PaL^OSTACIIYA ACICULAÏUS, n. sp. 



pose may belong to this species, but they have not been found attached 

 tc its stem or branches. 



The rachis is about 1-| mm. wide, and the nodes about 3 jMn. apart; 

 each node bears several rigid ascending linear bracts about 5 inm. 

 long; in the axils of these bracts there is a short ascending stalk that 

 bears a double spore case (or a single spiral case attached by its bach 

 to the stcdh). Eleven nodes of the spiJce are known. 



Horizon and Locality. — From Bed 1:^0. 2 of Hartt's section at 

 Fern Ledges, Lancaster, N.B., scarce. 



Annulaeia recurva, n. sp. Phite 11, Figs. 1 and 3. 



Only the smaller branches known. These are 2 mm. wide, striated, 

 nodes distant {2bmm. apart). Leaves in fascicles from each side of 

 tlie stem, thick, revolute; about five groups of leaves at a node, and 

 about five leaves, or less, in each group, one nerved, 2 mm. wide at 

 the base and about 20 mm. long. Younger examples with leaves less 

 recurved, have nodes at shorter intervals; the leaves are much fewer 

 en the young shoots, about six on sm,all terminal twigs, where they are 

 3 mm. long. 



The leaves in this species are thick as in A. acicularis, but are 

 shorter in proportion to the internodes, and are strongly recurved.

Annulaeia (?) LiGATA, H. sp. Plate II, Fig. 4. 



Only a few examples of this species are known. 



Stem 4 mm. wide, striate, weak, internodes rather close. Leaves 

 few (4 to 5) at a node, broad, 4 mm. wide, and 2^ mm. [or more) 

 long, and terminating in a mucronate point; they are short lanceolate- 

 linear, 5 nerved and rather abruptly pointed at the end, the nerves 

 converge to the point. 



The leaves of tbis plant spread from a weak internode like those 

 of Annularia, but the numerous veins distinguish it from others of this 

 genus. It is separated from Sphenophyllum by the absence of dicho- 

 tomy from the veins. It may be compared to such species as Annu- 

 laria recurva, and AsteropliylUtes facicidatus, in which the leaves are 

 arranged in tufts or groups around the node; in this, however, it is 

 the nerves that are arranged in groups. This form may be the type 

 of a new genus, but the material is too defective for diagnosis.
