404 GEOLOGICAL SUEVEY OF THE TEREITORIES. 



DoMBEYOPSis TEiviALis, Lesqx. 



Tbis species is described in Haydeu's Eeport for 1872 (p. 380) from an 

 imperfect specimen. We have now a nearly entire leaf, 3-palmately' 

 nerved, round-square in outline, obtusely 3-5-Iobed, the two lateral prin- 

 cipal lobes short obtuse, the middle one broad, nearly round, base of the 

 leaf deeply cordate or auricled, marked by two simple marginal veinlets 

 coming out from the round point of attachment of the petiole, and de- 

 scending- toward the borders of the auricles. The three primary nerves 

 are ramiiied, the lateral bearing two or three outside branches, the 

 middle one a few alternate pairs. The nerves, at least the primary 

 divisions, are craspedodrome ; their largest branches also ascend to the 

 point of the lateral shorter lobes. Besides the analogy of form of this 

 species with Ficiis Domheyopsis, Heer, remarked in the first description, 

 {loc. cit.,) its relation to I). tridenSj Ludw., (Paleont., vol. viii, p. 127, 

 PI. xlix, Figs. 2, 3,) is noticeable. 



Hahitai. — Golden, in the white sandstone overlying the lowest coal- 

 beds. 



DOMBEYOPSIS GIlANDIFOLIA(?) Uug. 



A mere fragment, referable to this species described by linger in Fl. 

 V. Sotzka, (p. 45, PI. xxvii. Fig. 1.) This fragment shows six principal 

 veins from the flattened top of a thick striate petiole, with strong ner- 

 villes, dividing in the middle of the space between the veins, and form- 

 ing large, square, or polygonal areolae. The specimen is, however, too 

 fragmentary to allow a satisfactory comparison. 



Habitat — Golden, South Table Mountain. 



ZlZYPHUS DISTORTUS, sp. nov. 



Leaves large, membranaceous, entire, at least near the base, where only 

 the borders are distinctly preserved, round obtuse, enlarged on the 

 sides, abruptly rounded and slightly cordate to the petiole, palmately 5- 

 nerved from the base; middle nerve simple, not branching; lowest 

 veins thin, merely marginal veinlets; middle pair of lateral nerves 

 divided in 3 to 4 branches curving upward ; nervilles close, numerous, at 

 right angle to the middle nerve; petiole comparatively long, 2 centime- 

 ters. The nervation of this species is similar to that of Z. plurinervis^ 

 Heer, (Flor. Tert. Helvet., Ill, p. 76, PI, cliv, Fig. 31,) as marked upon the 

 right side of the leaf; the secondary veins are, however, less numerous, 

 more distant, longer, and in a more acute angle of divergence ; the mid- 

 dle nerve has no branches ; and the nervilles are closer, numerous, par- 

 allel, and continuous from the middle nerve to the borders. The leaves 

 are mostly unequilateral, or more enlarged on one side, and irregular in 

 shape, either rounded or more narrowed to the base. 



Habitat. — Golden. 



Ceanothus eibrillosus, Lesqx. 



Species described in J?ieport for 1872, (p. 381,) from imperfectispecimeus. 

 Others of the same kind have been obtained; one shows a deeply cor- 

 date base, broader than any of the same species, 7-nerved from the 

 base; external veins merely marginal and simple, the lateral ones 

 branching, especially in the upper part of the leaf; surface crossed 

 by close, distinct nervilles, in right angle to the veins, continuous. 

 This leaf is coriaceous, and does not show any trace of areolation ; ilie 

 nervilles are scarcely half a millimeter apart.
