M. @LAUCIFOLIUS. Kellogg, under Rubus. 
M. NIGERRIMUS. Rubus hesperius, Piper, Eryth., v. 103. 
M. Micuiaanus. More sparsely and feebly armed than M 
occidentalis; leaflets longer, narrower, less incised ; the odd one 
lance-oblong or narrow-ovate, 24 inches long, all merely pale 
beneath, scarcely white even when half grown: pedicels with 
few and reduced prickles but a rather copious short glandular 
hairiness. 
Woods near the Agricultural College, Michigan, C. F. Wheeler, 
1895. 
M. BERNARDINUS. Rather low, excessively and stoutly 
prickly even to the midvein of the leaflets: foliage small, deep 
green above, white beneath; odd leaflet 14 inches long, quite as 
wide, broadly ovate to deltoid-ovate, somewhat 3-lobed now and 
then, otherwise doubly serrate-dentate: pedicels with few strong 
prickles and a dense glandular short indument. 
Mill Creek Falls, San Bernardino Mountains, Cal., S. B. 
Parish, June, 1901, n. 5046. 
ParMENA. Raspberries, but with the habit of upright Black- 
berries, though less prickly, sometimes almost unarmed. Leaves 
3-foliolate, or some simple. Flowers few or solitary, large, with 
rose-red long petals: calyx 5-cleft, very closely reflexed under 
the fruit; this large, of very many drupelets. Pyrenes strongly 
favose-pitted, but low-keeled on the back. 
P. SPECTABILIS. Pursh, under Rubus. 
P. Menziesin. Hook., x = 
CARDIOBATUS. Technically a true Blackberry, small, trailing» 
very prickly, even to the round-cordate simple foliage. Stipules 
foliaceous. Flowers solitary in the leaf-axils, short-pedicelled : 
calyx quite divided, the sepals very unequal, one large, often 
foliaceous, more or less enfolding the narrower, the whole calyx 
erect in fruit, enfolding the very small fruit of few drupelets. 
Petals rose-red, showy.
