axillary, on short pedicels. Calyx 13-15 mm. long, grey-villous ; tube very short ; segments 
lanceolate, not much shorter than the petals ; two uppermost somewhat connate. Standard 
glabrous, 13-15 mm. long. Pod not seen. 
CaPE.—Purpas Valley and Zwarteberg, near Caledon, Ecklon No. 1689. 
This plant is easily recognized by the voluble stem, the very narrow trifoliolate leaves, 
and the solitary axillary flowers with a silky villous calyx. It must take De Candolle’s 
earlier name of R. angustifolia. 
SECT. IV.—POLYTROPIA, Harvey and Sonder, “ Fl. Cap.,” II, 248. 
Stem prostrate or trailing. Leaves pinnate or bipinnate, plurijugate. Flowers 
racemose. 
Series 1.—Leaves pinnately decompound. 
8. R. ferulaefolia, Benth., ex Harvey, l.c. 
Polytropia ferulaefolia, “ Presl. Symb.,” $. 18 ; Psoralea prostrata, “ Linn.,” sp. pl. 762; 
Galega pinnata, Thunberg, “FI. Cap.,” 602; Polytropia umbellata, Hcklon and Zeyher 
No. 1627. 
Prostrate, nearly glabrous. Stipules rather short. Leaves pedately bipinnate, pauci- 
jugate or supra-decompound ; leaflets sessile, narrow-lanceolate or linear, acute at each 
end, varying from about 5-20 mm. long ; common peëiole generally 2-4 cm. long, glabrous 
or nearly so. Peduncles longer than the leaves, bearing a cluster of 5-12 flowers towards 
the apex; pedicels 1-3 mm. long. Flowers viscoso-pubescent. Calyx with lowest segment 
conspicuously narrower than the rest. Standard 7-9 mm. long. Pod 12-16 mm. long, 
subfalcate or nearly straight, nearly glabrous. 
CAPE.—(ommon on the Cape Flats and in several parts of the western districts. There 
is a specimen of this in Herb. Sloane, from the Cape, gathered by Oldenland. This will 
certainly be one of the earliest records for this species. 
Series 2.—Leaves sumply pinnate. 
9. R. pinnata, Harvey, “ Thes.,” t. 79; Harvey in Harvey and Sonder, Le. 250. 
Polytropia pinnata, Ecklon and Zeyher No. 1628. 
Whole plant minutely downy, prostrate. Stvpules ovate, striate, deflexed. Leaves 
simply pinnate, bi- to tri-jugate ; terminal leaflet rhomboid-ovate or obovate, 6-12 mm. 
long; lateral leaflets generally elliptic-oblong, impresso-punciate. Peduncles elongate, 
5—6-flowered near the summit. Calyx pubescent, 6-7 mm. long; lowest segment narrower 
than the others, shorter than the petals. Standard yellow, 6-8 mm. long, glabrous or nearly 
so; carina about same length as the standard. Pod not seen, stated by Harvey to be 
the same as in R. ferulaefolia, Benth. 
CapE.—Saldanha Bay, Ecklon and Zeyher No. 1698. 
SECT. V.—EURHYNCHOSIA (incl. Copisma and Orthodanum). 
Stem voluble or rigid. Leaves trifoliolate or rarely unifoliolate. Inflorescence generally 
racemose, but flowers sometimes solitary or subsolitary. Calyx generally shorter than the 
corolla; segments generally lanceolate. Sceds brown, or reddish-brown, or black, not 
blue (in those species in which the seeds are known). |
