The lower pair follows the border as slightly thinner marginal vinelets. I do 

 not know of any leaf to which this is comparable ; by its nervation it seems 

 to have a distant relation to the former ; its consistence is as thick, but the 

 surface is smooth or polished. 



Myrica obtusa, sp. nov., PL xxix, Fig. 10. 



Leaf thick, coriaceous, shining, linear, obtuse, entire ; medial nerve thick; secondary veins thin, 

 nearly at a right angle to the medial nerve, curving near and along the borders in marginal festoons, 

 anastomosing from the middle or above with intermediate shorter veinlets. 



The fragment shows the upper part, 5£ centimeters long, of a narrow 

 linear obtuse leaf, only 12 millimeters wide. The secondary veins about at 

 right angle, not quite parallel, and also variable in distance, are extremely 

 thin, undulating, in passing up to the border which they follow in successive 

 curves, anatomosing with the divisions of intermixed shorter vinelets, which 

 come out of the medial nerve under a different angle of divergence, and form- 

 ing a mixed small quadrate or polygonal areolation. The leaf, by its form and 

 nervation too, is somewhat similar to Andromeda venulosa, Sap., Ets., Part 

 ii, p. 3, PI. iv, Fig. 15, whose details of nervation are admirably figured 15 l \ 

 The direction of the secondary veins to and along the borders, the mode of 

 branching with intermediate shorter veins of a more open angle, the very 

 small irregular quadrate or polygonal areolae are still more related to the same 

 characters of some species of Myrica, as M. major, Thun. of Japan especially. 

 The leaf is as thick as that of M. venezuelana, Rich of Cuba.

Myrica? semina, PI. xxvii, Fig. 4 and 4 a . 



The specimen figured represents a hollow stem 2 centimeters wide, 

 cylindrical, irregularly costate rugose on the outside, marked inside with 

 points or small perforations ; walls of the tube 3 millimeters thick. This 

 hollow stem is comparable to a branch of Sa?nbucus deprived of its pith. The 

 same specimen is furrowed by the impressions of branches crossing at right 

 angles with a number of seeds, which, as seen in Fig. 4 enlarged, are oval- 

 pointed and surrounded by a narrow border. These seeds are similar to those 

 figured as seeds of Myrica in Heer Kride Fl. v. Qued., PI. iii, Figs. 15-18, 

 which are found in the same clay beds with leaves of Myrica schenkiana, 

 Heer, (loc. cit, p. 11, PI. iii, Fig. 1.)
