DESCllIPTION OF SrECIES— PALM^ 121 



The largest specimen of var. major (fig. 7) measures seventeen milli- 

 meters across, from side to sidc^ and ten millimeters only from the truncate 

 base to the top; one specimen, which seems intermediate between both varie- 

 ties, is only fourteen millimeters broad and eight millimeters high. The 

 shelly pericarp, of a darker color and smooth, is perhaps slightly stronger tlum 

 in the former species; nevertheless, the specimens are generally crushed and 

 flattened by compression. The var. minor (figs. 8 and 9) is represented by 

 nutlets one centimeter across the widest part and five to six millimeters in 

 the other direction, generally in a better state of preservation, but with the 

 same thin pericarp of the same color. The characters of these small nuts 

 refer them to Sabal, some species of which have racemes of fruits of the 

 same form, surrounded with an outer envelope easily crushed and of soft 

 texture. Figs. 8 and 9, for example, closely resemble the seeds of Sahal 

 Mexlcana, Mart. The connection of these fruits with fragments of leaves of 

 Sabal, especially of S. Campbeliii, seems also to point out their reference to 



species of this genus. 



Habitat.— Golden, Colorado; not as commonly found as the former.

 Plate XI, Figs. 10 and 11. 

 Fruit hard, enlarged iu the middle, truncate at one end, slightly narrowed aud obtuse at the 

 other, ribbed iu the leuffth, deeply rugose across. 



This kind of nutlet seems, at least in fig. 11, to have its pericarp half 

 destroyed l>y maceration; for fig. 10, which has the same characters, differing 

 merely by its smaller size, has the epicarp smooth. The one (fig. 1 1) is marked 

 in the length by ten narrow costaj, and across by deep irregular wrinkles. 

 It is one and a half centimeters in diameter, and from the exact similarity 

 of form I consider it as representing the same species as fig. 10. The rela- 

 tion, however, of these fruits to living species of Palms is as yet uncertain. 



Habitat.— Golden, Colorado; with the former.

Plato XI, Fig. 12. 



Fruit oblong or subcylindrical, truncate at ouo end, split at the other iu two diverging or slightly 

 recurved, poiuted lobes, distantly and obscurely veined toward the base. 



As seen from the figures, these fruits vary in size from ten to fifteen 

 millimeters broad in the middle, though generally of about the same length, 

 or two centimeters from the border of the truncate base to the points of the
