RUBUS. 101 



I. 5-nate thin green on both sides pilose beneath coarsely and 

 doubly dentate-serrate, term. It. broadly obovate subcordate be- 

 low cuspidate, pan. long lax leafy below hairy with short few- 

 flowered patent subeorymbose branches, rachis wavy, prickles 

 slender declining, sep. long-pointed hairy tomentose. — R. calva- 

 tus Blox; — St. green, becoming quite glabrous ; a few subse^ijile 

 glands ; setae and aciculi very few. L. very slightly pilose above, 

 hard and rough beneath. Rachis of fl. -shoot wavy. The ori- 

 ginal R. Salteri has a very few sunken setae on its panicle and 

 calyx ; fl.-shoot with a nearly straight rachis ; branches of pan. 

 more corymbose ; fr.-sep. erect ; prickles fewer on all parts 

 than the typical R. calvatus. But they seem to be the extremes 

 of one species. — Hedges. Sh. VI. — VIII. E. 



21. R. macrophyllns (W. and N.); st. arched or prostrate an- 

 gular with scattered patent hairs, prickles short rather slender 

 scarcely exceeding the longitudinal extent of their large base 

 much declining, 1. 5-nate thin green and tomentose or pilose be- 

 neath, term. It. elliptic-obovate, pan. compound rather elongate 

 hairy tomentose with short sunken setae, branches axillary race- 

 mose ascending, prickles slender much declming from a large 

 base, cal. hairy tomentose.— R. G. 12. E. B. 2625 ? R. Schlech- 

 tendalii Bab. R. amphficatus Lees. — St. thick, very long, pur- 

 plish green. Prickles usually singularly thick at their base hut 

 the upper part slender, sometimes rather small, yellow. Short 

 aciculi and setae not unfrequent. L. sometimes much rounder 

 and cuspidate. — Hedges and thickets. Sh. VII. VIII. E. I. 



22. jR. Sprengelii (Weihe) ; st. prostrate round hairy, prickles 

 many unequal from a large compressed base deflexed, 1. 3 — 5- 

 nate-pedate green on both sides distantly pilose beneath, term. It. 

 elliptical acuminate, pan. lax leafy below hairy tomentose setose, 

 branches divaricate few-flowered the lower axillary ones often long 

 and decompound, prickles slender few, sep. erect-patent hairy to- 

 mentose long-pointed. — a. JJ.Borren (Bell Salt.); st. thick strong 

 with many often very unequal prickles and some setae and aciculi, 

 1. mostly 5-nate, pan. often corymbose or when the branches are 

 shorter subthyrsoid. — ^. R. Sprengelii (Weihe) ; st. slender with 

 small prickles and subsessile glands, 1. mostly 3-nate, pan. lax 

 few-flowered subeorymbose. R. G. 10. — These forms are quite 

 connected by intermediate states ; sometimes a few setae occur 

 on the St. of 0, they are found on the panicle of both. — Woods 

 and thickets. Sh. VI. VII. E. 



V. Glandulosi. St. with many hairs glands setae and aciculi 

 passing more or less gradually into scattered prickles. 



A. L. 5-nate {rarely 3-nate) ; basal Its. stalked, not imbricate. 

 Prickles on st. passing abruptly into aciculi and seta. 



23. R. Bloxamii (Lees) ; st. prostrate angular or furrowed.
