CONTRIBUTIONS TO THE FLORA OF AUSTRALIA. 193 
In Proc. Roy. Soc. Vict., xx, 1907, p. 84, it was shown 
that P. praecox, Lindl., must be reduced to a variety of 
the above species, and that many of the connecting forms 
could be grouped into a special variety (var. intermedia). 
Another connecting link is afforded by the P. constricta 
of O. H. Sargent (Journ.W. A. Nat. Hist. Soc. No. IV) with 
its numerous related forms. We have no proof of the 
hybrid origin of the very numerous intermediate forms, and 
hence it is at present only possible to make Pterostylis 
reflexa, K.Br., include as well as the type form and the 
variety intermedia, var. praecox (P. praecox, Lindl.) var. 
constricta, Sargent (P. constricta, Sargent) and all the 
forms joining these varieties together. Additional unre- 
corded locality for P. refiexa, var. constricta, Cowcowing,

Ptilotus (Trichinium) Kennedice, F.v.M., inedit. (Amar- 
antacez) = Ptilotus calostachyus,var. Kennedice, F.v.M. 
The sole specimen isa scrap only. On reference to Kew, 
Mr. Farmar considered it to be an undescribed species. It 
has apparently no intrastaminal scales, but this character 
appears to vary somewhat in P. calostachyus and the 
trifling difference in the bracts is hardly sufficient to 
establish a new species, at least until fuller material is 
available. Tandarlo via Wilcannia, Darling River, N.S.W.

Rhagodia crassifolia, R. Br. and R. spinescens, R. Br. 
(Salsolaceze). 
In their extreme forms these are distinguished by the 
former having no spines, and rather long narrow leaves, 
while the latter has shorter and broader more or less deltoid 
or orbicular leaves and is commonly spiny. The fleshiness 
of the leaves is not a reliable character, many specimens 
of R. spinescens having leaves quite as thick and fleshy as 
any of R. crassifolia. In addition many specimens with
