R. nitidus? var. rotundifolius, Bloxam MSS. in Fasc. of Rubi. 



Stem arching, angular, furrowed when young, glabrous (young 

 shoots slightly hairy), ultimately purple ; prickles moderately 

 numerous, rather short, yellow, from a broad red base, strongly 

 declining or deflexed, nearly equal, confined to the angles of the 

 stem. Leaves quinate-pedate ; stipules almost linear ; petioles 

 and midribs with numerous strong much-hooked prickles ; leaflets 

 finely toothed : teeth pyramidal, glabrous opake and dark green 

 above, ashy white and finely woolly with the veins rather yellow 

 beneath ; terminal leaflet broader than long, cordate below, ab- 

 ruptly cuspidate, sides regularly rounded ; lateral similar but pro- 

 portionably rather longer and almost exactly round ; basal ellip- 

 tical-ovate, rather unequal, overlapping the lateral leaflets, which 

 themselves overlap the terminal leaflet.^ — Flowering shoot long, 

 nearly glabrous ; prickles numerous, rather slender, declining. 

 Leaves nearly all ternate, ashy green beneath ; petioles and mid- 

 ribs beneath with many short hooked purplish yellow prickles ; 

 leaflets like those of the barrea stem, but the lateral ones lobed 

 on the lower side ; stipules very slender. Panicle narrow, com- 

 pound, not setose, very prickly throughout : prickles slender de- 

 clining or deflexed ; rachis pilose below, becoming more hairy 

 upwards, its summit and the peduncles and pedicels tomentose ; 

 about three lower branches axillary, short, racemose-corymbose, 

 about six-flowered j ultra-axillary part compact, cylindrical, ab- 

 rupt, branches short and corymbose ; terminal flower subsessile ; 

 lower bracts leaf-like but inconspicuous, upper trifid hairy and 

 tomentose. Sepals woolly, loosely reflexed from the oblong black 

 pubescent fruit.

Obs. 1. This plant agrees so nearly with the elaborate descrip- 

 tion in the ' Flora Silesise ^ that that work might perhaps be 

 referred to without doubt. In the Silesian plant the panicle is 

 described as " ampla, pyramidata, apice acuta, usque fere ad api- 

 cem foliosa,^^ but it is not so in our plant. In that the under 

 side of the veins of the leaves is said to altogether want any 

 longer hairs — in our plant those veins are clothed with longer 

 hairs. 



Obs. 2. This is an interesting connecting link. The clothing 

 of the panicle and of the young lateral branches from the barren 

 shoot is that of R. nitidus. It diff'ers from that species by its 

 hooked prickles ; very abrupt leaflets opake above and whitish
