MEMOIRS OF THE KKW YORK BOTANICAL GARDEN 



Lundia truncata 



Inflorescence, petioles, and veins of the lower leaf-surfaces 

 piiberulent. Branchlets terete, ^2,-ray-brown, finely costate. Leaf- 

 lets 2, snbe([nal. Petioles to 3 or 4 cm. lon^, slender, terete. 

 Petiolules about a third as long, slender. Blades to 8 cm. long, 

 5 cm. wide, ovate with truncate, mostly oblique base and very 

 abruptly acuminate and acute summit, very thin, bright-green 

 above, brown beneath, where the slender venation is moderately 

 prominent; 3- to 5-nerved from the summit of the petiole, the 

 nerves short, the secondaries 3 or 4 on a side, widely spreading, 

 the ends sharply up-curved, sparsely connected by crooked terti- 

 aries. Panicles axillary and terminal, mostly small and few- 

 flowered, the peduncles a little longer than the petioles, the 

 bracts and bractlets nearly obsolete. Pedicels 3 to 5 mm. long, 

 slender. Unopened buds shortly mucronate, the mucro mostly 

 expanded into the minute teeth. Calyx regularly turbinate, with 

 truncate summit, 6 mm. long and 5 mm. broad, ferruginous. 

 Corolla-tube broad, exceeding the calyx, the expanded portion 

 campanulate, nearly 2 cm. long, somewhat ventricose. Stamens 

 unequal, the 2 longer about as long as the corolla-tube, the others 

 about 5 mm. shorter. Connective not mucronate. Style exceed- 

 ing the stamens, the stigmas ovate, thin, whitish, connate at the 

 base to form a small concavity. 



Rurrenabaque, 1,000 feet, M. Cardenas, January 24, 1922 (no. 

 2036). Species very near L. phaseolifolia Rusby. 



Macfadyena violacea 



(The specimen is unique and consists only of the end of a 

 branch, bearing a pair of very young leaves and a terminal cyme 

 of eight flowers and buds.) 



Glabrous, with the exception of the inflorescence and a sparse 

 puberulence on the veins of the lower leaf-surfaces. Branchlets 

 very slender, herbaceous, costate or sulcate. Leaflets two, with 

 a tendril between. Petioles 3 cm. long, very slender, like the 

 petiolules, which are nearly 2 cm. long. Blades 8X3 cm., lan- 

 ceolate, obtuse at both ends, thin and herbaceous, the secondaries 

 8 or 10 on each side, strongly ascending and lightly curved, the 

 venation slender and obscure. Peduncle about as long as the 

 petioles, dichotomous, the branches slender, minutely subulate- 

 bracted. Pedicels about 1 cm. long, slender, sharply angled, 

 bearing a pair of early deciduous bracts near the calyx, which 

 are subulate and subscarious. Calyx cupulate-campanulate, 5 

 mm. long and wide, five-angled, the summit shortly, broadly.
