MK. KIPPrST OX TWO SPECIES OF GENEXriiUS. 51 



4th series *, the latest, apparently, which had reached him when 

 writing his "Decas 6** generum Plantarum hucusque cognita- 

 rum," in which the name in question was first promulgated. He 

 there cites, as belonging to his G, macrostegia^ No. 40 of Drum- 

 mond's 4th collection; and with the single exception that the 

 leaves are not, for the- most part, opposite (a point, by the way, 

 in which these plants vary extremely, even on the same branch), 

 specimen so numbered corresponds perfectly with his de- 

 scription, as it also does with that of G. tulipifera, Hook., in the 

 ' Botanical Magazine.' 



The two recently introduced species being very closely allied, 

 and Turczaninow having had only one of them before him when 

 framing his definition, it can hardly be a matter of surprise that 

 niuch of that definition is equally applicable to both : still it 

 appears to me that, in addition to the very important character 

 already pointed out by Dr, Meisner, " calycis tubo basi decern- 

 costato" (while Sir William Hooker states that he can find only 

 Jive furrows in the lower part of the tube of his G. macrostegid)^ 

 there are one or two other points in which it accords better with 

 I the G, tulipifera of the * Botanical Magazine' than with the ma- 



crostegia of that work. For instance, the leaves are described aa 

 I Iroadlg linear; tlie capitula as cernuom; the bracts of the general 



involucre as obovate oittisey thrice as long as the flowers, " colore 

 purpureo plus minus tinctis," and the partial bracts as " basi roseis, 

 <ipice ativ-purjpureisi' while in the specimens of No. 98 of Drum- 



'inucro- 



mond's 5th series, unquestionably identical with the G. 

 ^tegia of the ' Botanical Magazine ' (for which Dr. Meisner pro- 

 poses the name G. Hooker iand), the leaves are much narrower, the 

 ^eads of flowers nutant rather than merely cemuous ; the bracts 

 of the involucre are elliptical, much less obtuse, and concolorous, 

 scarcely more than twice as long as the flowers (exclusive of the 

 style, which ill both species eventually becomes nearly as long as 

 the involucre), and the partial bracts show no indication of the 

 dark purple colour at their tips, which is so obvious in the dried 

 specimens of the broader-leaved plant, as well as in Mr. Fitch's 

 very characteristic figure of it. In this, which I take to be the 

 true G, macrostegia, the base of the calyx-tube appears to me rathiT 



• In Drummond's 5th series, both G. tulipifera and (?. macrostegia. Hook. 

 (a. HooJceriana, Meisn.), occur, in company ^^ith the two very ornamental and 

 ^eU-marked species just described by myself, whicli surely ^vouhl not have 

 l>een overiooked by Turczaninow, had that series, where the ' macrostegia ' of 

 the Bot. Mixg, first occurs, reached Moscow in time to admit of his msertmg 

 them in his paper.
