118 XXIII. LEGUMINOSAE. [Clianthus. 



5. CLIANTHUS, Banks and Sol. 

 Calyx campanulate, 5-toothed. Standard sharply reflexed, acuminate ; 

 wings oblong or lanceolate, about half the length of the keel, auricled at the 

 base ; keel boat-shaped, produced into a long curved point. Ovary stipitate, 

 many-ovaled ; style subulate, incurved, ciliated below the apex. Pod stipitate, 

 oblong-acuminate, terete, falcate, 2-valved, beaked, turgid ; seeds many. Herbs. 

 Stems and branches woody below. Leaves alteraate, unequally pinnate ; leaf- 

 lets in many pairs. Stipules small. Flowers large, crimson, in pendulous 

 racemes. 



A small genus of beautiful flowering-plants, comprising, besides the present species, whioli is 

 endemic, one or perhaps two from Australia, and one from the Island of Ceram. 



1. C. puniceus, Banks and Sol. ex Lindl. in Bot. Reg. t. 1775. A 

 much - branched suffruticose silky pubescent shrub, 3ft.— 6ft. high. Leaves 

 unequally pinnate ; leaflets sessile, in 8—14 pairs, linear-oblong, obtuse refuse or 

 apiculate. Branches spreading. Racemes many-flowered. Flowers bright- 

 scarlet. Standard ovate, acuminate ; wings lanceolate, falcate, acute or sub- 

 acute, less than half the length of the keel ; keel falcate, acuminate ; style 

 wholly included in the keel. Pod turgid, many-seeded. 



Var. maxlmus, (sj).), Col. in Trans. N.Z.I, xviii. (1885) 294. Leaflets large, sometimes IJin. 

 long, often shining. Flowers rather smaller. Standard broadly ovate, acuminate, often with a dark 

 blotch at the base ; wings oblong, broad, rounded at apex. — Lindl. in Bot. Reg. t. 1775; A. Cunn. in 

 Trans. Hort. Soc. Ser. II. i. (1835) 521; Precurs. n. 572; Hoolr. f., PI. N.Z. i. 49; Handbk. .52; 

 Banks and Sol. MSS. Donia punicea, Don., Syst. Gard. ii. 468. 



NORTH Island : Great Barrier Island, T. E. On one or two islets ofi the East Coast, and 

 inland, Bishop Williams ! Near Waimarama, Nairn. Collected by Banks and Solander at Motu- 

 arohia, Bay of Islands, Anaura, and Tolaga Bay, East Cape, according to their MSS. Also at 

 Mercury Bay, as stated by Cunningham. Collected also at the Thames in 1869, but is certainly 

 extinct in that locality. Formerly cultivated by the Maoris. Kowainguta. Eaka. Aug. to Oct. 



The shape of the standard and wings diflers materially in different plants. Banks and 

 Solander's fine plate represents exactly G. maximus, Col., with the wings broadly rounded at the 

 apex ; their collection, however, contains specimens with very narrow pointed wings. There are 

 all degrees of difierence between the two forms ; but either form of wing may be associated with 

 either form of standard. Mr. Oolenso's interesting paper should be carefully read, although to Sir 

 Joseph Hooker and myself the differences pointed out appear to pass into each other by insensible 

 gradations. 



6. SWAINSONA, Salisb. 



Calyx campanulate; teeth 5, nearly equal. Standard nearly orbicular^ 

 shortly clawed; wings auricled at the base, falcate, free. Upper stamen free. 

 Ovary sessile or stipitate, many-ovuled ; style incurved, slender, bearded on the 

 upper surface ; stigma minute. Pod inflated or turgid, membranous or coria- 

 ceous, acute, several-seeded. Herbs, with prostrate erect or climbing stems, 

 rarely suffruticose. Leaves unequally pinnate; leaflets usually numerous. 

 Stipules deciduous. Flovrers in axillary racemes. 



Species, about 30, all restricted to Australia, except one endemic in New Zealand. 



1. S. Novae-Zelandiae, Hook.f., Handbk. N.Z. Fl. 51. Stem forming 

 slender rhizomes below; much branched above; 2in.-5in. high. Branches aud 

 leaves clothed with silky pubescence. Leaves lin.-2in. long; leaflets in 6-8 

 pairs, narrow-obovate or oblong, rounded or retuse. Peduncles 3-8-flowered.
