SANTALACEAE. 43 
BUCKLEYA. 
(Family Santalaceae). 
Shrubs, parasitic on Tsuga: 
deciduous. Twigs slender, fork- 
ing, terete or obscurely 6-sided: 
pith rather small, somewhat angu- 
lar, continuous, white. Buds soli- 
tary, moderate, sessile, oblong, ap- 
pressed, with some 3 pairs of 
acute loose scales, the end-bud 
lacking. Leaf-scars opposite but 
by torsion standing nearly in 2- 
ranks instead of decussately in 4 
ranks, small, half-round or broadly 
crescent-shaped, slightly raised: 
bundle-trace 1: stipule-scars lack- 
ing. 
Buckleya affords one of the com- 
paratively few illustrations of 
successful garden cultivation of a 
parasitic plant of large size. Like 
its close relative Comandra, 
though possessing foliage abund- 
antly supplied with the mechanism for manufacturing carbo- 
hydrates through photosynthesis, as green plants ordinarily 
do, Buckleya appears to be incapable of existing without de- 
riving mineral nutrients and perhaps some proteins from 
other plants. In this respect it is partially comparable with 
the mistletoes—belonging to the closely related family Loran- 
thaceae, and other green parasites. It has long been grown 
successfully in the botanical garden of Harvard University 
under an old hemlock, to the roots of which it had attached 
itself. 
Puberulent: buds straw-colored, glabrous. B. distichophylla.
