describes, lie (ienomiiiates Ilermodactyluslonsjifolius. That the species is 

 distinct cnoiiuh from Pv'ia tubcrosa, which Mr. fSweet dcnoininatcs Iler- 

 niodiictyhis hispathaccus Cpassiii<; l)y iSalishury's name of H. tuberosus in 

 the //()/■/. TrfDi.t., probably as deeming it not sufficiently distinctive, now 

 that other tuberous species are known), there cannot l)e a question. It 

 is possible, how ever, that questions will arise on the propriety of forming 

 these species into a new genus; and, until these questions are affirmatively 

 answered by the consent of a majority of botanists, we shall retain the 

 species in the genus /^ris.

7Yis longifolia has some of its radical leaves a yard or more in length, 

 and but one flower in a spathe ; 7. tuberosa has much shorter leaves, and 

 has two flowers in its spathe : these are the obvious points of difl^erencc, 

 and there is a sufficiency of minor ones. Mr. Sweet's species of Ilermo- 

 dactylus, then, are these: — I. H. longifolius, Stv. Fl. Gar. 2. s. 146. 

 2. H. repens (creeping-rooted), of which the /Vis tuberosa of Sibthorp's 

 Flora Grccca, 1. 41.; of the JMagnzine of Xatiiral Hktori/, vol. iv. p. 29., 

 and Gardene/s Alagazine, vol. viii. p. 235., the cut in both these places 

 having been copied from that in Flora Grceca, 1.41.; and of Redoute's 

 LUiacecs^ t. 48., are synonymes. It will be remembered that, in p. 235., 

 we remarked that the figure there (copied from that in Flora Greeca) 

 differed completely in its " scaly creeping sucker (propago) at its root," 

 from the /Yis tuberosa we had always known : the truth of this remark is 

 now corroborated by the experience of Mr. Sweet ; the /Vis tuberosa we 

 had all along previously known being his third and following species. 3. 

 II. bispathaceus, of which the />is tuberosa of Jiot. j\Iag. 531., of Link's 

 Enumeratw, and of Smith's Herbarium, are synonymes ; as well as Hermo- 

 dact\ lus tuberosus of Salisbury, in Ilort. Trans., vol. i. |). 304. In addition 

 to our remarks (Vol. VIII. p. 235.) on the culture of the last-named species, 

 this observation by Salisbury may be of interest : — " In a border of deep 

 rich loam, at Chapel Allerton, it flow ered every year : at Mill Hill, on a dry 

 gravel, it never flowered." It has again flowered finely, this spring, in 

 the Bury Garden, under the treatment described p. 235. ; and the plants 

 from the wild station near Plymouth have, this s|)ring, flowered in the 

 Cambridge Botanic Garden. Should the specific ilistinctness of the three 

 kinds above named become admitted, of which there is probably very 

 little doubt, the geogra[)hical station of each species w ill then be desirable 

 to be known. Salisbury says of H. bis])athaceus Swt., " it grows in the 

 Peloponnesus ;" but the fact of II. rejicns being the species figured in 

 Flora Grccca, excites a doubt whether Salisbury's habitat does not apply 

 rather to II. repens than to II. bispathaceus. After all, may it not be 

 purely by error that so peculiar a creeping-root shoot has been affixed to 

 the |)lant figured in Flora Graca, 1.41.? If it be by error, II. repens is in 

 consequence a nonentity: nevertheless, shoulil such be the case, Ilermo- 

 dactylus longifolius SwI. and II. bispathaceus Swl. are without a doubt as 

 satisfactorily distinct as any two species need to be. 



The /Vis biflora of Linniciis is pu!)lished in Sweet's Flower-Garden for 

 July, t. 152.; where numerous technical details respecting it, which will 

 avail the studier of this genus, are presented : living plants of it are in the 

 Chelsea Botanic (ianlen, and in thegarilen of Mr. Sweet. /' ris reticulata 

 Biel). is figured in the Hot. Cab., July, t. 1829. Its leaves appear not to 

 attain a greater height than G in.; its flower is borne at 3 in. from the 

 ground, and is large and higidy beautiful. The .species is yet rare in 

 Britain.
