12. Arundo obtusa, S2). no v. 



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 strias 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 pallefc is slightly emarginate or truncate at 

 the point. 



Habitat. — Golden, South Table Mountain. 



13. PALMACITES GOLDIANUS, sp. 710V. 



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

 nine rays on each side, of a iiat, narrow, linear rachis. Eays averaging 

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

 without costcT, 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. Flabellaeia C03IMUNIS, sp. nov. 



Leaves of medium size, borne upon a nearly flat 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; carinas narrowly costate; primary veins broad, 

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

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

 large intervals of two millimeters. 



Habitat. — Golden, where it is common. 



15. Mykica Ludw'igii, 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 subopposite, . 

 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. Benton. 



16. Myrica Saportana, sp. nov. 



Leaf membranaceous, large, narrowly-oval or obloug acuminate, piu- 

 nately-lobed ; lobes short, entire, turned upward, triangular-acute; lateral 

 veins open, slightly curving in passing to the point of the lobes ; tertiary 

 veins nearly as thick as the secondary ones, forking uudertheacute sinuses 

 of the lobes, the branches ascending along the sides ; areolation large, 

 polygonal, formed by the anastomosis in the middle of the areas of 

 nervilles at right angle to the veins. There are of this beautiful species 

 two fragments of leaves, indicating the average size of ten centimeters
