 have seen are most of thorn very inconifdete, and tliose describetl 

 R. Crown unfortunately mislaid" [at the Museum]. One suspects here a 

 merely cursory searc]i,for the specimen lias long been In its placet among <he 

 species of Trihulns. It is to this that Bentham's error is due, as the plant lie 

 umlcrstands as 7\ Tlysfrix is obviously not that of Brown, 



A few further details about 1\ Ilystrix may now bo given : — 

 Phmta saltern bispithamea indumento dilute fulvo obtecta. Caalis ^vvciws^

After describing T. Hijstruc^ Brown (Z. c.) continues: — 



'' Obs. !• A species nearly related to T. Hy&trix^ found on the west coast 

 of Australia, or ou some of its islands, in the voyage of the * Beagle,' may 

 be tlistinguished by the following character. Tribnlus {occidentaHs) sericeo- 

 lanatus, foliis suboctojngis, coccis undiqne dense armatis : spinis omnibus 

 conico-subulatis longitudine invicem fcquali!>us. Those two species diU'er 

 from all others in the uniform shape of the spines, which equally cover' the 

 whole external surface of the fruit," (PL 11. A. tig. 2,) 



Bontham [Lc.) merges T, occideutalis m T, Ilystrix ^' f rom the sliort 

 diagnosis given," althougli doubt might well have entered his mind at this 

 point, since, while the specimens ho considers to represent T, Iffjslrix liave 

 flowers ^' smaller than in T. cistoides^^'' J^rown expressly says thatfiiat species 

 has ^'flores magni," and the floi'al difference should have led him, irrespective 

 of Brown's reputation, to suspect difference in the fruit. Unfortunately ihc 

 ty2^e of 1\ occideutalis has been mislaid at the Museum, but material there
