each other. Plants dioecious. The female cyathia on short pedicels, 
1 mm. long, bracts 6-8, the lowest very small, the three upper broadly 
oval, blunt and lacerated at the apex, ciliate. Involucre tubular cam- 
panulate, 3 mm. long, at the mouth 2 mm. in diam. ; segments not 
touching each other, ovate-cuneate, truncate, finely lacerate at the apex ; 
glands suberect, transversely oblong, green, rugose, the margin wavy, but 
entire. Ovary ovate, acute, the styles joined for 1 mm., the branches 
2 mm., spreading, the stigmas red, bilobed. 
In its general habit this plant somewhat resembles E, j;?tZz;mato, 
Marl. (Trans. Roy. Soc. S.A., vol. i., 315), but the branches are longer, the 
spines more numerous and much stouter, and the flowers quite different. 
Gathered at Klipplaat (Eastern Karoo), and cultivated in my garden 
at Capetown for many years, flowering the first time August, 1912.

Euphorbia piliflora, spec. nov. (Sect. Medusea.) 
(Plate VIII., fig. 3.) 
Planta humilis, caule clavato, apicem versus ramis nonnuUis erectis, 
crassis, brevibus, foliis linearibus ; pedunculis elongatis filiformibus. 
Cyathia cylindracea, segmentis obovato-obtusis, ciliatis ; glandulae hori- 
zontales, oblongae, centro depressae, virides, dentibus 4-5 linearibus, albis, 
apice recurvatis ; ovarium triangulare, stylo longo, stigmatibus brevibus,

The plant resembles in its general habit E. midticeps from the karoo 
and E. namibensis from Great Namaqualand, but differs conspicuously 
by its long filiform pedicels. Stem 20-30 cm. high, 8-10 cm. in diam., 
the branches 5-8 cm. long and 8-10 mm. in diam., the podaria conically 
elongate, their apex curving slightly downwards ; leaves linear deciduous, 
20-30 mm. long. Peduncles 6-9 cm. long, filiform, bearing 2 or 3 
distant bracts ; cyathium 12-14 mm. long and half as wide ; glands 
1-| mm. long and 2 mm. broad, the teeth 2 mm. long. Ovary shortly 
stipitate, styles 5 mm. long, for f of their length connate. 
The latex of this species is employed by the colonists for removing 
warts from man or beast. Marloth, No. 5119, sterile, at Chamis in Great 
Namaqualand, October, 1910. Also sent from Concordia in Little
