the whole frond quicklybreaks up and melts to jelly when put into fresh-water; thecolour also is paler and more fugacious, and the fructificationquite different. The present is a genuine Wrangelia, a genuswhich has many beautiful species in Australia, where it appearsto reach its maximum of development, both as to number andsize. These several species exhibit considerable variety of as-pect, while agreeing in fruit and in essential character. Someresemble Callithamnia, others Dasyce, others Spyridice, othersGriffithsia and Haluri; it is difficult therefore to say whichshould be regarded as the central groups. As this work pro-ceeds we shall figure the more remarkable, omitting those alreadyfigured in the Flora Tasmanica. Fig. 1. Wrangelia Halurus,—the natural size. 2. A joint bearing a ra»?e^ZM5jwith tetraspores. 3. Portion of the same. 4. Short branch, with whorledramelli and a cystocarp. 4. Tuft of spores from the cystocarps:—thelatter figures variously magnified. ?,jf^ :.JlIi.
