PINACEAE. 5 
TaxopiuM. Bald Cypress: 
(Family Pinaceae). 
Percurrent, somewhat shredding- 
barked trees, when large often 
buttressed, and in very wet places 
surrounded by large _ conical 
“knees” developed from the roots: 
deciduous. Twigs slender: pith 
minute, brown, roundish, rather 
spongy. Buds _ sessile, minute, 
subglobose, with few scales, com- 
monly indistinct and very fre- 
quently represented by round 
scars from which transient foliage- 
sprays of the season have fallen, 
solitary unless developing into 
flower-clusters. Leaf and stipule- 
sears lacking, the buds subtended 
by minute scales or their vestiges. 
Fruit, when persistent, in the form 
of small ellipsoid cones with 
thickened scales. 
The conical form of the bald 
cypress is very different in appearance from the open-topped 
tree of cypress swamps; but young trees about the borders 
of the swamps are usually of this form. The very high knees 
of old trees in some localities correspond to a former high- 
water level. An interesting account of the tree in its 
various forms, by Wilson, is to be found in the first volume 
of Biological Lectures of the Marine Biological Laboratory 
at Wood’s Hole. 
The Montezuma cypress of Mexico is evergreen through 
persistence of its foliage-shoots. 
With flat open top. T. distichum. 
Conical: the usual cultivated form. T.distichum pyramidatum.
