CRASSULA, Linn., sect. TILLAEOIDEAE , Schonl. 
Height of plant 5—7 cm. Leaves 2—4 mm. long. Pedicels up 
to 4 mm. long. Petals l - 5 mm. long. 
I am quite satisfied now that my Gr. Simiana cannot be specifically 
separated from Gr. corallina (for some notes on this plant see Schcin- 
land in Journ. Linn. Soc., Bot. XXXI, 1897). This species leads up to 
Gr. deltoiclea, L. and allied species. 
Thunberg’s plant was found “in campis siccis Hantum inter 
Daanis et Rogge veldsberg.” It extends from Little Namaqualand 
and Bushmanland to the Stormberg and southwards to the neigh- 
bourhood of Somerset East. Pearson notes that it grows in sandy 
places.

“ Caulis filiformis basi simplex sursum dichotome ramosus nodis 
distantibus. Folia ovato-lanceolata acuta margine scabrida plana, in 
sicco translucentia venata. Flores tetrameri in cyma terminali laxa, 
pedicellis filiformibus. Calyx profunde 4-partitus lobis lanceolatis 
acutis petalis lanceolatis acutis subaequalis ” (ex Harvey, l.c.). 
“Stem 15 — 24 cm. long, simple for f of its length; internodes 
2'4— 4 - 8 cm. long, leaves - 6 — TO mm. long, '4 — '6 mm. wide, with 
purple veins. Flores 2 — 3 mm. long ” (ex Harvey, l.c.). “ Between 
the Omsamwubo and Omsamba, Caffr., Drege.” 
I have not seen the type of this species, nor have I come across 
a plant that fits the description. Harvey says it resembles Gr. centau- 
roides in miniature, and in spite of its small tetramerous flowers, 
I should judge that it will probably have eventually to be classed near 
it. It seems to be impossible to decide whether this is Thunberg s 
plant. Harvey, who had seen Thunberg’s Herbarium, could not place 
Thunberg’s Gr. prostrata. 
34. Grassula debilis, Thunb. in FI. Cap. ed. Schultes (1823), 280 ; DC. 
Prodr. ill, 388. 
Purgosea debilis, G. Don, Syst. in, 104. 
This species, which was placed byDe Candolle under sect. 1 urgoseae, 
cannot be identified by me. I give Thunberg’s description, with some 
slight verbal alterations.
