STANDLEY TREES AND SHRUBS OE MEXICO. 1041 



1. Eugenia jambos L. Sp. PI. 470. 1753. 

 Jambosa vulgaris DC. Prodr. 3: 286. 1828. 

 Jambosa jambos Millsp. Field Mus. Bot. 2: 80. 1900. 



Cultivated in Guerrero, Veracruz, Tabasco, and doubtless elsewbere ; prob- 

 ably naturalized locally. Native of southeastern Asia and Australia, but wide- 

 ly cultivated and naturalized in tropical regions. 



Glabrous tree, 6 to 9 meters high ; leaves short-petiolate, narrowly lanceolate, 

 12 to 20 era. long, long-attenuate, coriaceous ; flowers greenish white, sweet- 

 scented, in few-flowered terminal cymes, the petals 1.5 to 2 cm. long; stamens 

 very numerous, 3 to 4 cm. long ; fruit pyriform or subglobose, 3 to 5 cm. thick, 

 white or yellowish, tinged with pink. " Pomarosa " (Veracruz, Oaxaca. El 

 Salvador, Guerrero, Porto Rico); " manzana rosa " (El Salvador). 



The rose-apple is cultivated for its fruit, which is fragrant like roses. The 

 fruit is sweet and insipid ; it is used locally for making preserves and con- 

 fectionery. In some parts of the American tropics the tree has become thor- 

 oughly naturalized. In Porto Rico the branches are employed for hoops of 

 sugar casks and for coarse baskets. The pulverized seeds are employed in 

 El Salvador as a remedy for diabetes, and the wood is used for fuel. The 

 tree is a handsome one for ornamental planting. 



2. Eugenia trunciflora (Schlecht. & Cham.) Berg, Linnaea 27: 223. 1854. 

 Myrtus trunciflora Schlecht. & Cham. Linnaea 5: 561. 1830. 



Veracruz; type material collected between Mesa Chica and Malpique, and 

 at Papantla. El Salvador. 



Branchlets pilose or glabrate ; leaves short-petiolate, elliptic-oblong, 12 to 

 25 cm. long, 4 to 10 cm. wide, acuminate, coriaceous, minutely pilosulous be- 

 neath or glabrate, lustrous above; pedicels fasciculate on the old branches, 

 the pedicels 8 to 15 mm. long; calyx about 1 cm. wide, the lobes rounded, 

 ciliate. " Icaco " (El Salvador). 



The writer has referred here two specimens from Zacuapan, Veracruz 

 {Purpus 2434 and 7663). These differ from the original description in hav- 

 ing pubescent leaves, and they may be specifically distinct. 



3. Eugenia conzattii Standi., sp. nov. 



San Luis Potosl, Veracruz, Oaxaca, and Guerrero; type from Apango, Dis- 

 trito de Pochutla, Oaxaca, altitude 400 meters (Conzatti, Reko d Makrinius 

 3113; U. S. Nat. Herb. no. 763841). 



Shrub or small tree, glabrous throughout; leaves short-petiolate, lanceolate 

 to oblong-lanceolate or elliptic, 5 to 8.5 cm. long, 1 to 4 cm. wide, abruptly 

 acuminate or long-acuminate, with acute or obtuse tip, acute or obtuse at 

 base, thin; pedicels sometimes fasciculate but most of the flowei*s in long- 

 pedunculate 3-flowered cymes, the central flower usually sessile, the lateral 

 ones filiform-pedicellate; calyx about 3 mm. broad, the lobes rounded, ciliate; 

 fruit globose, 6 to 8 mm. long, 1-seeded. " Yagaian " (Oaxaca, Reko). 



Galeotti 2882 and 2887 from Oaxaca belong here, also Palmer 148 from 

 San Luis Potosi, and probably Rovirosa 510 from Tabasco. The specimens 

 from eastern Mexico have wider leaves than those from Guerrero and Oaxaca, 

 but probably all are conspecific. Upon the same plant some of the flowers 

 are solitary and others cymose. The fruit is said to be edible. 



4. Eugenia fragrans (Swartz) Willd. Sp. PI. 2: 964. 1800. 

 Myrtm fragrans Swartz, Prodr. Veg. Ind. Occ. 79. 1788.

Tepic, Durango, San Luis Potosi, Tamaulipas, and Veracruz. "West Indies. 



Shrub or tree; leaves elliptic-oblong to obovate or elliptic, 2.5 to 7 cm. 



long, 1.5 to 4 cm. wide, obtuse to rounded at apex, sometimes acutish or emargi-
