1. Euphorbia pulvinata Marloth, 1. c., p. 315, fig. 1. (Sect. Diacanthium.) 
— Caulis subterraneus, brevissimus, apice ampliatus, ramis brevibus 
simplicibus in pulvino depresso aggregatis, verticaliter 7-costatis, pro- 
funde inter costas sulcatis, pedunculis sterilibus longis spinaeformibus 
pungentibus. Folia linearia decidua. Cyathia in apice ramorum sessilia 
aggregata. Involucrum 2—3 foliolis ovatis ciliatis suffultum, longe- 
campanulatum, lobis brevissimis retusis denticulatis, glandulis rubris 
erectis hemisphaericis margine repandis. — The plant spreads laterally 
by producing numerous branched of equal length, thus forming a slightly 
convex cushion-shaped mass, up to 50 cm in diam. The length of the 
branches is 3—6 cm, their diam. (with ribs) 3—4 cm; the number of 
ribs is mostly 7, sometimes 6 or 8, their edge is slightly crenate, their 
height and width 7—9 mm, the length of the spines 10—15 mm, the 
diam. of the cyathium, which is dark red, 4 mm; leaves 5—10 mm. — 
South Africa: Growing in rocky ground near Queenstown, flowering in 
Nov., Marloth no. 4372, also gathered by Mr. E. Galpin and Mr. E. 
Phillips. 
2. Euphorbia lignosa Marloth, 1. c., p. 316, fig. 2. (Sect. Lyciopsis.) 
— Frutex ramosissimus, compactus, 1—2 pedalis, ramulis crassis rigidis 
acutis subviridibus. Cyathia terminalia solitaria vel terna; involucrum 
campanulatüm lobis brevissimis retusis subdenticulatis, glandulis infundi- 
buliformibus, sub-bilabiatis, labio exteriori 3—4  palmatifido. Capsula 
globosa punctata pilosa, 4 mm diam. — A much-branched very rigid 
shrub with sharp-pointed branches, forming a nearly hemispherical 
compact mass up to 1 m in diam. Leaves, on young shoots only, linear- 
oblong, 10—15 mm. Flowers probably in winter, as only a few old 
flowers could be found in November. The species does not readily fit 
into any of the sections established by Boissier. It is placed here into 
Lyciopsis on account of its habit, but, as pointed out by Bentham in the 
Genera Plantarum, habit does not always conicide with the characters 
taken from the form of the glands. — South Africa: On stony ground 
or rocks in the desert of Great Namaqualand, near Tschaukaib, at 
an alt. of 900 m and a distance of 60 km from the coast of Angra Pe- 
quena. Marloth no. 4637. 
3. Euphorbia namibensis Marloth, |. c., p. 318, fig. 3. (Sect. Medusea.) 
— Caulis crassus globosus vel breve-cylindricus; rami breves succulenti 
podariis elongatis conicis, foliis linearibus deciduis. Involucra sessilia 
campanulata basi bifoliolata, lobis brevissimis obtusis ciliatis, glandulis 
bilabiatis; labio superiori brevi mutico vel subemarginato, inferiori in 
3—4 lacinias subulatas partito; stylis haud divisis. — The stem is 
whitish, club-shaped, nearly globose or somewhat elongate, up to 15 cm 
in diam. and 15—20 cm high. The cylindrical branches are 2—4 cm
