[MATTHEW] A REVIEW OF THE LITTLE RIVER GROUP 123 



length of the leaves or less, stems ribbed, with scars of verticillate 

 branches at the nodes. 



The attitude of the leaves, the close joints and the stoutness of 

 the rachis in the smaller hranches of this plant, would lead one to 

 suspect it might be a Palfeostachya, but though carefully looked for, 

 no sporangia were found in the axils. The branching of these little 

 stems is frequent and there seem to be only 4 to 6 leaves on them at 

 a node. In the larger branches there are eight leaves in a whorl and 

 these are longer and the nodes further apart than in the more numerous 

 small whorls ; these leaves and whorls are each about 4 mm. long. 



Horizon and Locality. — From the horizon of Bed 1. Barrack Point. 

 St. John. 



This species was originally collected by the author from a black 

 carbonaceous shale at the south end of the city of St. John at the top 

 of the Dadox^-lon sandstone, and would be at about the horizon of 

 Hartt's Plant Bed Xo. 1 at Fern Ledges. Sir "William stated that he 

 found it in material from Carleton (probably from Hartfs Bed Xo. 2, 

 where the author also collected a closely allied, but not the typical 

 form), 



Mr. Geoffrey Stead collected from this bed good examples of this 

 allied form, wliich may be described as follows : — 



VAR. Plate A'l, Fig. 3^ 



Stem slender branched, about i nun. across; mternodes 4-5 mm. 

 long,, leaves 4 mm. long, linear lanceolate, subulate, radiating from 

 the node at a wide angle, having a faint mid-rib. Branches slender 

 with nodes 2 mm. apart; leaflets linear, subulate, curved, ascending 

 3 mm. long; becoming shorter and the nodes closer towards the tips of 

 the branches. Fructification unJcnown. 



Collected in 1889 by Mr. G. Stead. 



Horizon and Locality. — Bed 2, Fern Ledges Lancaster, X.B. 



This species is retained in Asterophyllites because there is no annu- 

 lus, and because of the rigid, ascending leaves. 



AXXULAEIA, Brongn. 



^fost of the plants described or referred to under this genus were 

 originally described by Sir William Dawson under the genus Asterophyl- 

 lites. 



These plants have a locati^^ed distribution in the strata of the 

 Little Eiver group. Although the stems, leaves and roots of Annularia 

 were found abundantly bv Professor Hartt in his bed Xo. 1, thev have
