83 TOLUIFERA PEREIRA 



cannot consider this as a sufficient reason for departing from the 

 acknowledged rule in nomenclature, and have therefore employed 

 the earlier name, as does also Prof. Baillon. 



In Klotzsch's paper above quoted 8 species of Myroxylon are 

 given, which it seems more correct to reduce to a considerably 

 less number. Baillon, indeed, with much reason, now considers the 

 present to be but a form of T. Balsamum, L. (Myroxylon Toluifera, 

 H. B. K.), but we follow Hanbury in keeping them distinct, not 

 having had the opportunity of examining good specimens of the 

 latter. 



The name " Myrospermum SonsonatenseyPeveira/' used by Oersted 

 and other writers for this plant, was never given by Pereira, who 

 in his original account, referred to below, merely called the tree 

 " Myrospermum of Sonsonate " for the purpose of distinction from 

 other species. 



Young plants of this tree may be seen in botanic gardens, but 

 they have not flowered in this country. 



Myroxylon peruiferum, Linn, f., long supposed to be the source 

 of Balsam of Peru (as indicated by its name), is a distinct species. 

 As there has been so much confusion in the nomenclature of plants 

 of this genus it will be desirable to give some references to 

 figures and descriptions. It has many synonyms and has been 

 figured several times : Syn. Myrospermum peruiferum, DC. ; 

 M. pedicellatuni, Lam. ; M. erythroxylon, Allemao ; Myroxylum 

 pubescens, H. B. K. ? ; Myroxylon pedicellatum, Klotzsch. M. 

 robinieefolium, Klotzsch ? Figures. Nees t. 321 (poor) ; Lambert, 

 111. Gen. Cinchona t. i, figs. 1 and 2, cop. in Steph. and Ch. t. 102 

 (flowers only) ; Hayne. xiv, t. 11 ; Berg and Sch., t. 29 e. This tree 

 is a native of Ecuador, Peru, and Brazil, and yields a fragrant 

 balsam not unlike Balsam of Tolu, called at Rio " Olea vermelho."
