11. Arundo reperta, sp. nov. 



Stern thick, articulated ; surface striated, marked with round, obtuse 

 knots, either placed on the articulations or here and there upon the 

 stem, without normal distribution ; ear of seeds crushed, representing 

 lanceolate glumes, sharp -pointed and rounded at base, and ovate-lanceo- 

 late-acute seeds, truncate at the base, with the center elevated or con- 

 vex, apparently covered with a coating of hairs. The glume is longer 

 than the seeds, and nerved in the middle. 



Habitat.— Green Eiver, west of the station, Br. F. V. Hayden. 



12. Arundo obttjsa, sp. nov. 



Though the specimen is not as well preserved as that of the former 

 species, the characters of the organs which it represents are discernible, 

 and indicate a marked specific difference. The strise or primary veins 

 of the small fragment of a branch are thick, more distinct, and evidently 

 separated by four or five thinner secondary veins : the glumes and pallets 

 are shorter, equally striate, without middle nerve, and the seed is much 

 shorter, broader, obtuse at one end, •and truncate at the other. The 

 fragment which I consider a pallet is slightly emarginate or truncate at 

 the poiut. 



Habitat. — Golden, South Table Mountain. 



13. Palm acites Goldiantjs, sp. nov. 



Species representing a large fragment of a flabellate leaf with five to 

 nine rays on each side, of a flat, narrow, linear racbis. Rays averaging 

 one and a half centimeters broad, marked by deep, narrow furrows, 

 without costsB, joining the rachis in an acute angle of twenty degrees, 

 united to it by their whole undiminished base, without decurring along 

 it. Surface somewhat shining ; substance thick ; primary veins distinct 

 at least; in some places, where the epidermis is destroyed, two to two 

 and a half millimeters distant, separated by ten secondary veinlets, thin, 

 but often discernible to the naked eyes. 



Habitat. — Golden. 



14. Sabal communis, sp. nov. 



Leaves of medium size, borne upon a nearly fiat or merely convex 

 petiole, its top passing at the upper side into a short acuminate rachis, 

 while on the lower side it is cut horizontally or nearly truncate ; rays 

 not very numerous, the lowest in right angle to the rachis, not descend- 

 ing lower than its base, rapidly enlarging, carinately folded near the 

 point of attachment to the rachis, becoming mostly flat or scarcely 

 carinate upward ; caiinse narrowly costate ; primary veins broad, gen- 

 erally black when the epidermis is removed, one to two millimeters 

 apart; intermediate veins thin and numerous, averaging twelve in the 

 large intervals of two millimeters. This species is closely related to 

 Sabal andegaviensis, Schp. of the Eocene of Angers, France. 



Habitat. — Golden, where it is common. 



15. Mtrica LudwiGtII, Schp. 



Leaves of middle size, subcoriaceous, oblong or linear-lanceolate, 

 gradually tapering into a long entire acumen, distantly and deeply den- 

 tate along the borders ; middle nerve thick ; secondary veins suboppo- 

 site, open, parallel, curving in passing to the borders, camptodrome, 

 forking at the base of the teeth, the branches entering them, while the 

 top of the veins is curved along the borders. 



Habitat. — Green Eiver group, near mouth of White Eiver, Prof. W. 

 Denton.
