T. Kiuk. — A Revision of the New Zealand Gentians. 339 



usually coriaceous or fleshy, shining obovate- or spathulate- 

 oblong or linear-spathulate ; cauline smaller, Jin.-Hin. long. 

 Flowers on slender pedicels crowded towards the tips of the 

 branches, sometimes forming lax corymbs, rarely trichotomous. 

 Calyx divided nearly to the base, equalling the corolla, rarely 

 longer, oblong or oblong-spatlralate, obtuse or rounded at the 

 apex, broad ; ovary stipitate. Stems narrowly winged above.

Hab. Auckland Islands; sea-level to 900ft. 



One of the most beautiful plants in the flora, the corollas 

 varying in colour from a pure waxy white to white with a 

 vertical red stripe, purple, reddish-purple, and violet. It is 

 extremely variable in habit and luxuriance, according to the 

 nature of the habitat in which it is growing. Three principal 

 forms may be recognized : — 



Forma a, suberecta. Stems decumbent, ascending, slender, 

 6in.-12in. high or more. Leaves spathulate-oblong, petiolate 

 or rarely sessile by a broad base. Flowers usually in lax 

 corymbs on long or shore pedicels. Calyx segments broadly 

 oblong. 



Hab. Sheltered places on the hills up to nearly 1,000ft. 



Forma b, ccrina. Stems prostrate or trailing. Leaves 

 very thick and fleshy, shining, obovate or spathulate-oblong, 

 narrowed below, or rarely sessile. Flowers smaller, often 

 sunk amidst the terminal leaves. Calyx segments sometimes 

 slightly recurved. 



Hab. On maritime rocks and in places exposed to heavy 

 spray. 



Forma c, concinna. Usually annual. Stems numerous, 

 lin.-3in. long, densely crowded. Leaves all linear-oblong, 

 obtuse, Jin.— |in. long. Flowers solitary, small, in axils of 

 upper leaves. Calyx segments shorter than the corolla. 



Hab. On masses of Trichocolea tomentella and other He- 

 paticae. 



The three forms mentioned pass into each other by the 

 most insensible gradations, although the extremes present a 

 wide difference. Sir Joseph Hooker agrees with me in con- 

 sidering it impossible to separate G. concinna specifically. 



9. G. antarctica, n.s. 



Annual ; whole plant minutely verrucose. Stem stout, 

 erect, excessively foliaceous, 3in.-10in. high. Eadical leaves 

 lin.-2in. long, rather fleshy, oblong or oblong- spathulate or 

 lanceolate, narrowed into flat petioles, 3-5-nerved ; cauline 

 smaller, oblong-spathulate, petioles short and broad, equal- 

 ling the blade or shorter, membranous when dry. Flowers
