but also of the great obligation under which I feel all British botanists 

 to be to him, for all that he has done to elucidate our Flora. The 

 following is a description of 



Rnhus Bahingtonii. Stem very long, arched, terete and channel- 

 led, slightly glandulose and hairy, hispid with numerous short, thick 

 prickles, which pass insensibly into setae. Leaves ternate, rarely qui- 

 nate, green and glabrous on both sides ; leaflets rhomboido-cordate, 

 cuspidate, irregularly and doubly crenato-serrate, serratures mucro- 

 nate ; 2yetioles and pedicels prickly and setose ; stipules linear, hairy. 

 Panicle leafy and much branched; primary rachis clothed in the 

 lower part as the shoot ; the upper portion, branches and peduncles 

 tomentose, prickly and setose ; glands not numerous. Leaves of the 

 panicle ternate or simple, entire at the base, with raucronate crena- 

 tures towards the apex. Bracteas foliaceous to the summit, broadly 

 lanceolate, hairy and glandulose. Calyx broadly lanceolate, cuspi- 

 date, hairy. 



This species is by far the largest Rubus I have ever seen, but I am 

 unable to speak of its exact dimensions, not having measured it. Its 

 hispid stem would place it as a near ally of R. rudis {W. Sf N.), while 

 its style of inflorescence would associate it with Koehleri or fusco-ater, 

 and its tomentose rachis and peduncles with R. leucostachys and its 

 allies. To see a bramble of this extraordinaiy size with ternate leaves 

 is not a little remarkable, and what is still further so is, that the few 

 quinate leaves which did exist, were on the smaller and weaker shoots. 

 The leaves are perfectly free from hairs above, and almost perfectly 

 so, and consequently green beneath ; their coarse crenatures too have 

 a remarkable aspect, quite different from any other Rubus. The pa- 

 nicle is enormous, being fully two feet in length, and in some instan- 

 ces considerably more. Notwithstanding the enormous size of the 

 other parts of the inflorescence, the fruit is very small, and composed 

 of minute black drupes. The stem, though grooved, is not angled, 

 the prominences left by the grooves being rounded. It is certainly 

 more hispid than any other Rubus I have seen. 



From R. rudis and its other allies — for in this group its hispid stem 

 certainly places it — it may readily be distinguished by the broad leaf- 

 lets, instead of the narrow jagged ones of those species; from R. 

 Koehleri and its allies by the paucity of hairs and glands ; lastly, from 

 R. leucostachys and its congeners, by the presence of glands and 

 setae ; and from all these by the ternate leaves, with their crenate 

 margins.
