The affinity of tins species is with E. ciutioides Forst., from which it can 
be distinguished at once by its lower more widely and dichotomously branched 
habit, by its acute leaves^ and by the seeds which are densely co^'ered with 
large haj’d and white papilla-like excresences naiTowed towards the base, 
and, furthermore, the caruncle is almost hat-shaped, and its lower disciform 
end is separated from the seed by a short and narrow stalk or constriction. 
Euphorbia hravpM/nji/a is a cyanogenetic plant toxic to stock, especially 
hungry travelling stock, and has accounted for the death of thousands of 
-sheep and cattle in tin* Gascoyne and ifurehison districts, especially in the 
vicinity of Jindia Jimlia, the Lyons River, and in places north-west of Cue. 
Euphorbia ciutioides (Forst f.) C, A. Gardn. comb. nov. 
{Croto7h clutiokles Forst f. Prodr., 92 (1786).) 
(Enplhor}>ia htnnensi?i Sprtmg., FI. Hal. Mant. 42 (1807).) 
[E, Vieilardi Baill, Adansonia ii. 212 (1862).) 
(E, eremophila A. Cunn ex Hook, in Mitch. Trop. Austr. 348 (18-18).) 
Its range extends from the Island of Tanna in the New Hebrides to West- 
ern Australia, eml)racing New Zealand and the northern half of Australia. 
E. hodphtlwna is so far only known from W(‘stern Australia, but it appears 
prol)able that its range will be found to extend into Central Australia. 
E. ciutioides does not appear to be toxic to stock.
