P. Chamlsso't, Ar. Bemi. (Mauritius, Rodrigues). — Under 

 P. crisjjiis, L., the author lemarks, " P. Chamis-soi, Ar. Benn.. 

 must be ranked under the Lucentes." I do not know what 

 induced this remark, but I suppose Graebner's placing it 

 next crispiis, as I distinctl}^ state it has nothing to do 

 with crispus (Jour. Botany, xlii, 74, 1904). Yet the strange 

 thing is that tlie earHest specimens from Mauritius, 

 " Roxburgh, 1819,"' are named " crisj^iwi," and the latest, 

 " H. H. Johnston, 1889," are also named " crispus." And I 

 believe this is the plant named crispus in Baker's Fl. 

 Mauritius, 392 (1877), and also the plant sent by Bory de 

 St. Vincent to Chamisso (before 1814), but to which he 

 put no name in Linnaea, ii (1827), 200, wliich he puts 

 under lucens (from the " L'ile de France "). Thus there 

 must be something that suggests crispus to those who 

 have gathered but not studied the plant. The author has 

 only seen Johnston's specimens. On present knowledge 

 this well-marked species is confined to tlie three Mascarene 

 islands. It might perhaps have been expected in Mada- 

 gascar, as they have another " Lucentes " species between 

 them, l.(\ P. vaginans, Bojer, of which there is a type- 

 specimen in the Vienna herbarium. To me it stands apart, 

 just as P. Rohhinsii, Oakes, does in North America. 



P. lithuanicus, Gorski (Lithuania). — The author remarks. 

 " I have also examined specimens from Lithuania labelled 

 'P. salicifolius' which have been identical (identified?) 

 with another hybrid, P. IWiuanicus, Gorski, but the}* 

 cannot be regarded as authentic." So he places salicifolius 

 under nitens /? suhperfoliatus (Hagst.), /'. praelongifolius, 

 Tis., and lithuanicus he puts under decipiens ^ brevifolius, 

 Hagst. I have a specimen of P. lithuanicus, Gorski, from 

 the author himself, and it is labelled "P. llihuaiiicus, S. B. 

 Gorski profi", 1847, E fiumine Vilia, Lithuania." It is 

 absolutely idcsntical with Wolfgang's salicifolius. In fact, 

 it is more like Wolfgang's own specimen I have, than those 

 in De Candolle's herbarium from Besser. In neither case 

 do I consider them the hybrids he places them under. 



P. Gaudichaudii, C. et S. — The author notes that 

 Graebner, in Das Pflanzenreich, Heft 31, 79 (1907), remarks, 

 " Specimena originalia desunt." This is certainl}' so regard- 

 ing Chamisso 's, but there is an ori^jinal one in the lierbariura
