64 CONTRIBUTIONS FROM THE NAVIONAL HERBARIUM. 
Abutilon pedunculare. PICHANA PEDUNCULAR. 
Not found by Stahl on the north side of the island: neported by Bello from the 
south side. 
Abutilon periplocifolium. See Wissadula rostrata. 
Abutilon umbellatum. MatLvavisco CIMARRON. 
From the vicinity of Coamo (Sintenis). The common name was heard at Santurce. 
Acacia amarilla. See Albizzia lebbek. 
Acacia angustiloba. 
A leguminous plant, reported from Porto Rico by Bello, with the common 
name *‘cojobilla.”’ but Stahl thinks the seu saceer ee erroneous. and would refer 
Bello’s plant to Piptadenia peregrina. 
Acacia arabica. GUM ARABIC TREE. 
A native of the drier districts of Egypt, the Soudan, and East Africa. Culti- 
vated in Jamaica and other islands of the West Indies and, according to Grise- 
bach, naturalized in Antigua. It might be worth while to plant this species in 
the dry southwestern part of Porto Rico. 
Acacia berteriana. ACACIA SILVESTRE. 
According to Stahl, a small tree of 3 to 5 meters, preferring the summits of 
hil’s and shady situations. According to Grisebach, this species is abundant in 
some localities in Jamaica. Bello gives the common name ‘*cojoba”’ for this 
species. (Stahl, 3: 150.) 
Acacia farnesiana. ARoMo. 
A small tree introduced from the Old World; cultivated and now growing 
spontaneously in many parts of the West Indies. including Porto Rico. In the 
Mediterranean region it is extensively grown for the fragrant flowers. which are 
used in the manufacture of perfumery. 
The wood is very heavy and solid, reddish-brown in color, and very handsomely 
grained. It is nearly all heart and has a specific gravity of 1.117. This wood can 
be used to good advantage wherever strength and durability are required. It 
would appear that it would also be suitable for furniture. (Grosourdy, 2: 362.) 
Acacia lebbek. See Albizzia lebbek. 
Acacia nudifiora. AcAcrIa NUDOSA 
Stahl considers the occurrence of this species in Porto Rico doubtful, but it is 
known from St. Thomas and the neighboring Virgin Islands; also from Haiti. 
(Stahl, 3: 147.) 
Acacia nudosa. See Acacia nudifiora. 
Acacia palida. See Leucaena glauca. 
Acacia puertoriquena. See Calliandra portoricensis. 




Acacia sarmentosa. ACACIA ZARZA. 
A climbing. spiny shrub. widely distributed in the West Indies and South 
America. By some considered synonymous with A. riparia. (Stahl, 3: 148.) 
Acacia sylvestre. See Acacia berteriana. 
Acacia zarza. See Acacia sarmentosa. 
Acajou. See Guarea swartzii: also Swietenia mahagoni. 
Acaju. See Anacardium occidentale. 
This and the preceding are different spellings of the same word, evidently of 
French origin. in which language it is more properly applied to Swietenia mahog-. 
oni, but is also used with Anacardium occidentale and Cedrela glaziovii. 
Acalypha bisetosa. 
Family Euphorbiaceae; found by Sintenis, growing wild in the mountains near 
Yabucoa. Other species are cultivated as ornamentals.
