and solitary heads. I have named this distinct and curious species in com- 

 pliment to Mr. T. H. Potts, of Governor Bay, who has paid much attention 

 to the cultivation of New Zealand plants. 



Trichotnanes Armstrongii, Baker. 

 (ffymenophyllum Armstrongii, Hook, f.) 



A very small species, forming dense dark green coloured masses beneath 

 water-falls ; rhizome creeping, very slender ; fronds about ^ inch long, usually 

 pinnate, but frequently flabellate ; pinnules few, 2—4 lines wide, with no veins 

 but the midrib, and a peculiar purple ciliated margin, which distinguishes the 

 species from any other New Zealand form ; sori 1-2 or 4 to a frond at the 

 tips of the pinnules, obconic and ciliated. 



Hab. — Waterfalls near the sources of the Waimakiriri, altitude 3,800 feet, 

 Dr. Haast and J. B. Armstrong, 1867. 



Veronica anomala, Armstrong, n. s. 



A slender, erect, quite glabrous shrub, 2-3 feet high, with long weak pur- 

 plish branches. Leaves patent, shortly petioled, glabrous, |^— 1 inch long, 

 ^ inch broad, coriaceous, linear-oblong, concave, entire, polished on the upper 

 surface ; midrib obscure. Flowers crowded together at the points of the 

 branches ; sessile in the axils of the uppermost leaves ; sepals ^ inch long, 

 linear-oblong, acute ; corolla white, tube ^ inch long ; limb ^-^ inch broad ; 

 lobes 3 nearly equal, or 2 unequal, with the longer one forked at the tip ; 

 capsule not seen. Flowers in winter. 



A curious plant, difiering from all other Veronicas in the number of coi-olla 

 lobes. In foliage it much resembles V. vernicosa, and in the corolla has some 

 distant resemblance to V. Golensoi. It may prove to be an hybrid between 

 these two species. 



Hab. — Head waters of the River Rakaia. 



Gentiana Novce Zelandice, Armstrong, n. s. 



Root slender, annual ; stems nximerous from the root, ascending, about 

 6 inches high, very slender, rather leafy, many-flowered, black when dry. 

 Leaves linear-spathulate, linear-oblong, or spathulate-oblong, \ to | inch long. 

 Flowers about ^ inch long, pale yellow, on slender pedicels; calyx rather 

 deeply divided ; lobes shorter than the corolla, liu ear-acute ; corolla-lobes, 

 ovate-oblong, acute. 



Hab. — Sources of Rangitata River, Armstrong.
