388 KEY TO BRITISH RUBI.

the patent hairs. Sep. embracing fr. 



Dr. Focke prefers keeping this as a distinct species, with R. 

 adornatus P. J. Muell. as a "hill-country" var.; but he admits that 

 " a hard and fast limitation of the forms of R. hystrix appears to be 

 impossible." "The typical form," he says, " originally found by 

 Weihe at Menuighiiffen, in the Minden district, has crowded very 

 unequal prickles on the barren st., narrow Its., and orbicular pet."; 

 while near Bremen he finds " a similar strongly-armed form with 

 broader 1. and narrower pet.," and "other forms occur here and 

 there," approaching adornatus. 



c. R. Lingua Bab. Brit. Rub. p. 175. — Very near hystrix; but 

 " the term. It. is more abrupt, and the edges of all the Its. are much 

 more finely dentate, with the principal teeth patent, but the others 

 directed very decidedly towards the apex of the It." Pan. "very 

 loose, consisting almost wholly of long simple ped." Okehampton, 

 Dev. I have seen this also near Launceston, Cornw., and think it 

 a well-marked var. Its large prickles are more decidedly separated 

 off from the rest of the st. -armature than in other forms. 



d. infccundus. — I suggest this as a varietal name for a woodland 

 plant very abundant in Heref., and several West and Mid. Engl, 

 counties. In general colouring, in the very marked sep., and in 

 the clothing and armature of pan.-rachis and ped. I can see no 

 difference between it and the type ; but the st. -prickles are usually 

 much smaller, and in many cases nearly subulate from a long 

 tubercular base ; the st.-armature generally is reduced in quantity^ 

 often consisting chiefly of crowded minute acicles and scattered 

 hairs; the 1. are chiefly 5-nate-pedate, and the Its. narrow, softly 

 hairy beneath, and more sharply though usually not deeply serrate ; 

 the lax pan. is narrowly pyramidal, and frequently the floral and 

 reproductive organs seem imperfectly developed, the sep. soon 

 clasping the half-withered pet., and the fr. seldom produced. I 

 cannot believe it a hybrid. Here, I suspect, should come Mr. 

 BagnalPs plant from Crackley Wood, near Kenilworth, which 

 £rof Babington in 1889 (v. B. E. C. Rep. p. 251) thought might 

 be the R. myriadenophorus Rip., and which he would place as a var.

 mostly dejiexed L. chiefly 5-nate-pedate. Lts. irregularly and doubly

 prickles on petioles, petiolules and midribs ; term, narrowed very 



gradually to the acuminate point, usually broadest a little below the 



middle, and thence rounded to the entire or more or less cordate 

 base ; intermediate with patent or divaricate petiolule ; bas. con-
