nearly naked ; hairs patent, not clustered ; aciculi and setse 

 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. Leaflets rather thick, dark green, rough and pilose 

 on both sides, pale with more numerous haii\s on the veins 

 beneath, finely dentate-serrate, nearly flat with the edge 

 slightly turned upwards ; lower shortly stalked, obovate- 

 oblong, cuspidate j intermediate larger, stalked, obovate, 

 abruptly cuspidate ; terminal with a rather long stalk, 

 broadly obovate with a cordate base, abruptly cuspidate; 

 petioles and midribs with few small deflexed prickles be- 

 neath; stipules linear-lanceolate. 



Flowering shoot long, from fuscous scales, slightly angular, 

 green but tiuged with purple, hairy. Prickles few, generally 

 very small and short, yellow, sometimes long, straight and 

 declining, slender, from an enlarged and compressed base. 

 Leaves ternate or quinate. Leaflets nearly equally hairy on 

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

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

 externally; of the quinate leaves the lower leaflets are small 

 and oblong, intermediate and terminal broadly obovate and 

 cuspidate; petioles and midribs with few slender declining 

 prickles beneath ; stipules linear-lanceolate. Panicle narrow, 

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

 many unequal red setse and aciculi; branches mostly axillary, 

 ascending, falling short of the leaves, bearing a corymb of 

 1-3 long-stalked flowers; summit corymbose. Sepals lan- 

 ceolate, acuminate, with a long linear point, hairy, felted, 

 setose, and greenish, with a narrow margin of white felt 

 externally, whitely felted but purple at the base within,
