West India, and also on the continent of Central America.
The stem of this Fan-Palm attains a height of twenty-five
feet. I t belongs to the sand-tracts of the coast and may

ropes. T. argentea (Lodd.) is a closely allied palm. The
few other species of the genus deseiwe also trial-culture here.
Thuya gigantea, Nuttall.
North-West America, on the banks of the Columbia River.
The Yellow Cypress of the colonists. A straight, graceful
tree 200 feet high, furnishing a valuable building-timber of
a pale or light-yellow colour, known as the Oregon White
Cedar-wood, susceptible of high polish. The diameter of the
stem attains ten feet or even more. The timber is light.
Canoes carrying four tons have been obtained out of one
stem. The bast can be converted into ropes and mats.
Thuya occidentalis, Linné.
North America, particularly frequent in Canada. Northern
White Cedar. A fine tree, seventy feet high ; the wood is
reddish or yellowish, fine-grained, very tough and resinous,
and well fit for building, especially for water-work ; also for
turnery and machinery. Michaux mentions that posts of this
wood last forty years ; a house built of it was found perfectly
sound after sixty years. I t prefers moist soil. Yaluable for
hedge-copses ; it can also be trained into garden-bowers. The
shoots and also an essential oil of this tree are used in
medicine ; the bast can be converted into ropes. The
branches serve for brooms. .

Thymelæa tinctoria, Endlicher. {Passerina tinctoria, Pourr.)
Portugal, Spain, South France. A small shrub. I t yields a
yellow dye. Cursorily it may he noted here, th a t some of
our Pimeleæ contain a bine pigment, which has not yet been
fully tested. Tbeir bark produces more or less of Daphnin
and of tbe volatile acrid principle, for which the bark of
Daphne Mezereum (L.) is used. These are remarkably
developed in the Yictorian Pimelea stricta (Meissn). The
bark of many is also pervaded by a tough fibre, that of the
tall Pimelea clavata (Labill.), a West Australian bush, being
particularly tenacious, and used for whips.
