branches not spinescent. Flowers small, nearly sessile, in short terminal ra- 

 cemes. Bracteoles minute. Calyx slij^htly silky-puLescent, about 3 lines 

 long, the buds prominently angular, the lobes* persistent. Standard and 

 wings nearly as long as the calyx ; keel rather shortef. Ovary very shortly 

 stipitate, with a short incurved style. Pod almost sessile, ovate, much com- 

 pressed, shorter than tlie calyx.

26. J. piptomeris, Bmlh. A rigid erect broom-like shrub, with virgate 

 branches, silky-pubesceut when young, usually terete and striate, without 

 spinescent branchlets in any specimens seen. Flowers scattered along the 

 ui)per branches. Pedicels much shorter than the calyx, with minute brac- 

 teoles. Calyx minutely silky-pubescent, 3 to 4 lines long, slightly angular in 

 the bud, the lobes deciduous. Petals nearly as long as the calyx, the deeply- 

 coloured keel as long as the yellow standard. Ovary stipitate, with 4 to 6 

 ovules ; style slender. Pod on a rather long stipes when young, but not 

 seen/ully formed.— P/>^fow^m* aphjlla, Turcz. in Bull. Mosc. 1853, i. 258. 



W. AustraHa. Towards Cape Riche, Dnmmond, bik Coll. n, 32. This species 

 doselv reseiubles /. racemosa in aspect, but the calyx is rather more augular in the hud, 

 like the smaller forms of /. angulata. The lobes are deciduous and the keel as lon^ as the 

 standard, as m J. racemosa; and the increased number of ovules distinguishes it from all 

 otlier Jacksomas, ^ 



27. J. angxdata, 5e«/A.^ An Tindcrslirub, witli numerous ascending or 

 erect stems of -J- to 1 ft., silky-pubescent when young, sometimes nearly 

 terete or sulcate, more frequently angular or somewhat flattened, nearly 

 snnple or branchuig, or very flexuose. Flowers few, very shortly pedicellate 

 on some of the lower or intermediate nodes of the more simple and straighter 

 branches. Bracteoles very small. Calyx silky-pubescent, about 4 lines long, 



. the bu.Is very prommently angled, the lobes apparently persistent. Petals 

 shorter tlian the calyx, the keel shorter than the others. Ovary nearly sessile. 

 Pod not seen fully fonncd.— /. Lehmanni, var., Meissn. in PL Preiss. i. 46 

 (as to Dnimniond's specimens).

28. J. macrocalyx, Meism. in Bot, Zdt. 1855, 26. Very near /. an- 

 ^«fo/« but larger in aU its dimensions, the rigid ascending stems often above 

 1 tt. high, the shorter ones divaricately dichotomous, with the ultimate 

 branchlets spinescent, all sulcate or striate but scarcely angular or compressed, 

 the bwer part of the stem occasionally bearing a few obovate-oblong leaves 

 ot ^ to 1 in i lowers few, lateral. Pedicels very short, with 2 small brac- 

 teoles Calyx pubescent, \ in. long, the angles very prominent in the bud, 

 the lobes persistent. Petals not seen perfect, but the standard appears to be 

 at least as long as the calyx. Pod ovate-acuminate, rather turgid, nearly 

 sessile, shorter than the calyx.
