7. TRIITMFETTA T^. Sp. PI. 444. 1753. 



Shrubs or sometimes herbs, with stellate pubescence; leaves often 3 or 5- 

 lobate ; flowers small or large, yellow, axillary or opposite the leaves, fasciculate- 

 cymulose; sepals 5, appendaged at apex; petals 5, rarely absent; stamens 10 

 to many; fruit subglobose, 2 to 5-celled, indehiscent or separating into 2 to 

 5 cocci, covered with short or long spines, each of these uncinate at apex. 



The fruits adhere readily to cothing and other objects by their hooked 

 spines. The inner bark of all species yields a strong fiber, resembling jute, 

 which is suitable for the manufacture of cordage. 



The plants are said to have received the name " paroquet-bur " in Jamaica, 

 because parokets feed on the ripe fruit. The names " jonote," " cajete " 

 (Chiapas), and " giiizapol de borrego " (Jalisco) are reported for Mexican 

 plants of the genus, whose specific identity is uncertain.
