Et. 64. This well-known and very distinct species of the flax fields of Europe (Russia! Sarbden! rag [471 (21)} 
many! France! England! Ireland! Spain! Sicily!) extends into the Canary Islands (Webb! Finlay!) ar 
Egypt (Kralik ! Figari !), and has also been seen in the eastern parts of the United States! I have seen no s specimens 
from Asia; but Roiinnghie C. aggregata, Fl. Ind. I. 447, “introduced into the Botanic Garden of Calcutta with 
flax from Bagdad,” is most probably the same thing. 
The characters relied on for a generic separation of this species from Cuscuta are untenable, or are founded on 
mistake. The calyx is deeply 5-lobed, not 5-sepalled ; the capsule is constructed exactly as in the allied species ; the 
dissepiment is complete till, at maturity, the larger, lower, obcordate part separates from the upper substylar portion. 
The intrastylar aperture penetrates into the capsule only at full maturity, by a slit parallel to the dissepiment, and 
sometimes by a second transverse one. The stigma is at the flowering period almost twice as long as the style, and at 
base of the same thickness, slightly tapering to an obtuse point ; andy § in fruit, when the style is shrivelled, the stigma - 
has the appearance of being club-shaped. 
The very short style, the shape of the thick stigma, and the structure of the stvlar part of the dissepiment indi- 
cate a close alliance to the Asiatic apoctes, a below, though all these have pedicelled, and not, like our species, 
closely sessile flowers. It is not imp that it originally came from Asia or from Egypt. 
Sect. 2. EPISTIGMA. 
Styles none, or consisting of a very short knob on each half of the ovary; stigmata cylindric or subulate, usually 
of the length of the ovary. The capsule separates from the base only at complete maturity, in a ragged line, not by a 
regular joint ; the opening is wide (C. pedicellata) or very small (C. Arabica, C. pulchella); the emarginate dissepiment 
remains in the base of the capsule, as in Hucuscuta; the withered corolla closely coats the capsule. 
The distinctly pedicelled flowers are disposed in loose or compact umbelliform clusters, few-flowered or crowded, 
supported by a single bract. 
The nei belonging here are all Asiatic. C. Arabica extends into Egypt, where it seems to be the most 
common form 
This es constitutes the _— link between Eucuscuta and Callianche,— another Asiatic form, in which 
the little remnants of the styles are unit

the large she Nitsa long) flowers with a large, loose, cup-shaped calyx and acuminate lacinie ; fruit ea [472 (22)] 
kno outhern Persia, Kotschy! 749. I refer here a specimen from the Herbarium of the 
Pacitoarg Botanic Garden, collected in Armenia by Szovits, though the flowers are a little smaller ses the calyx is 
rather more deeply divided. 
12. C. PULCHELLA, n. sp.: umbellis laxis paucifloris bractea ovata acuminata suffultis ; calycis carnosi lobis 
ovatis acutis corolla tubum subsequantibus ; laciniis tubo fere equilongis ovatis acutis papillosis crenulatis erectis seu 
patulis ; staminibus brevioribus, antheris ovatis filamenta subulata equantibus; squamis angustis faucem attin- 
gentibus fimbriatis incurvis ; stigmatibus ovarium globoso-ovatum apice subconicum squantibus ; capsula corolla 
connivente tota involuta apertura parva basilari demum dehiscente. 
Var. 8. ALTaIca: calyce profundius fisso; laciniis acutioribus ; squamis minoribus sepe bifidis. 
Affghanistan, Griffith ! 688-691, in Hb. Hooker, on Alhagi, Peganum, Artemisia, etc. B. Sarepta! originally 
from the Hb. of Pallas, and Altai, Sievers! both in the Herbarium of the Botanie Garden of St. Petersburg. 
Griffith’s plant, which may be distinguished as a. Affghana, has beautifully bright red stems and flowers, the very 
fleshy calyx especially is bright colored ; umbels 4~6-flowered, pedicels as long as calyx or as the whole flower; 
flower 1} lines long ; capsule opening late and with a very small circular aperture. — From C. Kotschyano it is distin- 
guished by the much smaller flowers with longer pedicels, the deeply divided calyx, the ovate and not acuminate 
laciniee. — The Altaic specimens may possibly constitute C. Asiatica, Pallas, but the specimen in Hb, H. B. Petropol., 
labelled thus by himself, belongs to C. planiflora, var. approximata. 
13. C. pepicettata, Ledeb.! Fl. Altaic. I. 293, Icon. t. 234; DC. Prod. IX. 453, excl. syn. — The smallest 
flowered species of this section ; flowers scarcely 1 line long, whitish, of very thin texture ; scales small, truncate ; 
styles almost united at base, separating in the ripe fruit; intrastylar aperture transverse to the dissepiment ; top of 
thin capsule separating from the base with a very large opening, rather irregularly torn ; more closely allied to the 
next than to both other species of this section, distinguished from it principally by the much smaller flowers and the 
wide opening of the ripe capsule. I have seen no other specimens but Ledebour’s own, collected on the Altai, 
on some species of Galiwm. The other specimens referred to this species by authors do not belong here.
