ROSACEA. 191 



bington's 'Manual/ p. 101, 2nd ed. — Stem angular,, furrowed, 

 very slightly hairy, shining, prickly; prickles nearly straight 

 and nearly horizontal, those on the petioles deflexed, all much 

 compressed and dilated at the base ; leaflets large, rounded, with 

 coarse, unequal, spreading teeth, green on both sides, and rather 

 more cordate at the base; flowers in very lax leafy corymbs; 

 sepals with longish, filiform points. 



Var. amjjlificatus, Lees. — Stem hairier, with more deflexed and 

 rather stouter prickles ; leaflets narrower, with more erect teeth ; 

 panicle not very open ; sepals more acuminate. — Note. The leaf- 

 lets in this variety vary between broadly obovate and cuneate ; 

 the sepals are elongate, and more tapering than in the preceding 

 varieties. A var. of R. macrojjJiyllus. (See Babington's 'Manual,' 

 p. 101, 4th ed.) 



The forms in this group, viz. rhamnifolius, nitidus, etc., are 

 distinguished by petiolate lower leaflets, which are always more 

 or less declinate. 



R. latifolius, Bab.— L.c. (8). (A. 3. C. 3. Lat. 54-57°.)— 

 Stem angular, furrowed, glabrous, purplish or green ; leaflets very 

 large, cordate at the base, rounded, acuminate, very broad ; lower 

 pair of leaflets overlapping. — See ' Phytologist,' vol. iv. p. 969, 

 where Mr. Baker informsus that it is a connecting link between 

 R. corylifolius and R.nitidus, as we understand the passage. He 

 says that it is probably a luxuriant state of the former.
