Hab. Most abundant in the interior and northern parti of the Oolon y, often glowing in iwittpj 
ground, ascending to 4000 feet.— (Fl. Jan.) {v. v.) 
Distrib. South-eastern Australia. (Cultivated in England.) 
A very variable plant according to Gunn, inhabiting many situations wet and dry, at limes even growing in 
water six feet deep in Lake St. Clair, as Calycothrix does. A shrub varying from 1-fi feet high.- / 
set, almost imbricating, very rigid, narrow lanceolate, acuminate, pungent, 1 inch long or less. FU>Ker-»pike* 2-4 
inches long. Calyx quite glabrous. Filaments very long, yellow--iv.ii.

The Gum-trees form one of the largest and most important genera of plants 111 Australia, and that w 
contains by far the greater number of forest-trees. They abound in all parts of tin 
fully 130 species being known, of which 50 are confined to South-western Australia, 60 to Boutin 
and 20 are tropical species. It is most remarkable that, with the exception of a Timor and a t 1 
species, none have been found elsewhere but in Australia. 
The species are extremely difficult of discrimination, nor can they be property determined from dried sp 
mens, important characters residing in habit, tie 
racters of the species that I met with growing there, but I am mde 
mation for far better materials than I could collect myself 
puzzled as to the limits of several of the species, and can only offer I 
ones as an attempt. I think I have kept separat
