correspond exactly in their margins with those of P. cylindraceus. 

 In the copious "addenda " to the Flora no reference is made to the 

 identity of G. lusiostachyiun with P. cylindraceus, although this is 

 clearly indicated by Mr. Hiern. 



The synonymy of the plant under Plectranthus is : 

 Plectranthus cylindraceus Hochst. in Schimp. iter Abvss. Sect. 2, 

 1113 ! Benth. in DC. Prodr. xii. 60 (1848) ; Baker in Fl. Trop. 

 Afr. V. 414 (Dec. 1900). Germanea cijlindracea Hiern, Welw. 

 Cat. i. 861 (Aug. 1900). 



Geniosporum lasiostachyum Briquet in Engl. Bot. Jahrb. xix. 164 

 (1894) ; Baker in Fl. Trop. Afr. v. 351 (June, 1900). 



Plectranthus moschosmuides Baker in Fl. Trop. Afr. v. 414 (Dec. 

 1900). 



The omission under Solenostemon ccymoides of the synonym 

 Coleus ? africanm (Benth. herb. 54) is not of much importance, but 

 it might have been cited, especially as Don's specimens, on which 

 Bentham's plant was estabUshed, are in the National Herbarium. 

 Coleus orbicularis Baker (/. c. p. 437) is, as noted by Mr. Hiern 

 (Journ. Bot. 1901, 108) the same as Solenostemon niveus Hiern, 

 Welw. Cat. i. 864, the full description of which is transcribed on 

 p. 526 of the Flora, without any indication that the plant had 

 already been described from the same Welwitsch number earlier in 

 in the book. " Coleus rupestris Hochst. in Schimp. PI. Abyss. 

 No. 2172" is cited (p. 409) as the type of Plectranthus rupestris 

 Baker, and later (p. 430) as a synonym of C. barbatus Benth. var. 

 Schimperi Baker {C. Schimperi Vatke). According to Briquet (Bull. 

 Herb. Boiss. ii. 131) the two plants are identical. This author 

 retams the name C. rupestris Hochst., and says: " Le nom donn6 

 par Hochstetter ayant ete publie dans un exsiccata regulierement 

 numerote, a etiquettes autographiees, a une priorite incontestable 

 sur celui de Vatke, au terme des Lois de la Nomenclature, art. 42." 

 This position seems, as M. Briquet says, *' incontestable," but it is 

 not accepted by Mr. Jackson, in whose Index Hochstetter's names 

 are ignored. Nor does Mr. Baker always cite them : e. g. I cannot 

 find in the African Flora Acrocephnlus abyssiiiicus Hochst. in 

 Schimp. PI. Abyss, ed. ii. no. 2046. There is also an unnecessary 

 variety in the citation of the plants ; in many cases the names are 

 quoted thus : " Thymus serrulatus Hochst. ; Benth. in DC. Prod. xii. 

 203 " ; in others thus : Micromeria longijiora Hochst. in Schimp. 

 PL Abyss. Exsicc. no. 2192 " : the latter is manifestly the correct 

 method. If, however, the principle be acted upon, it will result in 

 changes of accepted names : Mr. Baker, for example, retains Salvia 

 Schimperi Benth. in DC. Prod. xii. 282 [1848] , and cites (as does 

 Bentham) S. hypoleuca Hochst. in Schimp. PI Abyss, exsicc. [sect. 3] 

 no. 1916 [1844] . Bentham seems to have set this aside in favour 

 of his own S. hypoleuca (Prodr. xii. 279), but if the Schimper label 

 constitutes publication Hochstetter's name must be restored, and 

 S. hypoleuca Benth. will require another trivial designation.
