and disposed quincimcially. The scars are large and round, and 

 the ribs near converge towards them with their upper and 

 lower extremities. The same thing is seen in the leaf scars, but 

 then the converging ribs are less numerous, and there are never 

 more than three. From the Drummond Range I have a very fine 

 series of these plants, as will be seen from the accompanying 

 specimens and figures, which place the nature of the fossils beyond 

 any doubt. The occurrence of this species has been known for 

 some time,' through the labours of Dr. Feistmantel, but the 

 discovery of the roots and stems was first recorded in a paper by 

 the author,* 1 who received many specimens from Mr. Phillips, at 

 Bobuntungen. These roots and stems seem to abound in the 

 strata, and there are some portions of the stone which is made up 

 entirely from the stems. Nevertheless, leaves are rarely found 

 associated with them ; in fact none of the more tender plants — 

 such as Ferns, or organs of plants — are found in these strata where 

 Lepidodendron occurs. In the neighbourhood of the) shales, leaf 

 impressions and those of Ferns may be found ; but these I have 

 not as yet been able to examine. 



The strata I regard as lower Carboniferous, and they are very 

 extensively developed in this locality, where the whole eastern 

 face of the range is composed of beds dipping by a regular and 

 slight inclination to the westward. 



Annularia (Brongniart). 



Herbaceous plants. Stem articulate, subulate, divided by a 

 solid diaphragm at the joints ; branches pinnate and bi-pinnate ; 

 leaves, many in oval whorls, lingulately, elongately, and spathu- 

 lately lanceolate, somewhat thick, with a central nerve, horizontal 

 or recurved ; spikes distichous or verticillate, cylindrically elongate, 

 rachis thick, with short sulcate internodes ; bracts numerous, rising 

 erect, flat below, then erect and lanceolate. Sporangia axillary, 

 globose, or lenticular. 



These were probably herbaceous aquatic plants, whose leafy 

 branches floated. The internodes were hollow and separated by 

 Roy. Soc. N.S. Wales, 1882. Read at the meeting, Dec. 6. In this 



paper are the figures here referred to.
