large straggling plant with strong but usually prostrate steins. 

 The thin, singularly broad, and angular leaves, and the deeply 

 furrowed stem would perhaps be in themselves sufficient to di- 

 stinguish it from the other " Nitidi." 



4. R. imbricatus, Hort. 



Mr. Hort has published a full description of this plant (Ann. 

 Nat. Hist. Ser. 2. vii. 374), and it is therefore unnecessary to 

 notice it further in this place.

Stem arched, nearly round, slightly angular with flat sides 

 towards the end, densely hairy near the base but less so towards 

 the end ; hairs patent, not clustered ; aciculi and setae few or 

 none ; subsessile glands few ; prickles chiefly on the angles of 

 the stem, few, usually small, slender, conical from an enlarged 

 base, patent or very slightly declining. Leaves quinate, rather 

 thick, green rough and pilose on both sides, hairs more nume- 

 rous on the under side, finely dentate-serrate; petiole midrib 

 and primary veins yellow or reddish beneath, with a few small 

 deflexed prickles ; lower pair of leaflets shortly stalked, obovate- 

 oblong, cuspidate ; intermediate pair larger, stalked, obovate, 

 abruptly cuspidate; terminal leaflet with a rather long stalk, 

 broadly obovate with a cordate base, abruptly cuspidate. Sti- 

 pules linear-lanceolate. 



Flowering shoot long, with long fuscous scales at its base, 

 slightly angular, green but tinged with purple, hairy; prickles 

 few, generally very small and short, yellow, sometimes long, 

 straight and declining but slender, their base enlarged and com- 

 pressed. Leaves ternate or quinate, nearly equally hairy on both 

 sides, rather paler beneath ; leaflets of the ternate leaves nearly 

 equal, oblong or obovate, finely serrate, lower pair often lobed 

 externally ; on the quinate leaves the lower pair of leaflets is 

 small and oblong, intermediate pair and terminal leaflet broadly 

 obovate and cuspidate. Petioles and midribs with few slender 

 declining prickles. Stipules linear-lanceolate. Panicle narrow, 

 very lax, leafy except at the top, hairy and tomentose, often with
