2. H. CUrta. Erect, lft.-2ft. high, sparingly branched. Branchlets 

 elongated, slendei', subterete, the upper portion compressed, striated. Leaves 

 not seen. Racemes distant, 6— 10-flowered. Rhachis silky, elongating after the 

 flowers have fallen ; pedicels short, puberulous or silky. Flowers Jin. long. 

 Calyx puberulous or pubescent, campanulate, 2-bracteolate at the base ; teeth 

 acute, villous within. Standard broadly obovate, broader than long, shortly 

 retuse, margins revolute ; wings with a large callosity at the auricle ; keel 

 with a short claw. Ovary pubescent or silky ; ovules 4. Pods -J-in. long, 

 pendulous, turgid, glabrous when mature, oblong-obovate ; beak short, oblique. 

 Seeds 2—i, mottled. — Carmichaelia curta, Petrie in Trans. N.Z.I, xxv. (1892)

The flowers are larger than in G.juncea, and the standard is less reflexed. The callosity at 

 the base o£ the wings is unique in the genus, and is not found in Carmichaelia or other allied 

 New Zealand genera. 



3. H. juncea. Erect, lft.-2ft. high, rarely prostrate. Branchlets strict 



or curved, almost terete or more or less compressed, grooved. Leaves not seen. 



Racemes 2-8-flowered. Rhachis and pedicels silky ; pedicels very short. Bracts 



and bracteoles linear, acute, silky, glabrous or puberulous. Flowers minute. 



Calyx turbinate ; teeth subacute, silky. Standard exceeding the keel, broader 



than long ; wings shorter than the keel. Ovary pubescent or glabrous, 2—4- 



ovulate. Pod lin.— l^in. long, glabrous or pubescent, broadly oblong, turgid 



or almost inflated, 1— 3-seeded ; beak strongly curved upwards, slender, oblique ; 



valves very thin. — Carmichaelia juncea, Col. ex Hook, f., Fl. N.Z. i. 51 ;

This was originally described as a small tree, "8ft.- 14ft. high," but I have not seen specimens 

 more than 2ft. high. The beak of the Otago plant usually forms nearly a right angle with the axis 

 of the pod. Unfortunately, I have not had the opportunity of examining flowers of the North Island 

 plant, and, as the original description is very imperfect, it is possible that two species may be con- 

 fused under M. juncea. 



4. H. prona. A small species, with prostrate stems and branches closely 

 appressed to the ground, 4in.-12iu. or more. Branchlets Jgiu.-Jg-in. broad, 

 compressed, rarely with few transverse articulations. Leaves unifoliolate or 

 pinnately 3-5-foliolate, silky ; terminal leaflets much the longest, narrow-cu- 

 neate-oblong, emarginate. Flowers small, in dense 3-7-flowered racemes. Rha- 

 chis silky; pedicels shoi't. Calyx campanulate; teeth acute. Standard retuse; 

 wings shorter than the keel. Pods Jin. long, broadly oblong, turgid, with a 

 short upturned beak, which forms a right angle with the pod, 1-seeded. — Car- 

 michaelia prona, T. Kirk in Trans. N.Z.I, xxvii. (1891.) 350.

Most nearly related to H. juncea, from which it is distinguished by the prostrate habit, com- 

 pressed branches, and numerous leaves.
