 Wilt s, with a curious northern outlier on the Bamugtoi: Tops, N.SAV. (he- 

 tu-oeii Gloucester and Scone, at 5,100 ft. allitude). m leaves vary from a 

 minimum of 10 x 2..i mm, on the Baw Bawa. Vic., to a maximum (at leHM in 

 all the material so far examined by me) of 100 x 25 mm oji Mi. liJIcry, Vit. 

 Corresponding differences occur in number of *tamen* oer flower — 4-6 only 

 On the Baw Bmw* to 25 on Mt Ellery. An between the*e extremes, I have 

 observed tvCfy possible gradation on various Victorian mountain peako. 



Smith specific* solitary carpel* for his type of IX vickwiann; bur within 

 the ivnc area [Briv Buws) it is not unusual to find frmtinfr ipecuncos with

 serve to distinguish any form Hi f* vcrttphifa from D (ntuc i ithin — sole retire*

J. caves of /}. hvirrolottt .are usually inwtr at the tip, of thiu texture, atid 

 they remain o^hc-tirecuhh in the dried staff; those of FJ. xcroph\lo, by con- 

 trail, are always ohUisc, of thick ritftd texture {the veins usually obscured) 

 and they become charjvlefi*i>e;01y rub^swut — bftofl with a ^Jancou* appear- 

 ance as well— when dry. The brancblerv of ihe latter speciec. are consistently

PariffiUlliei Wa3 justified in cstabhslhr.^ the ^pecie^ JD. TtlPGpbyls, but he 

 erred unaccountably in hi; deliinitafion o! 'his and of /> hun-iUafa (which he

 dthned palisade cells in its foliage and that tt&tppftUtfn fecks them should be 

 re\eTfied! The «p«Q|»CN (in Paris — "Victorian Alps". rVjf, C. Waltei ) il'at 

 he pronounced as typical O. aroiratica is actually identical with lyjx; /?. .r*'ro-
