196 THE NORTH-AUSTRALIAN EXPEDITION. 



occurrence of half-a-dozen species here. Colour of petals is no cha- 

 racter here of these plants whatsoever. 



Nelumbiece. The notes from fresh specimens will, I think, prove the 

 identity of ours with the Pythagorean plant. 



Capparidece. Of Capparis four kinds were noticed, besides those of 

 Sir Thomas Mitchell's discoveries, one forming a noble tree at More- 

 ton Bay. C. lasiantha (the epidendric Capparis of Leichhardt), and 

 0. umbonata extend as far as the Victoria River. 



Rutacece. Two species of Boronia in North-western Australia are 

 remarkable for having much longer sepals than petals ; one with, pin- 

 nate grey leaves resembles Artemisia from the distance, which suggests 

 the appellation B. artemisioides. Three other species were noticed, 

 including B. bipinnata, Ldl. Of Zieria a new kind, with extremely 

 minute flowers, and the habit almost of a Xanthosis occurs on the 

 Glasshouse Mountains; and I discovered also a singularly granulated 

 narrow-leaved species from Sir Thomas Mitchell's collection, not ap- 

 pended to his work. 



Cedrelece. In the Brigalow Scrubs of Eastern Australia a new 

 genus of this Order forms a constant companion of EremopJrila Mit- 

 chelli. The capsule, although not seen in perfect maturity, seems to 

 remain coriaceous ; the placental laminas are two-seeded on each side, 

 and the seeds of all around winged, thus tending to disrupt the limits 

 between Flindersia and Oxleya ; and I should, notwithstanding the 

 want of woody structure of the capsule, have united the three genera, 

 were the flowers of Oxleya known, and did not this new genus, now 

 celebrating the fame of a third Australian explorer, Count Strzelecky, 

 distinguish itself habitually by opposite small leaves and a foliaceous 

 rachis of the leaflets. 



Aurantiacece, a very small Order in Australia, becomes augmented by 

 a well-marked Glycosmu from the Burdikin. 



Hippocratete seemed to be unknown from this part of the globe. A 

 species of Hippocratea, allied to H. obtusifolia, with bearded flowers, 

 occurs on the banks of the Brisbane. 



In Poly galea a new species of Comesperma with spreading leaves (C. 

 patentifolimti) was noticed in Eastern Australia, besides C. sylvestre, 

 Ldl., and u. limarifolium, A. Cunn. Polygala occurs in four species in 

 the Isorth. Salomonia, noticed by E. Br., was not observed during 

 Mr. Gregory's expedition. 



Erylhroxylea have a solitary but very common representative in
