GENTIANEÆ.
[Gentiana.

Nouvelle Zélande," which is professedly taken from Forster's manuscripts. Probably the species will be found in suitable localities along the wnole of the western coast, from the Karamea River and Westport to Dusky Sound.


8. G. patula, Cheesem. n. sp.—Usually perennial; root stout or slender. Stems one or several from the root, often decumbent at the base, erect above, simple or branched, 5–20 in. high. Radical leaves usually numerous, 1–3 in long, oblong-spathulate or lanceolate-spathulate, rarely broader and ovate-spathulate, acute or obtuse, coriaceous or slightly membranous. Cauline leaves in 1–5 opposite pairs, oblong or linear-oblong or lanceolate, sessile. Flowers large, ¾–1 in. diam., white, in few- or many-flowered terminal umbels or corymbose cymes. Calyx divided nearly three-quarters way down; lobes linear-oblong, acute or obtuse. Corolla deeply divided; lobes oblong or broadly oblong, rounded at the tip.—G. saxosa var. b, Hook. f. Handb. N.Z. Fl. 191. G. bellidifolia var. patula, Kirk in Trans. N.Z. Inst. xxvii. (1895) 336.

North Island: Tararua Range, Townson! South Island: Abundant in mountain districts throughout. 1000–4000 ft. January–March.

I have much hesitation in advancing this as a distinct species. What may be regarded as the typical state has a stout fusiform root often shortly branched at the top, each branch bearing a crown of oblong-spathulate radical leaves and a flowering stem 6–18 in. high. Dwarf specimens are undistinguishable from G. bellidifolia; but usually the stems are much taller, giving the plant quite a different appearance, and the flowers are much more numerous. Other states approach G. montana, G. corymbifera, and G. Townsoni; and small copiously branched forms appear to pass into G. divisa.


9. G. bellidifolia, Hook. f. in Hook. Ic. Plant. i. 635.—Perennial; variable in size and habit, the typical form with a stout fusiform root crowned with numerous short densely compacted stems, the flowering ones few or many, 1–6 in. high. Radical leaves numerous, crowded, rosulate, ½–1½ in. long, spathulate or linear-spathulate, obtuse, narrowed into a short petiole, coriaceous or fleshy, nerves usually indistinct. Cauline leaves few, distant, linear-oblong to linear-obovate, obtuse, sessile, often recurved. Flowers large, white, ⅔–¾ in. diam. or even more, terminal, solitary or in 2–6-flowered cymes. Calyx one-half the length of the corolla or shorter; lobes linear-oblong to elliptic-ovate, subacute. Corolla divided three-quarters way down; lobes obovate-oblong, rounded at the tip. Ovary shortly stipitate.—Kirk in Trans. N.Z. Inst. xxvii. (1895) 336. G. saxosa var. a, Hook. f. Handb. N.Z. Fl. 191 (not of Forst.).

North and South Islands: Not uncommon in mountain districts from the East Cape, Taupo, and Mount Egmont to Foveaux Strait. 1500–5500 ft. January–March.

A beautiful little plant. The plate in the "Icones Plantarum" represents a somewhat small state, with solitary flowers, but it is otherwise an excellent representation of the species. It appears to pass gradually into both G. patula and G. divisa.
