of sandy loam and peat, but they do not require to be watered 

 so freely as many other plants of this order ; for if they are 

 watered too much over their leaves, it is certain to kill them. 

 The very young tops taken off and made into cuttings, and 

 planted in a pot of sand, with a bell-glass placed over them, are 

 not difficult to root, if the bell-glasses are taken off and wiped 

 regularly to prevent damp. They are all elegant plants when in 

 flower. 



XLV. HA'LLIA (named after Berger Martin Hall, a pupil 

 of Linnaeus, and the student under whose name the thesis called 

 Nectariaflarum stands in the Amcenitates Academica). Thunb.

LIN. SYST. Monadelphia, Decdndria. Calyx 5-cleft, with 

 the segments about equal. Keel obtuse. Stamens monadel- 

 phous, with the sheath complete. Legume compressed, mem- 

 branous, 2-valved, 1 -seeded. Cape herbs er subshrubs, with 

 simple leaves and with the stipulas adhering to the petioles, and 

 purple flowers standing on solitary axillary pedicels. This 

 genus is allied to Psoralea or Anthyllis, not to Hedysarum. 



1 H. ALA'TA (Thunb. fl. cap. 593.) stem 2-edged ; stipulas 

 rather decurrent, adnate to the petioles and longer than them ; 

 leaves lanceolate or oblong, younger ones rather villous and 

 complicated, adult ones glabrous ; flowers on short pedicels, 

 ultimate ones according to Thunberg disposed in a terminal 

 raceme, I/ . G. Native of the Cape of Good Hope beyond 

 Cape Town, a little to the westward. 



Winged-stemmed Hallia. Fl. July, Aug. Clt. 1818. PI. 1 ft. 



2 H. FLA'CCIDA (Thunb. 1. c.) stem filiform, trigonal at the 

 apex ; stipulas ovate, acute, striated, hardly adnate to the petioles 

 at the base, and rather longer than them ; leaves lanceolate, mu- 

 cronate, glabrous ; peduncles 1 -flowered, length of leaves. I/. . G. 

 Native of the Cape of Good Hope. The stipulas according to 

 Thunberg are reflexed, but in the specimen they are obviously 

 erect.

Cult. The species of Hallia are very pretty plants, with 

 purple flowers ; they thrive well in a mixture of sandy loam and 

 peat, and young cuttings strike freely in sand under a bell-glass, 

 or they may be raised from seeds, which sometimes ripen. 



XLVI. HEYLA'NDIA (in honour of M. Heyland, an artist 

 employed by De Candolle). D. C. leg. mem. vi. prod. 2. 

 p. 123. 



LIN. SYST. Monadelphia, Decandria. Calyx 5-cleft, with the

 Legume compressed, 1 -celled, 1 -seeded. East Indian herbs or 

 subshrubs, slender, dichotomous, and hairy, without stipulas. 

 Leaves on short petioles, cordate, roundish. Flowers axillary,

 vered with long scattered hairs ; leaves on very short stalks,

Cult. The culture and propagation of this genus is the same 

 as that recommended for Hallia, but being stove plants require 

 heat.

 tanet ; the pods of this genus are inflated, and the seeds rattle 

 when the pods are shaken.). Lin. gen. 862. Gaert. fruct. 2.

LIN. SYST. Monadelphia, Decdndria. Calyx 5-lobed, some- 

 what bilabiate, upper lip bifid, lower one trifid. Vexillum 

 large, cordate. Keel falcate, acuminated. Filaments all con- 

 nected with the sheath, cleft in front. Style bearded laterally, 

 pubescent. Legume turgid, with the valves ventricose, usually 

 many-seeded, pedicellate. Herbs or subshrubs, with simple or 

 palmately compound leaves, these last have usually 3 leaflets, 

 very rarely 5 -foliate. Flowers usually yellow, with small brac- 

 teas along the pedicels, or at the base of the calyx. The 

 greater number of the species being not sufficiently known, the 

 whole are disposed in an artificial order.
