XXVI. Sapindaceje. 



94. Thouinia striata Radlk. Ceboruquillo, Guara, Quiebra hacha, Seburoquillo. 



Tree from 25 to 65 feet high, occurring generally throughout the island, usually in 

 the drier situation s. No uses are reported for the wood , doubtless because of its extreme 

 hardness. 



Wood light-colored, very fine-grained, with many fine light lines, giving a pleasing

 minute, isolated, or in groups of two or three, evenly distributed. Pith rays minute, 

 inconspicuous.

 A cultivated and semiwild tree from 25 to 60 feet high and up to 3 feet in diameter 



reported from the east, south, and west parts of the island. It is native of tropical 

 America and is found throughout the West Indies. It is cultivated somewhat for its 

 fruit and is also suitable for ornament and for roadside shade. Wood is said to be 

 heavy and hard and useful for all purposes except in exposed situations. No local 

 uses are reported. 



*96. Cupania. 



There are two species of this genera represented in the tree flora of Porto Rico, 

 namely, Cupania americana L. (Guara, Guara blanca), and Cupania triquetra A. Rich. 

 (Guara). 



Trees from 30 to 60 feet high, quite widely distributed locally, and occurring gener- 

 ally throughout the West Indies. The woods of all are alike and are used largely for 

 posts.

 soft, moderately light, and brittle. Pores solitary or in groups of two or three, evenly 

 distributed. Pith rays minute, very inconspicuous.

Wood red, fine and straight grained, taking a beautiful polish and resembling dark- 

 colored mahogany. It is hard, heavy, strong, tough, and very durable. Pores rather 

 large, solitary, and evenly distributed; pith rays are narrow and more or less indistinct 

 except under the hand lens. 



Note. — Another species Matayaba apetala (Macf.) Radlk. (Doncella) is also 

 reported from the same localities. Size and uses are not noted, although in 

 Jamaica it is reported as attaining a height of from 40 to 60 feet and a diameter of 

 2 J feet and as being a most useful hardwood, suitable for all purposes and especially 

 for exposed situations.
