that of The Now York Botanical Garden. One or more of the 

 coHections made by the author in 1886 and 1887 were referred 

 by Dr. Britton to F. salicifolia Presl, which, in the flowering 

 state, they very closely resembled. Later collections, made by 

 M. Bang and others, very closely resembled the former. Not 

 being well enough acquainted Avith the genus to know its ten- 

 dency to variation within the species, F. salicifolia was regarded 

 as a variable species, with many varieties or forms. A careful 

 study of the material that has now accumulated under this name 

 shows clearly that this view was erroneous, and that we have a 

 group of si^ecies closely resembling one another, not one of them 

 apparently representing the species to which they have been 

 referred. F. salicifolia is a species of southern Brazil, and prob- 

 ably does not occur in Bolivia, being distinguished from all 

 Bolivian species that I have seen by its strongly muricate fruit. 

 The folloAving species are proposed : 



Faramea benensis 



Glabrous. Branches obscurely quadrangular, the leaves di- 

 varicate. Stipules coherent into a ribbed cylinder 2 or 3 mm. 

 long, bearing four setae nearly as long as the sheath. Petioles 

 5 to 8 mm. long, margined, the margins more or less incurved. 

 Blades to 15 cm. long and 6 cm. broad, lanceolate, with the ab- 

 rupt base slightly produced into the petiole and the summit acu- 

 minate and acute; entire, thin but rigid, bright-green, the mid- 

 rib lightly prominent on both sides, the slender secondaries 8 or 

 10 on each side, diverging at a right angle but the outer portions 

 strongly falcate-ascending and looped together at some distance 

 from the margin, the venation inconspicuous. Cymes termi- 

 nating the upper branchlets, compound, loosely flowered, pe- 

 duncled, the peduncles or their branches angled. Pedicels 5 to 

 8 mm. long, slender, sharply angled. Calyx-tube 0.5 mm. long, 

 cupulate, the limb rotate, about twice as broad as the tube, 

 lightly 4-lobed. Corolla-tube 6 mm. long, the lower half nar- 

 rower and its middle portion somew^hat contracted, the lobes 4, 

 half as long as the tube, of thick texture, oblanceolate, obtuse, 

 the summit apparently bearing a black gland upon the inner 

 face. Anthers reaching the base of the corolla-lobes, half as long 

 as the tube, oblong, attached just above the base to a very slen- 

 der short filament. Style filiform, longer than the corolla-tube, 

 the style-branches short, slightly enlarged at the summit, obtuse. 

 Epigynous disk large, tumid, blackish.
