GLOSSARY. 183 
Dotted. As here used, referring to the presence of lighter or 
darker spots or of rather regularly and closely placed 
blackened hairs or glands, usually on the under side of 
a leaf. 
Double. With more than the normal number of petals, as 
applied to flowers. Double poinsettias have their bracts 
increased: double hydrangeas, their neutral flowers. 
Downy. Pubescent, with the hairs short, soft and spreading. 
Drooping. Hanging from the base so as to suggest wilting, 
like the leaves of peach and sweet cherry. 
Drupe. A “stone-fruit”, typically with the outer part succulent 
and one hard kernel (plum): but the flesh may be thin and 
dry (almond), or may contain several stones (holly). In a 
huckleberry the stones are small and seed-like, but their 
presence is shown by the crackling sound when they are 
broken between the teeth,—quite different from the be- 
haviour of a blueberry. 
Drupelet. A diminutive drupe. 
Ducts or vessels. The water-passages in wood: appearing as 
pores in cross-section. When larger or crowded in the 
spring-growth, they make the wood “ring-porous” (oak) ; 
when uniform in size and disposition, they render it “dif- 
fused-porous” (walnut). The smaller ducts are often 
arranged in flame-like radiating patterns (oak), or wavy 
tangential patterns (elm). 
Dull. Not glossy; not brightly colored. 
Ellipsoid. Shaped like a foot-ball, as applied to fruits, ete. 
End-bud. The characteristic growing tip of a stem or its branch: 
sometimes replaced by a flower (magnolia) or cluster of 
flowers (horse-chestnut) and then not found in winter; and 
sometime regularly cast off during the growing season 
(linden) or dying back before winter (willow). 
_Endogens. Inside-growing plants,—forming new wood, if at 
all, as new threads between the old (Smilax, palms etc.). 
Entire. With the margin neither toothed nor lobed, as applied 
to leaves and leaflets. |
