H. H. Rusby 



Rubus pendulus sp. now Caules robustissimi, ramis scan- 

 dentibus, ramulis pendentibus; folia trifoliata dense tomentosa; 

 petioli et venae primariae armatae aculeis brevibus recurvis 

 pungentibus; foliola late ovata subcordata obtusa serrato- 

 dentata, supra viridia scabrescentia venis venulisque anguste 

 impressis, subtus fulvo-tomentosa, venis venulisque valde promi- 

 nentibus; panicula fructifera gigantea pendula dense composita; 

 fructus magni ovatorotundati, calycis persistentis sepalis coria- 

 ceis concavis ovalibus acutis; drupellae confertae rotundatae 

 lucidae. 



Stems and branches very stout, climbing among the lower 

 branches of trees, some of the branches long-pendulous. Branch- 

 lets and petioles fleshy, very stout and, like the herbage, densely 

 ferruginous-tomentose. Petiole and lower surface of midrib 

 prickly, the prickles small, short and stout, little compressed, 

 strongly hooked and acute, with light-colored tips. Stipules and 

 flowers not seen. The two leaves collected are typical. Petioles 

 9 cm. long, 6 mm. thick at the base, nearly terete. Lateral peti- 

 olules about 1 cm., the terminal 4 cm. long, stout. Leaflets 3, 

 all alike or the terminal slightly longer, broadly ovate, lightly 

 cordate, obtuse or obtusish, about 10 by 8 cm., finely serrate- 

 dentate, the stout veinlets extending into the teeth. Leaf thick 

 but not rigid, dark-green and scabrescent above, where all the 

 veins are sharply impressed; beneath yellowish-brown and 

 softly tomentose, the venation very stout and prominent, the 

 secondaries about 12 on each side, nearly straight, at an angle 

 of about 45 degrees with the midrib, connected by numerous 

 straightish tertiaries. Fruit panicles very large and dense, pend- 

 ulous, Fruits black, densely crowded, nearly sessile, broadly 

 oval to sub-globular, about 2.5 cm. long, the drupelets compact, 

 about 4 mm. broad, with broadly rounded summit, glabrous and 

 shining. Pulp sour and bitter. Sepals 4 or 5 mm. long and equally 

 broad, ovate, concave, rigid, apiculate. 



Collected by Rusby and Pennell, at Balsillas, Colombia, 

 2000 to 2100 M., where it is known as "Mora India," and re- 

 garded as scarcely edible. 



Specimens deposited in the Economic Museum of the New
