EUPHOKBIACE^. 
Euphorbia basutica, n. spec. (Sect. Medusea.) 
Planta humilis, paullo ramosa, non rosulata, podariis rhomboideis, 
obtuse-pyramidalibus. Folia brevissima, lineari-ovalia, concava, decidua. 
Cyathia in apicibus ramorum sessilia, foliolis 3-4 ovato-cuneatis, ciliatis 
suffulta. Involucrum campanulatum lobis latissimis, brevissimis, truncatis, 
denticulatis, viridibus; glandulis sub-stipitatis, transverse-ovalibus, con- 
cavis, punctatis, sub-viridibus, in 4-5 lacinias breves partitis ; styli breves, 
involucro baud superantes, stigmatibus crassis, ovalibus. 
This plant agrees exactly with the figure on plate 150 of De Candolle's 
Plantes Grasses, but is certainly not a form of E. caput meduscB — a plant 
occurring frequently in the neighbourhood of Capetown. Berger in 
" Sukkulente Euphorbien," p. 113, identifies De Candolle's figure with 
E. parvimamma, Boissier (ex Prodromus, xv., 2, p. 86), but his own figure 
of the supposed E. ijarvimar}ima shows the segments of the involucre to 
be triangularly pomted and well fimbriated, while DCs figure in PI. Gr. 
and our plant possess very broad, retuse and finely denticulate segments. 
(Fig. 6 ; magnified 2x.) 
Berger' s plant may be E. parvimamfiia, Boiss., which was named from 
sterile specimens only, or not ; that does not concern us here, but it is 
certainly different from the figure in Plantes Grasses. As the latter agrees 
so well with our plant, it became necessary to name the latter. 
Syn. : E. caput medusm, L., var. nmior, DC. in Plantes Grasses, tab. 150. 
The plant (2 specimens) was sent by Mrs. A. Dieterlen, from Leribe, 
in Basutoland, and flowered in Mr. E. P. Phillips' cultures at the Govern- 
ment Herbarium, Capetown, in February, 1909.
