COOK AND COLLINS—-ECONOMIC PLANTS OF PORTO RICO. 93 
of food, but so little canse is there to fear its effects that when in season it is to be 
found generally on the tables of both rich and poor throughout Jamaica. The 
vases in which the fruit has produced poisonous effects are generally found to be 
such as show a careless preparation of the fruit for food. The arillus when in 
good condition is of a wholesome, nutty flavor, and should be quite firm and not 
easily broken. If, however, it is kept too long it readily becomes soft and decays, 
and such decayed parts are doubtless poisonous as any other decayed vegetable or 
animal matter and quite as likely to cause irritant poisoning, Care should there- 
fore be exercised by the housewife in preparing such a delicacy for table, and if 
such is taken it may be eaten without the slightest fear, and with the satisfaction 
of having partaken of one of the finest bonne bouches that come to a West Indian 
table. The writer speaks of it from experience of some twenty years, during 
which time he has missed no opportunity of securing a share of it when in 
season.” 
Blood flower. See Asclepias enrassavica., 
Bocagea laurifolia. 
Family Anonaceae; from Guajataca and Sierra de Lares. 
Bocconia frutescens. PALO DE PAN CIMARRON. 
Family Papaveraceae; an herb with a disagreeable odor. (Stahl, 2: 34.) 
Boehmeria cylindrica. 
An urticaceous plant of interest chiefly because related to the next species; 
known from Aybonito. 
Boehmeria nivea. RaMIr, 
Family Urticaceae; the now celebrated ramie plant or Chinese hemp, the culti- 
vation of which has been so widely advocated. Notwithstanding the numerous 
attempts at commercial utilization of the fine fiber produced by this species, prac- 
tical success has not yet been attained, the satisfactory processes and machinery 
for degumming the fiber being too complicated and expensive to permit ramie to 
compete in the manufacture of cheap fabrics. The Porto Rican specimens were 
found by Sintenis in cultivation, near Cabo Rojo. It is not known whether any 
local use has been made of the fiber. 
Boerhavia paniculata. TostTon. 
Family Nyctaginaceae; this species and B, hirsuta are common tropical weeds 
known from Porto Rico, but without recorded local names, ** toston “* being given 
as Cuban only. (Urban, 3: 307, 308.)
