CEASSULACE^. 
Crassula teres, spec. nov. (Sect. Pyramidella.) 
(Plate VIII., fig. 4.) 
Caules e radice perenne plures, ascendentes vel suberecti, foliis dense 
obtecti. Folia carnosa, quadrifariam imbricata, transverse elliptica, 
superne concava, ciliata, margine hyalino amplo. Flores terminales, 
capitati, numerosi, albi, petalis linearibus recurvatis. 
The plant is somewhat similar in shape to G. i:>yramidalis, but with 
leaves more like those of G. columnaris. 
The adult stems are 5-8 cm. long and 15-20 mm. in diam., almost 
cylindrical, the four sides slightly flatter. Leaves basin-shaped, trans- 
versely elliptic, fleshy, with a broad hyaline margin and finely ciliate all 
round. Capitulum 25-30 flowered ; flowers nearly white, sweet scented ; 
sepals linear, with a broad hyaline margin, 3 mm. long. Corolla tubular 
and slightly inflated below, the inflated portion 3 mm. long, the free part 
of the petals linear, channelled for its entire length, not mucronate, much 
recurved, 10 mm. long ; squamae cuneate, 1 mm. long, deep yellow. 
Collected in a sterile state on the Sand Eiver Mountains near Prince 
Albert (quartzite) in 1907 ; flowering in my garden at Capetown in 
May, 1912. Marloth 4146. 
EUPHORBIACE^. 
Euphorbia ferox, spec. nov. (Sect. Anthacantha.) 
(Plate VIII., fig. 1.) 
Planta humilis e basi ramosa, ramulis pulvino hemisphaerico aggregatis ; 
caules ramique cylindrici ; rami juniores 9-10-costati, adulti 10-12-costati, 
obtuse sulcati ; costse spinis acutis rigidis numerosis uniseriatim munitse. 
Dioica. Cyathia feminea in apice ramorum sessilia vel brevissime 
pedunculata, longe campanulata, basi foliolis ovatis 5-8 suffulta ; 
involucri segmenta parva, anguste cuneata, truncata, apice lacerata ; 
glandulae transverse ovales, suberectae, virides. Styli baud connati, 
divergentes, stigmatibus bilobis. 
The plants are much branched from a central subterranean stem, 
forming a compact cushion, 9-20 inches in diam, ; bristling with long 
and stout, nearly straight spines. Stems 30 mm. in diam., 10-12 ribbed, 
the younger branches 9-10 ribbed; ribs 6-8 mm. broad and 4-5 mm. 
high, the crest smooth near the apex, but lower down raised into blunt 
teeth between the spines. Spines uniseriate, stout, sharp-pointed, on 
older shoots 20-30 mm. long, those near the apex straight, the others 
curving slightly upwards, close together, often only 3-4 mm. distant from
