LEGUMINOSAE. 155 
CALOPHAGA. 
(Family Leguminosae). 
Shrubs, or grafted as weeping 
trees: deciduous. Twigs moder- 
ate, terete: cortex exfoliating: 
pith small, roundish, continuous. 
Buds solitary, sessile, concealed 
by the leaf-cushion, often develop- 
ing the first season, with numer- 
ous leaf-base scales evident as the 
bud expands. Leaf-scars_ alter- 
nate, minute, round or elliptical, 
at the top of a greatly dilated 
base that half-encircles the stem: 
bundle-trace 1: stipules large, 
brown. 
Calophaca is one of a consider- 
able number of Leguminosae in 
which the leaves’ disarticulate 
from a much elongated and di- 
lated base which persists on the 
stem. Usually such _ persistent 
leaf-bases are crowned by persist- 
ent stipules. In Calophaca these are exceptionally large. Its 
winter-buds are sheathed in similar notched leaf-bases so that 
they resemble those of hybrid barberry,— x Mahoberberis. 
The winter-characters of C. wolgarica are pictured by Schnei- 
der, f. 73. 
Stipules long (10 mm.): loosely hairy. c. grandiflora. 
Stipules. shorter (scarcely 6 mm.): puberulent. 
(1). C. wolgarica.
