37. Cuscuta acuta Engelmann 
(PI. II, fig. 8, A-E) 
Cuscuta acuta Engelmann, Trans. Acad. Sci. St. Louis 1: 497. 1859. 
Stems slender. Flowers 2-3 mm. long, on pedicels about as long as 
the flowers, thin and membranous, in umbellate clusters; calyx campanu- 
late, lobes triangular-ovate, acute to acuminate or somewhat cuspidate, or 
obtusish, as long as, or exceeding, the corolla tube; corolla campanulate, 
lobes lanceolate, acute to acuminate, upright or somewhat spreading in 
fruit, as long as, or longer than, the tube, stamens about three fourths as 
long as the corolla lobes; filaments stout, subulate, about equal in length 
to, or much longer than, the oval anthers; scales reaching the stamens, 
thin, bridged below the middle, closely adherent to the tube, fringed about 
the upper half; styles about equal to the globose ovary, slightly subulate. 
Capsule not circumscissile though very easily breaking away at the base, 
carrying the withered corolla about it, very thin and almost transparent in 
some specimens so that the seeds are visible in it, depressed-globose, intra- 
stylar aperture comparatively large, styles upright or more often becoming 
divergent; seeds about 1 mm. long, ovate, hilum short, oblong. 
This species differs from C. pentagona, which it resembles somewhat, in 
the shapes of the filaments, calyx and corolla lobes, and the divergent styles. 
Type locality: 11 Chatham Island of the Galapagos group.” Distribution: 
Galapagos Islands. 
Specimens examined: Galapagos Islands: Chatham Island (Andersson, the type, a 
fragment in the Engelmann herbarium); South Marborough Island (Snodgrass and Heller 
318 ); Bindloe Island (Snodgrass and Heller 769). 
38. Cuscuta insquamata n. sp. 
(PL V, fig. 30, A-D) 
Stems slender. Flowers 1.5-2 mm. long, delicate, 4- or 5-parted, on 
pedicels shorter than or longer than the flowers in dense cymose clusters, 
membranous with a few scattering yellow, pellucid glands; calyx longer 
than the corolla tube, lobes triangular, acuminate; corolla shallowly cam¬ 
panulate, lobes upright, triangular, acuminate, about as long as the tube; 
stamens shorter than the lobes, ovate anthers about equal to the stout, 
subulate filaments; scales lacking; slender styles shorter than, or equaling, 
the globose, somewhat pointed ovary, which is thickened at the apex. 
Capsule carrying the corolla about it towards the base, depressed-globose, 
with a fleshy collar about the intrastylar aperture, evidently not circum¬ 
scissile although a few capsules seemed to have a weaker zone towards the 
base where they break loose when pulled; seeds four in each capsule, 
roundish, hilum small. 
Type locality: Bolivia. Distribution: Known only from the type 
locality. 
Specimens examined: Bolivia: (Fiebrig 3045, the type, in the Museum of Natural 
History, Asuncion, Paraguay, a fragment in the author’s herbarium).
