GENTIANEÆ.
[Gentiana.

ceous, rather thick and fleshy when fresh. Cauline leaves one or two pairs, seldom more, ¾–2 in. long, linear-lanceolate or linearoblong, sessile. Flowers large, ½–¾ in. diam., white, in large compact terminal umbels or cymes 2–6 in. diam. or more; pedicels slender. Calyx short, often less than one-half the length of the corolla, campanulate, divided from ⅓ to ½ way down, rarely more; lobes lanceolate-deltoid, acute or acuminate. Corolla divided about two-thirds way down; lobes broadly oblong, rounded at the tip. Ovary stipitate.—G. saxosa var. y, Hook. f. Handb. N.Z. Fl. 191. G. pleurogynoides var. rigida. Kirk. in Trans. N.Z. Inst. xxvii. (1895) 335.

South Island: Mountain districts from Nelson to Otago, abundant. 1000–4000 ft. January–March.

A very handsome plant, in its ordinary state well distinguished by the stout usually simple and almost naked stems, long and narrow crowded rosulate radical leaves, and dense cymes or umbels of large white flowers, the calyx of which is broad and short, with lanceolate-deltoid acute lobes. Mr. Brown informs me that it corresponds with the G. saxosa var. y of the Handbook, and I suspect that it also includes a part of the G. pleurogynoides of the same work. At any rate, it is the plant which New Zealand botanists have been accustomed to call G. pleurogynoides. The true G. pleurogynoides was founded on Tasmanian specimens, and has not yet been satisfactorily matched with any New Zealand plant.


6. G. Townsoni, Cheesem. n. sp.—Perennial; root slender, woody, often branched at the top. Flowering stems usually single, rarely 2 or 3 from the root or branched from the base, erect, slender, wiry, 6–20 in. high. Leaves almost black when dry; radical very numerous, crowded at the base of the stem, spreading or ascending, small for the size of the plant, ½–1½ in. long, ⅙–⅓ in, broad, ovate-lanceolate or trowel-shaped to linear-lanceolate, narrowed into a rather slender petiole, coriaceous or almost fleshy, subacute or obtuse. Cauline leaves in 2–5 remote pairs, ascending, lanceolate or oblong-lanceolate, sessile, subacute. Flowers white, large, ¾ in. diam. or more, in 5–12-flowered terminal cymes or umbels; pedicels slender; bracts usually whorled. Calyx about half the length of the corolla, cut about three-quarters way down; lobes lanceolate, acute. Corolla deeply divided; lobes broadly oblong, rounded at the tip.—G. saxosa var. pleurogynoides, Hook, f. Fl. Nov. Zel. i. 178, in part. G. pleurogynoides, Hook. f. Handb. N.Z. Fl. 190, in part (not of Griseb.).

South Island: Nelson—Bidwill (n. 67 in Herb. Kew, fide N. E. Brown); coast ranges near Westport, Mount Frederic, Mount Rochfort, Mount Buckland, &c., Townson! Sounds of the south-west coast of Otago, Lyall (fide N. E. Brown). 1000–4000 ft. January–March.

A very beautiful plant, easily recognised by the tall slender strict stems, small uniform crowded leaves, which are almost black when dry, remote ascending cauline leaves, and rather dense umbels of large flowers. I have seen no specimens but Mr. Townson's, from which the above description is drawn up;
