SPHENOLEPIDIUM. 203 



comparison with. Frenela is made. Possibly Yokoyama's Japanese 

 species, Cyparissidium (?) Japonicum, 1 may be closely allied to 

 S. liurrianum, but the preservation of the specimens is too 

 imperfect to allow of any satisfactory comparison. We may 

 define the species as follows : 



Branching alternate ; leaves ovate, acuminate, or triangular ; 

 keeled dorsally ; cones small, borne on clusters of short slender 

 branches, globose or oblong ; scales broad and short, thick, with 

 au elongated lozenge-shaped depression at the apex. 



V. 2313. PI. XVII. Figs. 8 and 8. 



This specimen appears to be practically identical with that 

 figured by Schenk in his pi. xxxviii. figs. 10 and II. 2 The 

 oblong cone and the broad scales with the elliptical transversely 

 elongated scars are well shown. The leaves of the fertile 

 branches have an elongated oval form, with acute tips, and are 

 closely adpressed to the stem. The cone is similar to that figured 

 by Heer in pi. xiv., 3 but in his specimen the leaves are less 

 adpressed to the branch. Compare also Fontaine's S. Virginicum ; 

 this species may, however, be identical with S. Sternbergianum.

V. 2316^. PI. XVIII. Fig. 1. 



This specimen shows very clearly the connection between the 

 thicker and more slender branches. Compare the thicker portion 

 with V. 23166. Ecelesbourne. Ruff or A Coll. 



V. 2316. PI. XVII. Fig. 7. 



The clustered fertile branches and small cones represent a 

 characteristic feature of the species, and may be compared with 

 those of such a recent plant as A.throtaxis laxifolia. Cf. 

 V. 2313, etc. 



V. 23136, V. 2316rt, V. 23166. Cones ; some with fairly well- 

 preserved scales.

 preserved leaves. This specimen, if examined without reference
