328 XXXIX. COMPOSITAE. [Cotula. 



3-4-toothed.. eglandular; achenes (immature) linear-oblong, cuneate. Male 

 florets trumpet-shaped ; mouth broad, 4-lobed. 



SOUTH Island : in swamps at Woodend, Southland, T. K., Nov. (1887). 



Better speeimens of this curious little plant are much wanted, the material collected not being 

 sufficiently advauoed. The female scapes seen are very slender. 



19. C. pulchella, n. s. Stems slender, rather wiry, lin.— lOin. long or 

 more, hairy. Leaves ^in.-2Jin. long, glabrate or pilose, membranous, linear- 

 oblong, obovate, obtuse, pinnatifid or pinnate at the base ; segments in 6—9 pairs, 

 narrow, deeply 2— 4-toothed at the tips ; teeth sometimes piliferous ; petiole 

 long, slender. Heads unisexual ; peduncles axillary, usually shorter than the 

 leaves. Female : Jin.— Jin. in diameter ; involucre hemispherical ; involueral 

 bracts in 3 rows, outer orbicular-ovate with erose purple or green margins, 

 glabrate or pubescent, inner linear-oblong ; corolla eglandular, ovoid-conical, 

 about one-third as long as the ovary ; mouth denticulate ; achene stipitate, 

 slightly curved, turgid, plano-convex. Male : rather smaller ; corolla funnel- 

 shaped, 5-lobed. 



. SOUTH Island: in boggy ground near Lincoln, Canterbury. Invercargill : mouth of the 

 Oreti Biver ; the Bluff Hill. STEWART Island : rare and local, T. K. 



Nearly related to G. dioica, but the leaves are much longer and more deeply divided, never 

 flaccid ; the female corolla is longer and narrower, and the stipitate achene is turgid and convex at 

 the back. Occasionally the heads are slightly heterogamous, one or two female florets being found 

 in the outer row of male florets, and more rarely a male floret in the centre of the female head. In 

 minute specimens linear-oblong bracts are not developed in the involucre and the leaf-segments are 

 often entire. 



20. C. dioica, Hook. /., Handbk. 143. Stems creeping, usually rather 

 robust, 3in.— 12in. long. Leaves rather flaccid, tufted or solitary, glabrous ; 

 petiole Jin.— 2in. long, obtuse, crenate-serrate or lobed or semipinnatifid ; lobes 

 serrate on the upper margin or entire ; teeth acute. Scape naked, longer or 

 shorter than the leaves, pubescent. Heads unisexual, Jin.— Jin. broad. Female : 

 involueral bracts in 3 rows, pubescent, broadly ovate to oblong-orbicular ; 

 margins erose, purple or green, the innermost linear-oblong ; receptacle slightly 

 convex (not conical) ; corolla broadly ovoid or almost orbicular, eglandular, 

 slightly inflated; mouth minutely denticulate; style-arms short. Male: smaller; 

 receptacle usually conical ; corolla funnel-shaped ; mouth broad; stigma discoid; 

 achene broadly obconic. — Banks and Sol. MSS. and Icon. Leptinella dioica, 

 Hook, f., Fl. N.Z. i. 129. 



Var. crenatifolla. Leaves sometimes 3in. long on longer petioles, crenate-lobed or peoti- 

 nately pinnatifid. 



NORTH and SOUTH Islands : from the Great Barrier Island to Southland. Not unfrequent 

 in littoral situations. Var. crenatifolia less frequent in inland swamps. Deo. to Feb. 



21. C squalida, Hook, f., Handbk. 143. Stems slender, creeping, woolly 

 or silky, 6in.-15in. long or more. Leaves lin.-2in. long, linear-oblong, obovate, 

 flaccid, glabrate or silky, pinnatifid, petiolate ; segments usually lax, soft, incised 

 along the upper margin or both. Scapes lin.-3in. long, weak, silky. Heads 

 unisexual. Male : Jin. in diameter ; involueral bracts few, mostly in 2 series.
