a. fruticosus alhus and B. rosmfloms coronarius. The double 

 form of II. fruticosus (R. hcllidijlorus Koch, Dendrol. i, p. 292), 

 is weU known as having pink flowers, with very numerous, narrow 

 petals (Gard. Chron. 1878, x, pp. 240, 241, fig. 43). 



Buhus uhnifoli'us, Schott, was described in 1818, being based 

 on materials collected at Gibraltar. It may be interesting to 

 repeat the short description, as the work is rather inaccessible. 

 " Buhus uhnifoUus. Fruticosus aculeatus, foliis quinatis terna- 

 tisque foliolis acuminatis, infra tomentosus, pedicellis calycibusque 

 tomentosis, inermibus. Floribus amoene rosaceis. A Bubo 

 fruticoso nostro, certe diversus. Hab. in montosis Gibraltarise." 

 This is quite clearly identical wdth the widely diffused plant which 

 we have been considering. According to Major WoUey Dod, who 

 remarks, " I can only distinguish one fairly constant species," it 

 is common and often abundant in bushy places at Gibraltar. 



We now come to the name B. discolor, under which the plant 

 is frequently knowm, and as which it was figured by Boswell Syme, 

 the figure being identical with the one given in the earlier edition 

 of the work as B. fruticosus, L. B. discolor was originally 

 described and figured by Weihe and Nees in 1824, from materials 

 collected near Bonn, and the authors cite (Eub. Germ. v. p. 46) 

 as a synonym, " Buhus fruticosi varietates, quae plurimi auctorum 

 laudant ' floribus roseis onatos.' " As to this B. discolor of Weihe 

 and Nees, Focke says that only the figures c, d, and e belong to 

 B. discolor as now understood, the greater part of the plate and 

 some of the original specimens belonging to B. liedycarpus, Focke. 

 The discrepancy is indeed obvious on comparison of the plate and 

 specimens. Moreover, Weihe and Nees had already figured a 

 white-petaled Eubus ^^ B. fruticosus, L. (Eub. Germ. fasc. i, p. 24, 

 t. 7), which is cited by Focke as B. candicans, Weihe. Babington 

 accepted the name B. discolor for the common British plant, and 

 observes (Brit. Eubi, p. 102), "The B. fruticosus of the Linn. 

 Herb, consists of bits of this and of several other species " ; this, 

 however, is not borne out by an examination of the original sheet. 



B. rusticanus, Merc, appeared in 1861, the author remarking: 

 " Cette espece si commune chez nous et dans les contrees meri- 

 dionales de la France, en Italie et en Dalmatie, en Algerie, etc., 

 n'est pas decrite dans les Eubi germanici de W. et N. parceque 

 probablement elle disparait dans les contrees septentrionales de 

 I'Allemagne. . . . Je dois observer que le nom de discolor est 

 appliqu6 encore a d'autres especes dans I'Herbarium normale de 

 Fries, dans la monographic d'Arrhenius, etc. Je I'ai trouve dans 

 di verses collections sous les noms de dalmaticus, d'argejiteus. 

 C'est bien certainement en partie le Buhus fruticosus de la Flore 

 de De Candolle, de la Flora Helvetique de Gaudin, etc." The 

 name was extended to the British plant by Focke (Journ. Bot. 

 1890, p. 129), and was afterwards used by Eogers. 



The characters of the species are well described by Eogers. 

 " Later in coming into bloom (by two or three weeks) than the 

 vast majority of species, and usually among the last to abstain 

 from flowering in the late autumn, or even up to mid-winter.
