402 GEOLOGICAL SURVEY OF THE TEEKITOEIES. 



Ehamnus kectinervis, neer. 

 The same form as described in Kept. 1871, p. 205. 



RnAMNUS OBOVATUS, Lsqx. * 



Represented in two badly preserved specimens. They are, however, 

 easily ideuiifiable. 



Ehus Evansii, Lsqx., Rept. 1871, p. 293. 



The specimens are of the same size and form as those described in the 

 report. 



JuGLANS RhajMNOIDES, Lsqx., Rept. 1871, p. 293. 

 Already described from the same place. 



Carta antiquorum, Newb., Rept. 1871, p. 294. 



I found a large number of well-preserved leaves referable to this 

 species, some larger still than the one formerly described. The general 

 form is of the same type as that of Jnglans rugom. ; the borders of the 

 leaves, however, are crenulate and the secondary veins craspedodrome, 

 their points and their divisions entering the crenules, the lowest ones 

 after curving along the borders. There is a great variety in the nerva- 

 tion of these leaves. Their substance is thickish, subcoriaceous. 



Cassia concinna, Ileer, Flor. Tert. Helv., Ill, p. 122, PI. xxxviii, Fig. 41. 



The figure given by Heer represents a branch of apparently unfolding 

 leaves. We have one specimen with a single leaf so remarkable in form 

 and so exactly simihir to that figure enlarged, 41*^, loc. cit, that it is 

 impossible to doubt that it represents the same species. It is, however, 

 uncertain if these leaves represent a species of Cassia. The young 

 branches of Pcltophornm acluatuni, Gr., of Cuba, bear leaves of exactly 

 the same form. The half opened buds of our Gleditschia triacauthos 

 have also their leaves of the same kind. 



CALYCITES IIEXAPHYLLA, SJ). 710V. 



An open calyx or involucre of a detached fruit, at the top of a slen- 

 der pedicel. Tlie point of attachment is round, 4 mill, wide, with a cen- 

 tral small mamilla 1 mill, broad ; the follieule divides at a short distance 

 from the central point in six linear, entire, undulate, obtuse segments, 2 

 cent, long from the central point, "diverging star-like, coriaceous and . 

 narrowly striate in the length. The central point evidently marks tliis : 

 vegetable as representing a calyx, rather than a coriaceous corolla. It 

 may be compared to what Dr. Kewberry has named CaJijcites pohjsepala, , 

 though the form of the divisions is far difterent. It is apparently refer- 

 able to an involucre or persistent calyx of some Lauracew, or perhaps oft 

 some Biospiros, though few species of this genus Lave hexamerous;^ 

 divisions.
