CONTRIBUTIONS TO THE QUEENSLAND FLORA, NO. 8.

Several of the above specimens had been distributed previously as 
Trichinium calostachyum F. Muell. but the scale-like teeth between the 
Stamens characteristic of that species are missing in the specimens 
quoted above. The type gathering is not available to me and the descrip- 
tion in the “Flora Australiensis” v. 238 “dorsal hairs not so dense nor 
so long as in most species” I hardly think applies. Our specimens agree, 
however, with material from north-west New South Wales distributed 
by the National Herbarium, Sydney. According to J. M. Black, “Flora 
of South Australia,” 213, the species occurs in New South Wales but has 
not been collected in South Australia since the original gathering was 
made in that State. 
Family Chenopodiaceae. 
Bassia bicornis ( Lindl .) F. Muell. var. horrida n. comb. 
Scleroiaena bicornis Lindl. var. horrida Domin Bibl. Bot. Heft. 89, 
Teil 1, 69 (623) (1921). 
Scleroiaena horrida Domin, l.c. (in obs.). 
This plant is very common in Western Queensland, where along 
with the normal form it is popularly known as Goat Head. It is one 
of the most objectionable burr plants of the interior. Domin has sug- 
gested it might be worthy of specific rank and this was my impression 
for some time, but on close examination I cannot find any substantial 
differences other than the size of the fruiting perianth and the length 
of the spines. In the normal form the fruiting perianth averages 1 cm. 
across and the spines 1 inch long ; in var. horrida the fruiting perianth 
averages 5 mm. across and the spines 5 mm. long.
