(See Fig. 1.) 
E. gummifera Boissier (amended description). 
Eruticosa, ramosa, tota minute albo-tuberculata, ramis rigidis erectis, 
ramulorum lateralium brevissimorum decurrentia subangulatis. Folia? 
Cyathia sessilia, glomerata, foliolo ovato-acuminato tomentoso suffulta; 
involucrum campanulatum hirsutum, lobis ovatis acutis integris, extus 
hirsutis, glandulis patentibus, transverse ovalibus. 
A rounded shrub, similar in shape to E. mauritanica as growing in the 
karroo, but with ribbed, woody branches and a hard, whitish, finely tuber- 
culated epidermis, which evidently forms an excellent protection against the 
drifting sand and grit of the desert plains and hills on which the plant 
thrives in spite of the sandstorms. The cyathia are crowded together on 
short lateral spurs of the branches, the bracts and -involucres being 
thickly hirsute or tomentose. The shrubs are nearly egg-shaped or 
somewhat stouter at their base, 1-2 m. high ; the final branches 
6-8 mm. thick ; the cyathia 3 mm, in diam. 
On sandy plains and slopes of the desert Namib near Tschaukaib at an 
alt. of 800 m. and a distance from the coast of Angra Pequena of 60 km. 
Marloth No. 4636. 
This is the first socially growing plant, which one meets in coming 
from the coast. 
Boissier states (DC. prodr. vol. xv., 2. p. 97) that the plant resembles 
E. cervicornis, but this opinion is based on fragmentary herbarium 
specimens, as the two species are very different in habit. E. cervicornis 
is a much smaller plant with stout succulent branches and large leaves. 
It is eagerly eaten by goats and sheep, while E. giimmifera is not only 
too woody to serve as food for the animals, but possesses a nauseous 
and irritating smell. 
E. lignosa spec. nov. (Sect. Lyciopsis). 
Frutex ramosissimus, compactus, 1-2 pedalis, ramulis crassis rigidis 
acutis subviridibus. Cyathia terminalia solitaria vel terna ; involucrum 
campanulatum 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
