Further Doubtful Species.
P. inequalis St., Spec. Hep., vi, 169. Stephani has two drawings of this. One is an entire leaf, broader than tall, the other a coarsely toothed leaf. This would point to its being either P. conjugata, or, as suggested by Mr. Allison, Adelanthus falcatus; though it is difficult to believe that Stephani would not have recognised the former plant with its opposite leaves. The specimen thus named and mentioned by Helmut Carl as having been examined by him, was from my herbarium. It is really a small state of P. fuscella, with the usual denticulate leaves. It is extremely unlikely that P. inequalis is a good species.
P. appressifolia St., Spec. Hep., vi, 124. From the description and drawing alone, it is impossible to say whether this is P. ramosissima or Adelanthus falcatus. Neither are the data sufficiently convincing for it to be considered a new species.
P. nigrescens St. Spec. Hep., vi, 187. The description of this species suggests that it is a discoloured form of either P. fruticella (Tayl.), or P. pleurota H. f. & T.
P. exilis Col., and P. distans Col., Trans. N.Z. Inst., vol. xxix, pp. 282 and 283 respectively, were not seen by Stephani, nor are they amongst the ones that I have seen. They evidently belong to one or other of the smaller species.
Adelanthus falcatus, mentioned above, was first collected by Menzies, and described and figured in the Musci Exotici. It was classed as a Plagiochila till Mitten discovered the fructification, which is lateral and sub-tubular.
