T. G. YUNCKER 
(WITH THREE TEXT FIGURES) 
In studying collections of Cuscuta from Mexico three species 
have been discovered which, it is believed, have not been 
hitherto described. Descriptions of these new species, together 
with camera lucida sketches, are given below. With the addi-' 
tion of these the number of species of Cuscuta now known to 
occur in Mexico is thirty-six. 
Cuscuta dentatasquamata sp. nov. 
s medium to slender. Flowers reddish, 3-4 mm. long, 
on Soirée shorter than or mostly about equal to the ieee 
in rather compact, cymose clusters; calyx deep, lobes exceeding 
the corolla tube, triangular, acute, slightly overlapping at the 
acute, upright or spreading, shorter than the tube and with 
sli ghtly uneven margins; stamens shorter than the corolla lobes, | 
filaments stoutish and about equal to the oval or orbicular 
anthers; scales about reaching the stamens, dentate, with

few processes, bridged at about the middle, not firmly adherent 
to the corolla; styles slender, about equal to, or longer than, the 
depressed- globose ovary. Capsule large, diepressed plobose, 
thin, somewhat irregularly circumscissile, carrying the ea 
corolla about it; seeds about 1.5 mm. long, globose, two to fou 
in each capsule, hilum oblong, transverse. 
This species falls in section EUGRAMMICA, subsection LEPTI- 
LOBAE, near Cuscuta Choisiana Yuncker. It differs from that
