OF THE GENUS CUSCUTA.

Var. 8. Tbnorii. Gjplaniflora, Tenore! Syll. FI. Neap. p. 128 and Flor. Neap. III. p. 250, t. 220, f 3 — If I am 
not mistaken, Kunze (Flora, 1846, p. 655, in Plant. Willk. nro. 303) was the only botanist who recognized TenoreV 
plant; every other author has bestowed the name on some other forms of our plant or on some other species. G. 
planiflora, Koch! Germ. p. 570, and Reichenb. FI. Germ. Exsicc. nro. 2069, are forms of (7. Epithymum.— Tenore’s 
plant is most common in Sicily and north Africa, extending to the Canary Islands, to Spain, southern France, Italy 
and the Mediterranean islands, to Greece and Egypt, and undoubtedly also to Asia Minor and Syria. It is one of the 
smallest Guscutce, the heads are compact, 2-3 lines in diameter, white or rose-colored. The turgidity of the almost 
cylmdnc lobes of the calyx and of the laeinise is very distinct even in the dried specimen, and very striking in the 
fresh or soaked one. Flowers often less than 1 line in length; grains very rough, 0.3-0.4 lines in diameter. — This 
is G. alba of most authors, but not of Presl. Succuta, DesM. Et. 41 is a genus founded on an immature 
specimen of the same plant. G. Epithymum , Gussone! Flor. Inarim. p. 212, Cosson! in Plant. Bourgeau [467 (17)1 
and of many authors on plants of southern Europe. 0. Europcea, Bove! in Hb. xMauritan. 149. G. bracteosa , 
Gaspar.! in Hb. 0. microcephala, d’Escayrac! in Hb. 0. Godronii, DesM.! 1. c. 60, is a form with more acute lobes 
oi calyx and corolla. C. Simla, Tmeo ( fide spec, in the Hb. Cesati) is the same .plant with lobes of the calyx a little 
broader. 0. calycina, Webb! Phyt. Canar. III. p. 37, t. 152, has a larger calyx including almost entirely the corolla. 
. Choisy! Mss. is the same thing. — It occurs in many published collections; besides those already men¬ 
tioned it has been distributed by Bourgeau! 491, 1298, 1430, a. etc.; Aucher-Eloy! 1418; Huet de Pavilion! 
Palermo, etc. 
Var. e. papillosa is a peculiar form of the last subspecies, which thus far seems to haveescaped observers ; the 
whole flower is covered with semi-transparent papillae ; otherwise, I find no difference in specimens sent from Algiers 
to the Pans Museum by Balansa! But often the lobes are elongated and acute ; so* in the specimens from Tunis, 
Kralik ! 410, Algiers, Cosson ! Segovia, Hb. Gussone! A specimen from Arabia, Botta! in Hb. Mus. Paris., seems also 
to belong here. G. globulosa, Boiss. & Reut. is very closely allied to this form, and distinguished principally by the 
very short styles, and the globose corolla, the lobes of which cover the capsule ; this form of the corolla does, however, 
occasionally also occur in specimens, which cannot be separated from C. planiflora. 
Y 5. C. Pal^stina, Boissier! Diag. Or. I. 11, 86. — This pretty little species is closely allied to the last, to which 
the author himself subsequently referred it; but it seems to hold its rank with a number of other species of this genus, 
the limits of which are so difficult to ascertain. Tournefort (Cor. 45) already distinguished it under the name of G 
Gretica; it is also G. micrantha, Tineo! in Gussone FI. Sic. Syn. II. 887, not Choisy; and G. capillaris , Reichenb. PI. 
Cnt. V. 64. G. globularis, Bert. FI. it. VII. 625, is the same plant. — It grows on small mostly shrubby plants, on arid 
hills in the Mediterranean region ; in Sicily, Tineo ! Morea, Bory ! Attica, Heldreich! Creta, Sieber! Raulin! and 
other Grecian islands, Leffivre ! etc.; Palestine, Boissier! Gaillardot! Blanche! - Heads only about 2 lines in diameter, 
flowers J-l line long, usually 4-, but often only 3-parted ; only the central or primitive flower of the heads is often 
5-parted; calyx comparatively large, with broad and short carinate lobes ; top of laeinise cucullate ; scales rather large, 
broadly spatulate, incurved; styles somewhat longer than ovary. 
\ / § 2. Styles as long as or shorter than ovary. 
V 6 - c - brevistyla, A. Braun ! in PI. Schimp., and in Richard Tent. FI. Abyss. II. 79, is perhaps too [468 (18)] 
nearly allied to G. planiflora , from some forms of which it is scarcely distinguished but by the short styles, 
which, in fruit, become divaricate. In the original Abyssinian specimens the lobes of the corolla are expanded, in 
some others they are closed over the capsule. The'scales are short, thin and truncate or sometimes bilobed — It has 
been found in Abyssinia, Schimper! III. 1486 ; on the Sinai, Botta ! in Persia, Kotschy! 580 ; Affghanistan, Griffith ! 
686 ; Thibet, Hooker and Thomson! C. elegans , Noe ! in Herb. 518 (not Boissier), from the Tigris, is the same plant. 
Var. ? globulosa. C. globulosa , Boissier & Reuter! in sched.; Boiss. in Diag. Or. II. 3, 126. 0. Balansa;, Boiss. 
& Reut. in sched. - This very pretty form at # first sight looks very distinct; but Boissier himself already suggests the 
propriety of uniting it with “ C. alba” (planiflora), and indeed its papillose flowers greatly resemble the var. papillosa 
described above; on the other hand it approaches G. capitata , but more in external appearance than in essential 
characters ; the pretty red tinge of its flowers is occasionally found in both of these, and may be in some connection 
with the development of the papillae. — The corolla closes over the capsule, giving the flower as well as the whole 
head an obtuse appearance ; the scales in the original specimen are bilobed, in the other truncate ; styles very short. — 
Mountain regions of Asia Minor : on the Tmolus, Balansa! 413 ; on the Taurus, the same ! 707. 
V 7 - C * Europe, L. Sp. 180, excl. var. ( 3 . This well-known and well-characterized specie* offers none of the 
difficulties of all the other European Guscutce; the obconic calyx with its thick and fleshy and usually elongated base 
and thin and obtuse lobes, the thin corolla with obtuse laeinise, the small and very thin bifid or truncate appressed 
scales, the large ovary and comparatively large capsule with short divaricate styles and bearing the dead corolla only 
on top (not does it vary nearly as much as the others do : the flowers how- 
eyejv^rer^'otten 5- as 4-parted.
