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 coincide with the characters taken from the form 
of the glands. 
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 Pequena. Marloth No. 4637. (See Fig. 2.) 
E, namihensis spec. nov. (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 baud 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. long and 1 cm. in diam.; the leaves, which appear only for a 
short time after rain, are 10-15 mm. long ; diam. of cyathium, 8-10 mm. 
Growing in the stony plains of the desert " Namib," near Tschaukaib, 
at an altitude of 800 m. and a distance of 50 km. from the coast of Angra 
Pequena. Marloth No. 4635. (See Fig. 3.) 
This is the plant figured in Schultze" as Marlothii Pax, and although 
the name is given on the authority of Prof. Pax, it is obviously an error. 
Euphorbia Marlothii belongs to another section, being very different in 
appearance and systematic characters. A fairly good figure of the true 
E. Marlothii is given by Berger in " Sukkulente Euphorbien," p. 117. 
E. cr assises spec. nov. (Sect. Dactylanthes). 
Caulis brevis globoso-cylindricus, ramis crassis numerosis brevibus 
cylindricis. Cyathia in apicibus ramorum stipitata, basin 3-5 foliolis 
spathulatis ciliatis suffulta. Involucrum campanulatum lobis ovatis 
lacerato-ciliatis, glandulis patentibus, concavo-bilabiatis, labio superiori 
brevi, emarginato, labio inferiori breviter 3-4 dentato. Pedunculi deflorati 
persistentes inermes. Styli inferne coaliti apice sub-bilobi. 
The stem is 10-15 cm. thick and high, flattened at the apex, and 
bearing numerous short fleshy branches, the lower ones gradually shrivel- 
ling up and exposing the bare stem. Sometimes the stem remains quite 
short and buried in the ground, the branches forming a rosette 15-20 cm. 
in diam. Length of branches 4-6 cm., their diam. 10-15 mm. ; length of 
persistent peduncles (floriferous branchlets) 15-20 mm., they are woody 
but not sharp pointed. Diam. of cyathium 4 mm., without the teeth of 
the glands, fig. 4.
