258 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Trichilia simplicifolia. CABo DE HACHA. 
(Stahl, 2: 166, as Photacilia diversifolia. ) 
Trichilia spondiodes. GUARAGUAO. 
A large dense tree 60 feet (18 meters) high with a long, straight trunk 6 to 64 
inches (15 to 16 centimeters) in diameter. It furnishes a wood that is neither 
very heavy nor very hard. This wood is much appreciated and was used by the 
military authorities of San Juan in the construction of heavy carts and for similar 
works; it is also made into boards, canoes, boats, and farm implements. (@Gro- 
sourdy, 2: 368.) 
Trichilia triacantha. 
A recently described tree of 5 to 10 meters, known from limestone mountains 
about Penuelas and Guanica. (Urban. Symb. 1: 329.) 3 
This species has most peculiar cuneate leaves, with the midribs and lateral 
corners produced into long, sharp spines. The texture and congested subdigitate 
arrangement of the leaves are also entirely different from that of the species of 
Trichilia and leave no doubt that Urban’s new section Acanthotrichilia should be 
looked upon as a new generic type peculiar to Porto Rico. The present species 
would probably make in cultivation a neat, handsome shrub. It is evidently 
adapted to a dry climate.
