and their shape is not then in the least suggestive of the 

 mature form. The fruits seen range from 1'6 cm. to 2*4 cm. 

 in length, the diameter being from about 1*1 to 1*2 cm., 

 and the width across the usually thin rim 6 to 7 mm., the 

 capsule sunk. Some old buds which had perished and 

 remained on the tree were about 7 mm. in diameter. 



This is the tree referred to by Leichhardt as Bloodwood 

 near the junction of the Lynd and Mitchell Rivers. He 

 writes: — "The bergue was covered with fine bloodwood 

 trees," (p. 292), and "the bloodwood, the apple-gum, the 

 box, and the flooded-gum, grew along the bergue of the 

 river," (p. 296). He also mentions that the bloodwood 

 was in blossom in June (p. 297). He refers to the tree 

 again (p. 370), when on the Nicholson, and on three sub- 

 sequent occasions, (p. 394, 473, and 529) the last being when 

 near Port Essington. 



This species was in flower at several places, including 

 Frewhurst, the lower Flinders, and near Oloncurry, in 

 August 1913. 



Trees which in habit appear to belong to the same species 

 were flowering in August at Prairie, east of Hughenden (No. 

 3958), but the fruits are larger, being as much as 2*7 cm. 

 long with a diameter up to 2 cm. and the rim is thick, the 

 orifice measuring from about 1 to 1*5 cm. across, the 

 capsule sunk. The flowering period for jEJ. corymbosa is 

 February and March. 



Petalostigma quadriloculare is known in North Queens- 

 land as Quinine, from the exceedingly bitter taste of the 

 numerous small yellow fruits, and it has a very wide dis- 

 tribution. It grows into small trees from fifteen to thirty 

 feet high. Leichhardt refers to this tree throughout his 

 expedition and calls it the "Severn Tree," after the Severn 

 River in northern New South Wales where he first saw it. 

 When near the Norman River he wrote: — "The emu here
