longiuscule stipitatum, piloso-pubescens, in stylum tenuem exsertum  hispide 
pilosum excurrens, stylo incluso 5 em. longum. 
Camp VI o, 3100 ft. 
Leaves whitish-green when dry, slightly more so on the underside; petioles 4/5-5 em. 
long, pilose-villous. (One leaf, apparently not fully grown, is 5x 2:5 cm. and borne on 
a petiole only 2:5 mm. long.) Longer filaments 31 mm., shorter 28 mm. long. 
Greatly resembling D. concinnwm in indumentum and foliage, but unlike in calyx 
and corolla and in the hairy ovary and style. 
DICHROTRICHUM LATERITIUM, S. Moore, sp. nov. 
Caulis scandens, radicans, dense villosus. Folia dimorpha, majora ovata, sursum 
attenuata, apice obtusa, basi obliqua rotundata, margine crenato-serrata, pergamacea, 
utrinque ut petioli villoso-tomentosa, petiolis sese subeequantibus insidentia 6—7 X 
3:5-4 em.; folia minora valde imminuta. Cyme@ 9-flore; pedunculus validus, 
foliis brevior, villosus, 4'5 cm. longus; pedicelli breves, 4-5 mm. longi, ut calyx 
sparsim villosi. Calyx subcampanulatus, ad dimidium vel trientem inferiorem 
indivisus, 13-15 mm. longus; lobi oblongo-lanceolati, obtusi, 7:5-10 mm. longi. 
Corolla 4 em. longa, extus dense scabriuscula; tubus subrectus, a basi gradatim 
ampliatus, basi constrictus, 20 mm. longus, juxta medium 5 mm., faucibus 10 mm. 
latus; lobi postici 8 mm. longi. Antherarum loculi basi contigui. Ovarium 
stipitatum, ut stylus puberulum, 3 cm. longum ; stylus sat brevis, 8 mm. longus, 
ovario vix sequilatus. 
Camp Vie, 5500 ft. 
Leaves whitish-green ; petioles 5-5:5 cm. long. Long filaments 24 mm., short 20 mm. 
long; anthers 3-375 mm. long. 
This differs from the last two in the indumentum. It has the shorter and relatively 
broader corollas of D. concinnum and the calyx divided at least to the middle; but its 
peduncle is slender, the calyx-segments oblong-lanceolate, and the much thicker ovary 
and style are hairy, though less so and in a different manner from the same organs in 
D. Vanderwateri. The cutting of the leaf-margin is also different from that which 
obtains with D. concinnum and D. Vanderwateri. 
DICHROTRICHUM PARVIFOLIUM, S. Moore, sp. nov. ; 
Caulis scandens, radicans, bene foliosus, pilosus, tandem fere glaber. Folia dimorpha, 
majora ad normam generis parva, sat longipetiolata, ovata sæpius ovato-oblonga, 
obtusa, basi obliqua obtusa, margine argutiuscule serrata vel serrato-crenata, 
membranacea, utrinque ut pedunculi appresse piloso-villosula, circa 4x2 cm. ; 
folia minora diminuta. Pedunculus folia magnopere excedens, 14-15 cm. longus, 
aliquanto nutans, cymam 5-9-floram fulciens; pedicelli calyci æquilongi, ut calyx 
piloso-villosi. Calyx 13 mm. longus, subturbinatus, medium usque lobatus, lobis 
lanceolato-oblongis obtusis margine denticulatis. Corolla calyce fere ter longior, 
extus scabrida, 35 mm. longa; tubus subrectus, basi haud constrictus, inferne | 
tubulosus, inde sensim dilatatus, 24 mm. longus, inferne 3 mm., faucibus fere 8 mm.
