PraTe XXXV. 
CYTINUS Hypocistis, Linn. 
Natural Order CYTINES. 
Gry. Cuar.—Flowers moncecious, bractate. Perianth campanu- 
late ; estivation imbricate. Stamens adnate to a central column, which 
is united with the divisions of the perianth. Ovary inferior, 1-celled, 
8 multiovulate parietal placentas. 
Srzc. Cuar.—F lowers sessile, forming a capitulam. Bracts imbri- 
cate, fleshy below, frequently scorched at the tips, two at the base of 
each flower. Growth parasitic on Cistus. 
Oytinus Hypocistis, Linn. Sp. Plant. p. 566; Gren. et Godr. Fl. de 
Fr. ii. 71; Woods, Tour. Fl. p. 324. 
Hasirat.—Dry ground under Pine-trees. May. 
RemarKs.—The relation in which Cytines stand to other plants has 
been very much canvassed, as, though their habit is that of Orobanche, 
Phelypea, etc., the structure of the flowers is essentially different. No 
sooner had Lindley constructed his class Rhizogens, which he con- 
sidered as intermediate between Cryptogamous and Endogenous plants, 
and in which he placed Cytinesw between Balanophoress and Raffle- 
siaces, than he was met by most decided opposition in the very highest 
quarters. Both Robert Brown and Griffiths wrote at length (Trans. of 
Linn. Soc. xix.): the former placed Cytinus in a section of the Natural, 
Order Rafflesiaceze, along with the wonderful Rafflesia Arnoldi, and re- 
marked (p. 229) that “the section Cytinez seems to be unquestionably 
related to Asarinex;”’ the latter declared himself adverse to the adop- 
tion of the class Rhizanthes, in which he says, ‘‘ a remarkable diversity - 
of character has been sacrificed to an appearance resulting from the 
parasitism on roots and to an assumed absence of any ordinary form of 
vegetable embryo.” At the time when these discussions took place, 
scarcely anything was known of the structure of the seeds of Cytinus, 
and I much regret that I have never been able to procure ripe fruits 
myself. I must therefore refer to Grenier and Godron (Fl. de Fr. p. 
70) for the following information :—‘ Fruit sec ou bacciforme, unilocu- 
laire, pulpeux intérieurement. Plusieurs graines logées dans la pulpe 
a teste dur coriace charnu. Embryon droit.” I have followed Grenier 
and Godron (who coincide with Robert Brown) in placing Cytinez 
among Dicotyledonous plants, believing their affinity to be nearer to 
Asarum and Aristolochia than to Fungus or Marchantia. It has been 
said that Cytinus resembles Fungi in the manner of its decay, but this 
is not strictly true, as the remains of its scales and stem may be found
