 W. I.)- 

 Tree from 20 to 50 feet high and from 1 to 2 feet in diameter, introduced from the 

 East Indies and now largely naturalized throughout the island. The wood is used 

 for barrel hoops, poles, fuel, and charcoal. It also furnishes material from which 

 large baskets are made. 



"Wood grayish brown, fine and straight grained, hard, heavy, strong, and tough. 

 Pores small and arranged in irregular tangential lines. Pith rays very narrow and 

 scarcely visible under the hand lens. 



XLIII. Melastomatace^e. 



134. Miconia tetrandra (Sw.) D. Don. Camasey. 



Tree from 30 to 50 feet high and about a foot in diameter, common in the moun- 

 tains of Porto Rico and found on all the islands of the West Indies. The wood is used 

 for poles, fuel, and charcoal. - 



Wood light brown, fine and straight grained, hard, moderately heavy, strong, 

 flexible, and durable in the soil. Pores small, numerous, and evenly distributed. 

 Pith rays very narrow and inconspicuous. 



Note 1. — Three other species in this genus similar in size, distribution, and 

 uses are Miconia guianensis (Aubl.) Cogn. (Camasey, Camasey bianco, Camasey 

 de costilla); Miconia impetiolaris (Sw.) D. Don (Camasey, Camasey de costilla) 

 and Miconia prasina (Sw.) P. DC. (Camasey). 



Note 2. — Three other genera and six species in this family attain tree size, 

 though they are of but slight local or general importance, namely, Calycogonium 

 squamulosum Cogn. (Granadilla cimarrona), from 15 to 30 feet high, from the 

 Sierra de Luquillo; Calycogonium bifiorum Cogn., from 25 to 30 feet high, from 

 near Barranquitas; Heterotrichum cymosum (Wendl.) Urb. (Camasey Colorado, 

 Camasey de paloma, Terciopelo), from 25 to 30 feet high, from various parts of 

 the island; Henriettella macfadyenii (Triana), 60 feet high, from Sierra cle Luquillo 

 and Cordillera Central, found also in Jamaica; Henriettella membranifolia Cogn., 

 30 feet high, from Lares; and Henriettella fascicularis (Sw.) Ch. Wright (Camasey 

 de oro, Camasey de paloma), from 25 to 30 feet high, from various places on the

XLIV. ARALIACE.E. 



135. Gilibertia arborea (L.) E. March {—Aralia arborea L.). Muneca, Palo cachumba, 



Pana, Vibona. 



Tree from 30 to 60 [feet high, quite common throughout the island, and found in all 

 parts of the West Indies. The wood resembles boxwood (Buxus sempervirens L.) and 

 should make a suitable substitute. 



Wood light or pale yellow, very fine grained, taking a good polish, very hard, heavy, 

 strong, and tough. Pores very small, numerous, scarcely visible under the hand lens, 

 and evenly distributed. Pith rays very narrow and inconspicuous. 



Note. — Another species in every way similar to the above is Gilibertia lauri- 

 folia E. March (Palo cachumba, Palo de gangulin, Palo de vaca, Vibona). 



*136. Didymopanax morototoni (Aubl.) Dene et PI. Yagrume macho, Yagrume; 

 Grayume, Grayume macho, Grayumo, Pana cimarrona, Llagrume, Llagrume 

 macho. 



Tree from 40 to 60 feet high and about a foot in diameter, very common in the 

 mountains and distributed quite generally throughout tropical America. The wood 

 is used for boards and beams in house building, and has been suggested as a good 

 material for making matches. 



Wood light olive brown, fine and straight grained, moderately hard, heavy, brittle, 

 and not strong. Pores small, very numerous, and more or less evenly distributed 

 throughout the annual rings of growth, which can be readily distinguished by means 

 of the hand lens. Pith rays very conspicuous. »
