STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 197 
in diameter, slightly dilated above but somewhat contracted at the mouth; 
corolla lobes 5, spreading or ascending, oblong, obtuse, 7 mm. long; filaments 
stout, about 1 mm. long, inserted 3 mm. below the mouth of the corolla; anthers 
almost rotund in outline, deeply bilobate, exappendiculate ; style slender, 2.2 em. 
long; stigma capitate, 1.5 mm. broad, obscurely papillose on the upper surface, 
smooth beneath; ovary sessile, oblong in outline, rounded at the base, truncate

Type in the U. S. National Herbarium, no. 888489, collected on the high hills 
back of Puerto Obaldia, San Blas Coast, Panama, altitude 50 to 200 meters, 
August, 1911, by H. Pittier (no. 4306a). 
Of the subgenus Huleiphaimos Gilg and related to L. spathaceus and L. 
calycinus. Both these species have blue or lilac corollas with acute lobes and 
more foliaceous, less completely connate cauline bracts. Leiphaimos truncatus 
may be distinguished from all other species by the truncate ovary. The type 
material is fragmentary, but it is suflicient to show all the important characters. 
2. Leiphaimos stellatus Standl., sp. nov. 
Stems very slender, erect, 1-flowered, succulent, terete, pinkish, glabrous, 4 
to 12 cm. high; bracts opposite, 4 or 5 pairs, distant, oblong-linear or lance- 
oblong, 5 to 8 mm. long, with long-acuminate subulate tips, united for about 
half their length; peduncles slender, 11 to 23 mm. long; calyx pinkish or 
nearly colorless, ebracteate, 5 to 12 mm. long, 5-lobate to about the middle, the 
tube cylindric-campanulate, 1 to 2 mm, in diameter, the lobes linear-lanceolate, 
long-acuminate, with subulate tips; corolla bright orange-yellow, the tube 
slender, cylindric, 12 to 17 mm. long, slightly dilated in the throat, the lobes 
narrowly lanceolate to narrowly elliptic, 8 to 14 mm. long, 1.5 to 3 mm. wide, 
acuminate, rather conspicuously parallel-nerved, especially in old specimens, 
puberulent on the upper surface near the base, the pubescence extending to the 
throat of the tube; anthers subsessile, oblong, distinct, not appendaged; style 
slender, 6 to 8 mm. long, glabrous; stigma capitate, minutely tuberculate on the 
upper surface; ovary oblong, abruptly acute or acuminate, sessile; ovules ovoid. 
Type in the U. S. National Herbarium. no. 679407, collected in forests around 
Puerto Obaldfa, San Blas Coast, Panama, altitude 50 meters or less, August, 
1911, by H. Pittier (no, 4294). 
This belongs to Gilg’s subgenus Wuleiphaimos, and is closely related to L. 
tenuiflorus (Griseb.) Miquel. That species, however, has a short calyx, only 
one-fourth as long as the corolla tube, aud subulate cauline scales. 
3. Leiphaimos pittieri Standl., sp. nov. 
Stems very slender, 5 to 12 cm. high, erect, terete, glabrous, purplish, simple 
or once dichotomous above, the branches when present strictly erect; cauline 
bracts 4 or 5 pairs, distant, lanceolate or linear-lanceolate, acuminate to a 
subulate tip, 5 mm. long, erect or appressed, purplish, free nearly to the base; 
peduncles slender, 6 to 14 mm. long; calyx purple, ebracteate, cleft about half- 
way to the base, 5 mm. long, 1.5 mm. in diameter, the tube narrowly campanu- 
late, the lobes lanceolate or lance-linear, long-acuminate to a subulate tip; 
corolla lilac or pale blue, the tube very slender, 14 to 16 mm. long, slightly di- 
lated in the throat and there 3 to 4 mm. wide; corolla lobes narrowly oblong 
or oblong-lanceolate, acuminate or abruptly acuminate, 5 to 6 mm. long; an- 
thers narrowly oblong, 1 mm. long, not appendaged, on very slender, slightly 
puberulent filaments, these inserted about one-third the distance above the base 
of the tube; style slender, 12 mm. long, puberulent; stigma capitate, slightly 
tuberculate on the upper surface; ovary oblong or lance-oblong in outline, 2.5: 
min. long, obtuse, sessile; ovules ovoid, not appendaged.
