DESCRIPTION OF SPECIES— PALMiE. HI 



and described by the author, I cannot consider this species as positively iden- 

 tified with that of Boernstaedt, whose rays are hghtly {leviter) carinate with 

 intermediate veinlets sometimes three to eleven, though more generally five 

 to seven, according to Heer's remark. Our specimens scarcely show any 

 trace of carina, the primary nerves being sometimes convex, but they have 

 all the same appearance upon larger or narrow rays; and the intermediate 

 veinlets are four to six in number, rarely seven. In some fragments, as in 

 fig. 8, the nerves are effaced, and the intervals, much larger, are apparently 

 filled by numerous indistinct veinlets. The fragment a to b, fig. 7, apparently 

 represents the same part as that of fig. 5 of Heer, loc. cit., which the author 

 considers as a floral involucre. The veins are all equal, and close to each 

 other. The presence of these fragments among both the European and the 

 American specimens, and their similarity of characters, seem to prove identity 

 of species. 



Habitat. — Golden, South Table Mountain, in a stratum of white hard- 

 ened clay, with Carex Berthoudi. Fragments apparently referable to this 

 species are mixed with Ljjgodkm neuropteroldes ft-om Barrell's Springs.

Frond large, rays convex, semi-cylindrical tovrard the base, flattened in the upper part, diverging 

 from the top of a broad racbis, distinctly nerved; primary nerves distant; intermediate veins thin, 

 close, averaging ten in number ; racbis truncate at its upper face, rapidly narrowed to a point on its lower 



The two figures (1 and 2) are counterparts, and therefore show the 

 two sides of the fragment of a frond and of its petiole. The rachis is flat or 

 about four to five millimeters thick in the middle, cut in a broad angle on the 

 upper side, more elongated on the lower, the prolongation measuring about 

 two and a half ceotimeters, with the tip abruptly and obtusely pointed ; sur- 

 face very narrowly and somewhat irregularly veined lengthwise. Rays all 

 attached to the top of the rachis, round truncate at base, comparatively few, 

 about thirty, diverging on both sides at right angle, deeply carinate, without 

 costae at the upper, half-round surface, rapidly increasing in width, and flat 

 in the upper part of the frond ; carinse broadly costate ; primary veins more 

 or less distant and thick, generally black when the epidermis is removed, 

 one to two millimeters apart ; intermediate veins thin and numerous, ten to 

 twelve in the intervals of two millimeters. I refer to this species the frag-
