 much-branched, the branches sub-erect, rather slender for the 

 genus, sparsely leafy, the leaves falling readily : leaves sessile, 

 about 1.5 cm. long, 3-5 mm. broad, oblanceolate, broadest near

 nearly as broad as the leaves, 2— 3 -jointed, the joints gradually and 

 regularly broadening upward to about twice the width of the basal 

 portion : bracts (the pair) about 3.5 mm. broad, the upper margin 

 about horizontal, each equilaterally triangular in lateral outline, 

 acute : flowers moderately numerous, mostly above the middle of 

 the joint, moderately imbedded : perianth-segments triangular 

 ovate, obtuse, nearly 1 mm. long and broad. 



Sorata, 8000 ft., Feb., 1886 (no. 1537).

Plant drying of a deep yellow color: stems 1-1.5 dm. long,

 petioles 2 mm. long, 1 mm. broad, strongly concave on the upper 

 surface : blades 3 or 4 mm. long, 4 or 5 mm. broad, ovate, the 

 outline rounded : spikes 3-5 mm. long, 1—5 -flowered, short-pedun- 

 cled, the lower bracts small, the upper semi-circular, connate : 

 sepals nearly blood red in color, about 1 mm. long and rather 

 broader: pistil globoidal, less than .25 mm. in diameter: stami- 

 nate flowers not seen.

by Bang without number. 



Phoradendron Rusbyi Britton, sp. nov. 



Glabrous, the leaves finely papillose : stems stoutish but 

 weak, terete, irregularly branched, the -branches elongated : 

 petioles about 1 cm. long, very stout: blades .75-1.25 dm. long, 

 4-7 cm. broad, inaequilaterally ovate, rather abruptly narrowed 

 into the petiole, acuminate, the actual apex not present in the
