132 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Cynara scolymus. ARTICHOKE. ALCACHOFA. 
A few specimens of the genuine European artichoke were seen near Santurce, 
apparently escaped from cultivation. 
Cynodon dactylon. See Capriola dactylon. 
Cynometra portoricensis. 
Family Cassiaceae; a leguminous tree, 15 meters in height, recently described 
from the vicinity of Rincon. (Urban, Symb. 1: 312.) 
Cyphomandra betacea. TREE TOMATO. 
A plant related to the tomato and at first placed in the genus Solanum. It 
grows rapidly to a height of 10 or 12 feet (3 to 4 meters), becoming a veritable 
shrub or small tree. The heart-shaped flowers are sometimes a foot in length. 
The fruits are borne in clusters, and are oval in shape, or somewhat pointed; the 
color is purplish or reddish, and the taste is similar to that of the ordinary tomato, 
though some have reported a gooseberry flavor in the ripe, raw fruit, and if 
stewed after the skin and seeds have been removed a resemblance to apricot is 
said to be developed. It has become very popular for tarts and pastries; also 
for jellies and preserves. The suggestion which is considered under the eggplant 
of grafting on Solanwm mammosum might also find application in the present 
instance. 
Cyphomandra is a native of the Andes of Peru and neighboring regions of trop- 
ical America, but has been successfully introduced into Jamaica, Ceylon, and 
other mountainous regions of the Tropics, and at many places is considered a valu- 
able addition to the list of garden vegetables. It would in all probability thrive 
in Porto Rico, and as it can be propagated readily from seed its introduction 
offers no special difficulties. 
Cypress vine. See Quamoclit quamoclit. 
Cyrilla antillana. Crema. 
Family Cyrillaceae; a tree found on the south coast. From the vicinity of 
Utuado and at Santa Ysabel. (Stahl, 6: 34.) 
Dacryodes excelsa. 
A tree of the family Burseraceae; reported from near Maricao. 
Dacryodes hexandra. Tasonuco. PLATE XXXIV. 
A tree exuding a resin used for torches; found in mountain districts. Grise- 
bach gives it as 10 to 15 feet high; Stahl as 75 feet high. The trunks are used for 
lumber. (Stahl, 4:53.) 
Near Isolina there still exists a considerable area of virgin forest composed 
largely of what was taken to be this species. The trees are much higher than 
even the figures given by Stahl, with very smooth, straight, white trunks, often 
scarred near the base where they have been cut to secure the resin. The wood 
has a beautiful color and is said to be free from the attacks of insects. 
Dalbergia ecastaphyllum. Maray-MARAy. 
A leguminous shrub, 3 to 4 meters high, found in thickets along the coast. 
Dalbergia monetaria. PALO DE BRASILETE. 
The red wood is said to furnish a resin resembling dragon’s blood. Known from 
Utuado as Hecastaphyllum monetaria. (Stahl, 3: 97.) 
Dalechampia scandens. 
Family Euphorbiaceae; a twining shrub: from Guanica. 
Dama de noche. See Cestrum nocturnum and Murraya exotica. 
Dama juana. 
Captain Hansard gives the specific gravity of 0.82 for the wood of this species. 
Daphnopsis caribaea. 
Family Thymelaeaceae; a tree 20 to 30 feet (6 to 9 meters) high; known from 
Cayey.
