Description of the species. T have not yet seen an anthcntie 

 specimen of Jfj/agrop.^is Turncr'i Ki'Tz. Vint the ])hint liere 

 treated answers to the descriptions and ilhistration of Ki'Tzrxci's 

 species in many points. 



KiJTZixr, referred Turner's Fkcus Myagroidca to his genus 

 J/ya(j[7'opsis, calling it Myagrojms Turneri. After a careful 

 examination of the material at hand, I fonnd that Turxer's 

 species should he amalgamated with Cystophyllum sisymbrioides as 

 had heen done hy J. Agardh^^; and that Kutzixg's species 

 accorded fairly well with another plant fonnd in several parts of 

 Japan. This plant has several well marked characters and 

 deserves a specific rank. Hence the name Cystophylhim Turneri 



(KÜTZ.) 



The relative dispositions of the hranches and hranchlets in 

 the present species are identical with the j)receding. But the 

 branchlets are generally less approximate in this species, and the 

 thickening of the basal parts of the stems is less conspicuous 

 and even quite negligible. The stems of the branchlets are 

 filiform, more slender and compressed than in the preceding- 

 species, but occasionally angulate at the thickened portions. 



The leaves are very narrow, hardly attaining l.ô mm. in 

 breadth but frequently measuring 12 cm. in length. They are 

 alternately pinnately divided, with the segments patent and 

 distant, and with a breadth nearly equal to that in the axial 

 part. The midrib is distinct, and traverses the whole length of 

 the leaf, running into the segments \\]) to their apices. 



The vesicles on the lower portions of the branchlets are 

 subspherical, 3.5 mm. in length and 3 mm. in diameter, with a 

 stalk slightly shorter than the length of the vesicles, and coro-
