Some difference of opinion exists respecting the plant under consi- 

 deration. Prof. Asa Gray, in his list of the Japanese plants collected 

 by Drs. Williams and Morrow,]: referred both F. pllcatum, Thunb., 

 and V. tomentosum, Tluinb., to the North American V. lautanoides, 

 Michx. ; but he subsequently § considered V. tomentosum as more 

 likely a radiate form of F. dilatatmu, Thunb. I believe he was wrong 

 in his reduction of V. plicalum ; for he has himself described V. Inn- 

 tatioides as having sessile eymes,|| and Miquel has well remarked of 

 it**: — "Cynia umbelliformis 4-5-ra(liata inter foliorum par supremum 

 sessilis, qua nota a V. pUcuto aliisque inflorescentia peduncnlata dona- 

 tis statim discernitnr." Notwithstanding this observation, however, 

 the latter author has referred the plant distributed by Maximowicz 

 under the name of F. tomentosnm (apparently regarding it as really 

 identical with Thunberg's plant) to F. plicatiim, as a broad-leaved 

 form, with the remark, ff " umbellis non sterili-plenis sed fructiferis ; an 

 itaque bona species?" I have specimens of this both in flower and 

 fruit from M. Maximowicz himself; it has sessile cymes, and I refer it 

 without the least hesitation to F. lantanoides, my American examples 

 of which differ only in the greater size of the radiant sterile flowers. 

 The Chinese plant, the true F. tomentosnm of Thunberg, is, however, 

 qiiite different from this, and agrees perfectly with Zuccarini's beauti- 

 ful plate. :|:]: Following Miqnel, I regard both it and F. cuspidatn.n 



spicua, Miq., of which I have seen no detailed diagnosis, may rather be the same 

 as my L. samolina. 



* I have ah-eady stated (Ann. Sc. Nat., 5me ser. v. 225) that Champion's 

 Af. coriacea is a mere variety of this, and that tlie typical form occurs in Fokien 

 as well as in Japan.
