DESCEIPTION OF SPECIES— PALM.E 121 



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

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

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

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

 slielly pericarp, of a darker color and smooth, is perhaps slightly stronger than 

 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 (he 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 Sabal 

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

 Sabal, especially of S. Camj)hellii, seems also to point out their reference to 

 species of this genus. 



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



Paliuocarpon corriigatuni, sp. uov. 

 Plato XI, Figs. 10-and 11. 



Fruit hard, enlarged in tlio middle, truncate at one end, slightly narrowed and obtuse at the 

 other, ribbed iu the length, deeply rugose across. 



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

 destroyed by maceration; for fig. 10, which has the same characters, differing 

 merely by its smaller size, has the epicarp smooth. The one (fig. 11) is marked 

 in the length by ten narrow costse, 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. 



P a I in o c a r p o n s ii b c y I i n d r i c u in , sp. nov. 

 Plate Xi, Fig. 12. 



Fruit oblong or subcylindrical, truncate at one end, split at the other in two diverging or slightly 

 recurved, pointed 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
