principally along 
the outer edge, the lowest pair often remote from the rest, which 
are contiguous, the texture quite herbaceous, both surfaces pale 
green and subglabrous. lowers in umbels of five or six flowers 
each, on erect peduncles four to six inches long. Bracts 
lanceolate-deltoid, recurved, about a line long. Pedicels often an 
inch long below the spur, inconspicuously downy. Calyx-spur 
a line and a half to two lines long, the divisions a quarter of an 
inéh deep, lanceolate with a distinctly-marked white edge. Petals 
white with a slight pinkish tinge, the upper pair rather larger 
than the others, a little exceeding the calyx and veined with red 
in the throat. Fertile stamens five. 
This is not exactly the variety figured by Sweet (Otidea 
carnosa, t. 98), which has more compound leaves and shorter 
pedicels. It comes near to the P. mamillosum of Wendland 
(Hort. t. 70) and our P. sisonifolium (ante, 'Tab. 28), and may 
also be compared with P. lazwm, Sweet, t. 96. All of these are 
certainly included by Harvey under his idea of P. carnoswm 
in ‘ Flora Capensis.’
