and the Pyrenees, in 1825. 3^ 



profession. The garden, which has neither enjoyed the advan- 

 tages of a zealous botanist nor of a grant of money to defray the 

 expences, has been almost allowed to go to wreck during the po- 

 litical dissensions ; the wages even of the gardener not having been 

 paid for two or three years. Scarcely does there remain five hun- 

 dred species ; but among these are the Schiniis molle, Varronia 

 alnifbUa, CcBsalpinia sappan, Acacia longifolia and horrida, Phy~ 

 satis aristata, and some other species cultivated in our hot-houses, 

 scarcely above the rank of shrubs, but which here in the open 

 air attained a considerable magnitude *. We saw here the 

 Amalia aerisincola : it has hung out of the window, we were 

 informed, for fifteen or twenty years, and still bears its flowers 

 every summer. We advised Dr Bahi to put it in earth for a; 

 season, as by that means it would become much stronger, and 



* In this garden we met with Helianthemum croceum of Dunal and Lagas- 

 ca. As this species is much confused with //. glaucum^ perhaps the following 

 observations, made, in December 1825, with Professor De Gandolle's permis- 

 sion, on his herbarium, may be of use. 1. In this herbarium there is a spe- 

 cimen of H. glaucum from Lagasca, with the note " Cistus glaucus^ Cav. Ic 3, 

 t. 261, absque dubio, collatum cum specimine originali," presented to M. De- 

 candolle in 1819 : This specimen has the calyx almost woolly; the hairs are 

 white, and not very rigid, and are distributed almost entirely on the some- 

 what prominent nerves : this was recognised by Dunal as his var. «. — 2. The 

 var. /3. of Dunal differs solely by the hairs on the nerves of the calyx being 

 very rigid, or rather hispid. In both these varieties the leaves are well de- 

 scribed in the " Prodromus." — 3. H. croceum^ Desf. Two specimens of this 

 exist in Professor De Gandolle's horbarium, both given by Desfontaines, and 

 these shew that the figure in the " Flora Atlantica" is by no means correct. 

 The calyx is in reality furnished with long hispid hairs on the very promi- 

 nent nerves ; moreover, the whole calyx and the hairs are of a brownish-yel- 

 low colour : the upper leaves are broadly lanceolate, and somewhat acute : 

 the fruit is pubescent, as in H. glaucum. The H. croceum^ Desf. I therefore 

 consider a mere variety of H. glaucum^ Cav. As a variety, however, it is dis- 

 tinguished from the two mentioned by Dunal, by the colour of the calyx and 

 the hairs of it, as well as by the yellowish hue of the whole plant, and the 

 croceorus petals. — 4. H. croceum^ Dun. in De Gandolle's Prodromus, is another 

 question. Though pretty well represented by the figure in the " Flora At- 

 lantica," it neitlier agrees with the above mentioned specimen given by Des- 

 fontaines of his H. croceum^ nor with his description. The calyx is, as Dunal 

 describes it, hoary and pubescent, but not hispid : it is the H. croceum given 

 by Lagasca to De GandoUe, and is apparently, from the localities attached, 

 extremely common in the South of Spain. The specimens we gathered in the 

 garden of Barcelona had the petals yellow, and not of a saffron colour, as the 

 name imports.
