198 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. 8S. National Herbarium, no. 679405, collected in the forests 
around Puerto Obaldfia, San Blas Coast, Panama, altitude 50 meters or. less, 
August, 1911, by H. Pittier (no. 4292). 
Of the subgenus Luleiphaimos, but not closely related to any of the described 
species. The blue corolla and long filaments enable one to distinguish it readily. 
4, Leiphaimos albus Standl., sp. nov. 
Whole plant white; stems slender, erect, sometimes decumbent at the base, 
6 to 14 cm. high, succulent, terete, glabrous, simple up to the inflorescence, or 
rarely with a short erect branch; cauline scales 4 or 5 pairs, 2 to 4 mm. long, 
‘distinct almost to the base, lanceolate, long-acuminate; inflorescence a several 
or many-flowered terminal flat-topped corymb, 1.2 to 3 cm. broad, 1.5 to 3 cm. 
high, the flowers all sessile or the terminal one short-pediceled; bracts usually 
present at the base of each branch and commonly 2 at the base of the calyx, 
small, thin, lanceolate, acuminate; calyx 3 to 4 mm. long, cleft halfway to the 
base, the tube campanulate, the lobes linear-subulate, the sinuses obtuse ; corolla 
tube slender, cylindric, dilated in the throat, 10 mm, long, about 1 mm. thick ; co- 
rolla lobes 5, ascending or spreading, trianguar-lanceolate, 2 to 2.5 mm. long, 
‘acute or acuminate; anthers subsessile, oblong, 1.25 mm. long, deeply bilobate, 
‘each lobe prolonged at the base into a short subulate appendage; style slender, 
3 mm. long; stigma capitate, 0.75 mm. in diameter, yellowish, tuberculate on 
the upper surface; ovary 6 mm. long, linear-lanceolate in outline, gradually 
tapering upward. 
Type in the U. S. National Herbarium, no. 679408, collected in forests around 
Puerto Obaldia, San Blas Coast, Panama, altitude 50 meters or less, August, 
1911, by H. Pittier (no. 4295). 
ADDITIONAL SPECIMEN EXAMINED! 
PANAMA: In forests, Loma de la Gloria, near Faté (Nombre de Dios), 
Province of Colén, alt. 10 to 100 meters, August, 1911, Pittier 4094. 
This is undoubtedly a member of the subgenus Leianthostemon. That group 
has been described as having long filaments, but the discovery of this plant 
* necessitates a modification of its characterization in this respect. Leiphaimos 
albus is related to L. corymbosus (Splitg.) Gilg, a species with a lilae corolla 
and long anthers. 
5. Leiphaimos thalesioides Standl., sp. nov. 
Stems fastigiately branched at the base, the branches simple up to the inflo- 
rescence or with one or two erect branches, purplish yellow, terete, succulent, 
glabrous; cauline scales usually 3 pairs, distant, thin, distinct nearly to the 
base or sometimes united for half their length, lanceolate or lance-ovate, 
acuminate to a subulate apex, glabrous; inflorescence a congested terminal 
corymb, composed of about 6 flowers, or the corymb sometimes fastigiately 
branched ; pedicels stout, 2 to 4 mm. long, subtended at the base by bracts 
similar to those of the stems; calyx 5 mm. long, ebracteate, cleft halfway to 
the base, the tube campanulate, 2 to 2.5 mm. in diameter, the lobes linear- 
lanceolate, long-acuminate, glabrous; corolla yellow, the tube 13 to 16 mm. long, 
slender-cylindric, 1 to 1.5 mm. in diameter, dilated in the throat; corolla lobes 
4 mm. long, oblong, acute or abruptly acute, more or less puberulent; anthers 
subsessile, oblong, appendaged at the base; style 6 mm. long, rather stout, 
glabrous; stigma capitate, 1 mm. in diameter, coarsely tuberculate on the 
upper surface; capsule narrowly oblong, sessile, acute, 5 to 7 mm. long. 
Type in the U. S. National Herbarium, no. 679499, collected on the hills of 
Sperdi, near Puerto Obaldfa, San Blas Coast, Panama, altitude 20 to 200 meters, 
September, 1911, by H. Pittier (no. 4351).
