MELASTOMIACEAE 15

Woodlands near Bayamon, in the Yabucoa Mountains and on Mt. Piedra Azul at
JAcana:-Hispaniola; St. Vincent.

Clidemia umbrosa (Sw.) Cogn. was recorded by Cogniaux as found at
Mayaguez by Krug, after a study of a leaf only, noting that the determination was
uncertain. Nothing more is known about the species in Porto Rico; it ranges
from St. Kitts to St. Lucia.

Clidemia spicata DC., recorded by Cogniaux as collected on St. Thomas
by Finlay, was really from Trinidad. Eggers erroneously records it as found on
all three of the former Danish Islands.

Clidemia rubra Mart., attributed by Naudin to St. Thomas as collected
by Finlay, was really from Trinidad.

Clidemia attenuata (Naud.) Cogn., recorded by authors as from St.
Thomas, collected by Finlay, was also from Trinidad. [Sagraea attenuata Naud.]

Hillsides and forests in moist districts, Porto Rico, at lower and middle elevations;
Vieques; St. Croix (according to Eggers); St. Jan; Tortola:-Cuba; Hispaniola; St. Martin
to Trinidad and northern South America. The leaves and twigs yield by distillation the
important oil of bay or bay oil; a superior kind of this oil is produced on St. Jan, where
there are extensive forests of the tree, obtained for the most part by clearing away other
trees and bushes thus permitting the bay trees to grow from seedlings without much
cultivation. Much oil is also obtained from wild trees In Porto Rico, but little or none
in St. Croix, St. Thomas or Tortola. The species consists of many races differing mainly
in the amount and quality of the oil contained, but also in shape, size and color of the
leaves and shape of the fruit. Reference is made to an important paper on "The Bay
Rum and Bay Oil Industries of St. Thomas and St. Jan" written by Mr. W. C. Fishlock
and published in West Indian Bulletin, Vol. 12, No. 4. The dark wood is strong, very
hard, tough, mottled and durable, with a specific gravity of about 0.9; it is utilized for
rollers, sills, posts and to some extent in carpentry. MALAGUETA. AUSU. GUAYAVITA.

A specimen of Rauwolfia canescens L., preserved in the Torrey Herbarium, is an-
notated as collected in St. Thomas by Perrin, without date, but doubtless many years
ago; as the species Is not otherwise known from Porto Rico or the Virgin Islands, the
record is believed to be erroneous. It differs from R. Lamarckii by densely tomentulose
leaves and obtuse calyx-lobes.

American species.

Echites thomasiana DC. is unpublished, appearing in Krebs' list of plants
found in St. Thomas, and not identified.
