160 ME. J. BALL ON THE BOTAlS^r 



non Poh\ {sec, DC. 7. c). Most of the specimens ia herbaria 

 labelled B, mavginata, DC, and B, glutmosa^ Pers., should be 

 referred to this plant, which should retain Colla's older name, 

 unless they should all be considered as forms of _B. </lutmosa, 

 Pcrs., as to which I am somewhat doubtful. B. confcrtifolia 

 has a rather wide range on the western side of S. America from 

 Central Chili to Peru. A specimen in Kew Herbarium from 

 Santiago del Estero in Argentaria, and named by Gri.sebach B. 

 ghitinosa^ Pers., is certainly different from B, confer tlfolia^ the 

 nervation of the leaves being quite dissimilar. 



ExcELTA CA>'EscEis*s, Cav,^ var. TOiiE]S'TOSA = E. tomentosa, 

 Walj). (Phil. 218). As I have already remarked, all the specimens 

 of Encelia from South America seen by me appear to be referable 

 to E, canescens. The present variety is very near to A. Gray's 

 E.farinosa from California. 



Skytalanthtts acutus, Walp. et Meijen {Phil, 228). This 

 small bush is rather abundant in some spots near Caldcra, but its 

 area seems to be extremely limited, not having been hitherto 

 found except in this immediate neighbourhood, thougli too con- 

 spicuous to be overlooked. The authors of the 'Genera Plantarum' 

 have maintained the name SJcytaiiilius as originally written by 

 Meycn, though the discoverer of the species subsequently cor- 

 rected the name so as to conform to its correct etymology. 



CoLDEMA LiTOBALis, Phil, FL Atac. No. 248. Philippi found 

 this species on the sands of the sea-shore near Caldera; I found 

 it in some abundance on the sandy flats about a mile inland, with 

 cream-coloured flowers having much the appearance of a Fran- 

 Icenia. It is certainly distinct from C. dichotoma^ having the 

 calyx-segments longer and divergent \vhen in fruit, while in C 

 dicliotoma they arc adpressed and usually close together over the 

 fruit. The nutlets in the Caldera plant are subsplierical and 

 granulated on the surface, while in C. dicliotoma they are smaller, 

 ovoid, nearly black and polished. The leaves also are different, 

 being distinctly petiolate in (7. litoralis^ and in C. dicliotoma 

 sessile but tapering to the base. 



Chenopodiacearum, sp.? Too imperfect. Even the genus 

 uncertain. 



Stipa toetuosa, Besx). {Phil, 392). This species appears to 

 be rare and confined to Northern Chili.
