DESCRIPTION OF SPECIES. 39 



The specimen represents a cvlindrical ovate spathe of a monocotyle- 

 donous plant like an Aristeiua. It may be compared by its form and size 

 to Ottelia parisiensis, figm-ed by Saporta in liis Monde des Plantes, p. 227. 

 The borders of the specimen seem to have been compressed and the nerva- 

 tion deformed. It is rather a spike, however, than a pei'icarp.

Smilax undulata, sp. nov. 

 PI. XLVI, Fig. 2. 



Leaf membranous, thin but hard, ovate, acuminate, rounded at base 

 in narrowing to the midiib, which it joins in decurring to it, entii*e, tlu-ee- 

 nerved, midiib naiTOw, straight; lateral nerves emerging from the base, 

 ascending midway between the borders and the midi-ib, undulate, acrodi-ome. 



The tertiary nerves, or nervilles, are very distinct and strong, passing 

 obliquely upward from the midrib to the lateral nerves, then in the same 

 direction from the lateral nerves to near the borders where they curve in 

 oblong areoles, traversed by branches at right angles or in an oblique di- 

 rection, forming an elongated, very loose areolation, most like that of some 

 water plants (the Alismaceae, for example), or like that of some fossil leaves 

 referred to Smilax, such as S. Haidinijeri Ung. (Sylloge, pt. 1, p. 7, PI. i. Fig. 

 11); S. Tarigonii Graudiii (Contrib. Fl. Foss. Ital., 2d Memoir, p. 59, PI. x, 

 Fig. 5). 



The leaf is about 7"" long, S"" broad at the middle. Except that it is 

 not cordate, it much resembles, especially by its nervation, S. siibhispkla 

 Muhl.
