OF THE GENUS CUSCUTA. a7 
scales usually shorter than the tube, sometimes quite narrow. — A southern form, found on the southern declivity of 
the Alps, in Piedmont, Tyrol, Spain (Willkomm! 52, a), in southern France, in Italy (on the Apennines and in Cor- 
sica), in Greece and in the Crimea; I have also seen, in the Kew Herbarium, an English specimen of this variety, 
on Ulex; it has made its appearance in arora on Erica and other evergreen shrubs; this garden form is C. zan- 
thonema of the Paris Jardin des Plante 
Var. y.? oprusata. This very curious form was collected by Funk! (Herb. Cosson and Hb. Reichenbach) in 
the Sierra Notade of Spain on some shrubby Genista ; the glomerules consist of 3-5 flowers, only, on pedicels longer 
than the calyx; lobes of calyx and corolla broadly oval, obtuse, shorter than the tube of the corolla; scales large; 
styles as in the common form. I would at once have acknowledged this peculiar plant as a distinct species, if a 
second specimen had not come to hand, collected by Heldreich on Artemisia near Koniah in the interior of Asia Minor, 
which approaches more to the ordinary form; flowers similar, but smaller, sessile, 6-8 in a small head; 
narrow ; styles erates seeds very small (0.3 lines diam.). The former may be distinguished as var. macropoda, the 
latter as var, ap

as long as calyx ; lobes of calyx obtusish, scarcely as long as tube of corolla; laciniz lanceolate, acute ; 
anthers broadly sagittate ; scales large, crenulate ; styles subulate at base, on the capsule almost eae divari- 
cate. — Tunis, Kralik! Hak’ Cosson and Herb. Mus. Florent.; the only African form of the group of Epithymum seen. 
Var. e. ANGUsTATA. I distinguish by this name an Italian form, which assumes different shapes, described under 
different names. It has narrow and elongated lobes of the corolla and usually also of the calyx, which is commonly 
longer than the tube of the corolla; the flowers are numerous and sessile, or ordinarily more or less pedicelled. Three 
sub-varieties may be distinguished. 
ar. a. alba, with whitish stems, smaller flowers, membranaceous calyx. This is the true C. alba, Presl! Del. 
Prag. 87, also of Tenore and some other Italian botanists, while most authors apply this name to the original .C. plani- 
Aa Ten. Presl’s description, copied by almost every subsequent author, is very erroneous; but his own specimens, 
n Zizyphus, preserved in his collection at Prague, and in the imperial Herbarium at Vienna, leave no doubt about a: 
entity 0 of the plant. C. subulata, Tineo! in Gussone FI. Sic. II. 888, is exactly the same thing, as also C. 
i! in Hb. It is a southern form occurring Riper in Sicily, also about Naples and in Malta ; it is often 
found on Sisnbe and Sieber! (in Herb, Ledebour) gathered it on an oak. 
Var. b. angustissima, flowers longer than in any other form seen (24-23 lines long), on short pedicels, with 
short calyx, slender elongated tube, narrowly lanceolate acuminate lacini, distinctly subulate filaments, and rather 
small scales. In fields of Medicago near Padua, Visiani ! 
Var. c. rubella, with red stems, larger flowers, red calyx of a thicker texture. This is C. planiflora, Koch Fl. 
Germ.; DesM. Et. 54, and many other authors, but not of Tenore. It has often been collected in southern Tyrol on 
Colutea, Artemisia, ete. ; it also occurs in the Abruzzi and in Corsica. 
Var. ¢. Korscnyt. C. Kotschyi, se Moulins! Etudes p. 56 (not C. Kotschyana, Boiss.). C. microcephala, Wel- 
witsch ! in wild: Flor. Lusitan. nro. 1048. — This plant is perhaps the original Epithymum of the old botanists, as it 
often occurs on Thymus and other saat ‘frubendend Labiate. It is well characterized by rather thick red 
stems, the small and dense glomerules, the closely sessile iiwirs; with long acute or acuminate lobes of [464 (14)] 
ealyx and corolla, and rather shorter styles than the common form of C. Epithymum. When the base of 
the ealyx is elongated into a pedicel, it becomes the form just mentioned as rubella. —On the higher mountains of 
southern Europe, the southern declivity of the Alps, the mountains of the Dauphiny, the Pyrenees, the Sierra 
Nevada and other mountain regions of Spain and Portugal; in the Abruzzi of southern Italy, in the attain of 
central Sicily, of Turkey, and of Greece. 
Var. scabrella from Sicily, Gussone! and Arragon, Webb! is a papillose form of the same plant. 
3. C. AByssinica, Richard, Abyss, II. 78, C. macrostyla, Decaisne in Herb. Mus. Paris., seems to be well dis- 
tinguished by the short and thick lobes of the calyx, the very long and narrow, erect lacinix, the small, often bifid, 
scales, and the very long capillary styles. These even surpass those of the last species, while the other characters, 
together with the crowded, closely sessile flowers, approach it to the next one. The typical form was collected on 
Lantana; another, with shorter laciniz, was gathered on a leguminous shrub. 
C. PLANIFLORA, Tenore, sensu latiori. This name has, like that of C. alba, suffered under the misfortune 
scarcely ever to be applied to the species on which the author originally bestowed it! The difficulty was increased 
by an incomplete description, and by Prof. Tenore himself inadvertently distributing under his new name a form of
