STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 199 
This, like L. albus, is a somewhat anomalous representative of the subgenus 
Leianthostemon, differing from the described species of that group in its sub- 
sessile anthers. It is not very closely related to any of them in its other 
characters. 
6. Leiphaimos pulcherrimus Standl., sp. nov. ; 
Stems slender, simple below, sparsely fastigiate-branched above, erect, 8 to 
18 cm. high, the branches erect, terete, purplish; scales of the stem oppo- 
site, the pairs 8 to 17 mm. apart, rather thick, broadly oblong or oblong-oval, 
rounded or obtuse at the apex and ciliolate, united for about half their length; 
peduncles slender, 13 to 22 mm. long; calyx ebracteate, purplish, narrowly 
campanulate, 5 to 6 mm. long, 2.5 to 3 mm. in diameter, the 5 teeth broadly 
ovate or semi-orbicular, rounded at the apex, ciliolate, about 1 mm. long; 
corolla bright yellow, the tube 2.1 to 2.6 cm. long, gradually dilated from 
above the base to the mouth, about 2 mm. in diameter at the base and 5 to 7 
mm. at the mouth, minutely papillose within, the lobes 5, oval or oval-oblong, 
rounded at the apex and minutely puberulent, about 9 mm. long and 5 to 6 mm. 
wide, spreading, papillose at the base; filaments slender, inserted about 1 cm. 
above the base of the corolla, about 15 mm. long, minutely retrorse-pilose ; 
anthers narrowly oblong, 2 mm. long, with short slender appendages at the 
base, coherent; pollen grains ovoid; style slender, 16 mm. long, glabrous; 
stigma capitate, short-conic, 1.5 mm. broad, nearly smooth on the upper surface ; 
ovary sessile, narrowly oblong. 6 to 7 mm. long, obtuse at the apex. 
Type in the U. S. National Herbarium, no. 679480, collected on the high 
hills back of Puerto Obaldia, San Blas Coast, Panama, altitude 50 to 200 
meters, August, 1911, by H. Pittier (no. 4806). 
This doubtless belongs to the subgenus Leianthostemon, of which four species 
are known. It has little to do with any of the described species of this group, 
however, differing from all of them in its fastigiately branched stems, obtuse 
calyx lobes, long filaments, and large flowers of peculiar form. It has larger 
flowers, probably, than any other species of the genus. 
7. Leiphaimos simplex (Griseb.) Standl. 
Voyria simplea Griseb. in Seem, Bot. Voy. Herald 170. 1854. 
TYPE LOCALITY : Woods near Ancon Hill, Panama; type collected by Seemann 
(no. 665). 
Stem simple, slender, one-flowered, with a solitary abbreviated scale inserted 
at the middle; bracts and calyx limb none; corolla salverform, its eylindric- 
campanulate tube twice longer than the oblong obtuse blue lobes; ovary short- 
stipitate. * 
This species is not represented in the recent collections. According to 
Hemsley ' it was collected also by Hayes (no. 236) in damp woods hear Empire 
Station. The species is said by Grisebach to be closely related to Voyria nuda, 
a plant described by Splitgerber from Surinam.” The latter belongs to the sub- 
genus Disadena, but Grisebach does not indicate that the ovary of Voyria 
simpler is glanduliferous, so perhaps it may not belong to this group. 
8. Leiphaimos azureus (Karst.) Gilg in Engl. & Prantl, Pflanzenfam, 42: 105. 
1895. 
Biglandularia azurea Karst. Linnaea 28: 417, 1856. 
TYPE LOCALITY: “Crescit locis humidis umbrosis, altitudine 1,000 metr. 
radicibus Galactodendri adhaerens ad pedem septentrionalem montis ‘Cumbre 
de Valenzia’ prope Puerto Cabello,” Venezuela.
