226 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Psychotria platyphylla. 
A new variety angustior is described from mountain stations near Adjuntas; 
found also as Utuado. (Urban, Symb. 1: 449.) 
Psychotria pubescens. 
A shrub 10 to 12 feet (3 to 4 meters) high, in mountain woods. Pefuelas, on 
Mount Llano. 
Psychotria sintenisii. 
A shrub from the vicinity of Cobo Rojo. (Urban, Symb. 1: 448.) 
Psychotria undata. Batsamo. . 
A specimen supposed to represent this species was obtained at Vega Baja (No. 
1019) under the name ‘‘ balsamo.”’ 
Pterocarpus draco. PALO DE POLLO. 
Family Viciaceae; a tree 20 meters high, found along swampy coasts. Wood 
soft. (Stahl, 3: 93.) 
Grosourdy contracts the native name to ** palo pollo,”’ and describes it as a wild 
tree, 40 feet (12 meters) high, with a trunk 14 to 18 inches (35 to 40 centimeters) 
in diameter, furnishing a wood dirty-white in color that breaks with a horizontal 
fracture. In San Juan fire screens are constructed of this wood. Also used as 
fuel. Specific gravity, 0.554. Of dry wood from the roots, 0.138. (Grosourdy, 2: 
407.) 
Pterocaulon virgatum. EscoBiLLon. 
An herbaceous, erect annual, composite, 50 ceutimeters high, growing in sandy 
pastures. (Stahl, 5: 124.) 
Punica granatum. POMEGRANATE. GRANADA. 
The pomegranate is a fruit adapted to dry climates, such as those of North 
. Africa, Arabia, and Persia. The north side of Porto Rico is probably too moist, 
but in the dry southwestern corner of the island more favorable conditions may 
be found, although extensive planting is not likely to be found advisable. The 
bush resembles slightly the Japan quince, and has showy red flowers. Little fruit 
was seen, and that was small and inferior. Southern California and Arizona can 
probably produce the pomegranate to much better advantage than Porto Rico, 
but there is little demand for it in the general market, and no indication that it 
will become popular outside the dry climates where other more satisfactory fruits 
are scarce. 
Propagation from cuttings is easy, and in South Africa excellent pomegranate 
hedges are said to be frequent. The bark and the rind of the fruit contain a yellow 
dye used for leather in Morocco. 
In the market of Ponce it was claimed that there were two forms, ** blanco’ and 
““colorado,’’ but the difference was very slight. 
Pursaetha. 
In Engler and Prantl’s Natiirlichen-Pflanzenfumilien the genus Entada is treated 
as a synonym of Pursaetha. 
Quamoclit coccinea. CAMBUTERA. 
An annual, cultivated in gardens. (Stahl, 6: 165.) 
Quamoclit quamoclit. CYPRESS VINE. CAMBUTERA. 
A climbing herbaceous annual, cultivated in gardens. It has a variety of names 
in Jamaica, viz, Indian creeper, Indian pink, red bell flower, Barbadoes sweet 
william. Bello writes the common name ‘‘cambustera.’’ (Stahl, 6: 164.) 
Quararibea turbinata. GARRACHO. 
Family Bombacaceae; a wild tree 5 meters high, common in all parts of the 
island. Bello records the name ‘‘palo de garrocha’’ for Myrodia turbinata. 
(Stahl, 2: 101.)
