joint ; the ribs more or less broken into irregular coarse warts 
or granules. — The pubescence of the fruit affords a very obvious 
but the only well-marked or perhaps altogether permanent di- 
stinction between this andvar. j3. The two however grow con- 
tinually intermixed ; so that the differences between them can- 
not be ascribed to soil or situation.

though rather the rarer in Madeira. March-May. — Habit, size 
and general characters precisely as in a : but besides the smooth- 
ness of the fr. from its earliest stage, the lower 1. are more 
acute and not lyrate but merely sinuate and toothed. In one 
Porto-Santan specimen the 1. however are decidedly lyrate or 
pinnatifid, and the pi. is altogether smoother and the root more 
woody or perennial-looking than usual ; the pouches being also 
merely ribbed and not verrucose or rugose, though with the 
ordinary slender elongated style. — R. perenne (L.) Berg, and 
R. orientate DC. with which a. and /3. have often been respect- 
ively confounded, are both much taller larger more robustly 
growing and more upright ph, 2 or 3 ft. high or more, with 
long erect not straggling patent or deflexed branches, and much 
larger foliage : the 1. in R. perenne L. being 6-8 in. long, lyrate- 
pinnate, with 3 or 4 pairs of pinnae and a large terminal lobe ; 
and in R. orientate 1)C. a foot long, very obtuse, and merely 
sinuate with obtuse lobes and sinuses. In R. perenne also the 
root is decidedly perennial, sending up fresh stems annually 
from the old woody stock, which is never the case even by 
accident with the Madeiran pi.
