says, "Branches clothed with minute pubescence, . . . 

 nerves of leaves conspicuous {pinninerviis) " [in his faithful 

 drawing represented 6- jugate and opposite] . " Flowers ter- 

 nate, pedunculate, drooping ; perianth turbinate, 5-6-toothed, 

 downy as well as peduncle. Filaments shghtly protruded ; 

 anthers oblong" (" Icones Plantarum," vol. vii., tab. 630). 



II. I have received only two small specimens of this plant, 

 both male, each possessing 12-14 leaves and 12-20 flowering 

 perianths, apparently obtained as if casually gathered in pass- 

 ing ; yet their difference is so great from F. fusca, vera, as 

 described and ably drawn by Hooker, that I have considered 

 it right to bring this plant to notice, even should it hereafter 

 prove to be a variety only of F. fusca. A peculiarity in the 

 leaves of these two specimens is that they are nearly all 

 repeatedly bored through by some insects, twenty holes and 

 upwards in some leaves. 



Class II. MONOCOTYLEDONS. 



Order I. Obchidb^. 



Genus 12. Pterostylis, Brown.

 l-|-in. long, lin. broad, tips very obtuse-rounded, many-nerved 

 lo'ngitudinally, with veins largely anastomosing between 

 nerves. Scape 1 in. long, stout, erect ; flower solitary. Peri- 

 anth IJin. diameter, sepals and petals nearly equal in length, 

 narrow, sub 8 lines long, membranous and veined, not long- 

 tailed ; tongue narrow, thickish, dark-red, tip subacute, ex- 

 serted ; appendage large, membranous, venied, erect, curved, 

 tip acute ; column wings upper and lower corners largely 

 produced, tips narrow-acute. Capsule very stout, obovoid,

Hah. Ruahine Mountain-range, east side, near secondary 

 summits; 1898: Mr. A. Ols&n. 



Obs. Only a single specimen received, and that with 

 withered (though perfect) perianth, so could not afford to 

 break it up for closer examination. A species very distinct 

 from all other New Zealand ones known to me.
