DESCRIPTION OF THE SPECIES. 243 



SEQUOIA Torroy. 

 Sequoia cycadopsis, sp. nov. 



Plate CXII, Fij;s. U-U; Plato fXIII, Ki'js. l-J. 



Leafy branches, with keeled stems which were apparently succulent, 

 l)rancliing dichotomously ; leaves remotely placed, alternate to subopj)Osite, 

 widest near the base, decurrent, narrowly linear, acute, varying in length 

 considerably, attaining the maximum dimensions of 3.5'™ in length and 

 2""" in width, margins of the leaves apparently thickened from being rolled 

 slightly, obliquely inserted, the longer leaves straight or slightly curved 

 upwards, shorter leaves (on younger branches I) strongly falcate, all thick, 

 leathery, and rigid, with a midnerve that is prominent on the lower side of 

 the leaves and forms a sort of keel in the longer leaves, showing a sunken 

 central line on the upper side of the leaves. 



Locality: 72d mile-post, near Brooke. 



This plant is very rare. It is in some respects unlike the ordinary 

 forms of Sequoia, and so strongly resembles Cycadites that for some time I 

 thought that it should be placed in that genus, but the finding of branching 

 stems, such as are shown in PI. CXII, Fig. \), shows that it can not be 

 Cycadites. Perhaps it should be regarded as a new genus, but as it stands 

 apparently nearest to Sequoia I have placed it provisionally in that genus. 

 It seems to be a comprehensive form, combining the characters of Cycadites 

 with those of some of the species of Podocarpus, such as P. Meyeriana 

 Endlicher, and P. clonyata E. Meyer. It is also a good deal like Taxitcs 

 falcatus Nathorst (see Floran vid Bjuf, PI. XXII, Fig. 11). In the decur- 

 rent leaves lying strictly in one plane it resembles Sequoia. It is a good 

 deal like Dawson's Cycadites unjiya (see Cretaceous and Tertiary Flora of 

 British Columbia, PI. I, Figs. 2, 2'^). 



Sequoia Reichenbaciii (Geinitz) Heer.

 late, falcate, incurved, acuminate, widest at base; one-nerved.
