the stigma. These are precisely the distinguishing features that 

 characterize Witheringia, but described in other words by M. 

 Dunal in p. 402 : this structure is indistinctly shown in L'Heri- 

 tier's figure, though better explained in his description. The 

 other features of M. DunaFs diagnosis, as respects the fornl of 

 the calyx, corolla, pistillura and fruit, will be found to agree 

 completely with those of Saracha, the species of which corre- 

 spond in habit with T/Heritier^s typical plant. It would have 

 been better for the sake of convenience to have retained the ge- 

 nus Saracha, now so long established, for the group of plants just 

 enumerated : this was maintained as long as a doubt hung over 

 the real nature of L'Heritier's plant ; but now that this doubt is 

 removed, we have no alternative but to follow the course de- 

 manded by the rules of science. 



Having thus removed from Saracha all its species, except 

 S. punctata, R. & P., which in reality is the original type of this 

 genus as instituted and figured in the Prodromus of the genera 

 of the ' Flora Peruviana' (p. 31. tab. 34), and which I formerly 

 separated from it in order to form the basis of a new genus 

 {Pcecilochroma) (Lond. Journ. Bot. vii. 353), we are now com- 

 pelled to retrace our steps, and re-establish Saracha for that 

 group of plants, so that the name of Pcecilochroma must conse- 

 quently be suppressed : the several species enumerated will now 

 stand as follows : — 



1 . Saracha punctata, R.^P., instead of Pcecilochroma punctatum,Mo5. [l. c.) 



2. frondosa, nob. ^ frondosum, nob. 



3. guttata, nob. =: guttatum, nob. 



4. maeulata, nob. = maculatum, nob. 



5. Lobbiana, nob. = Lobbianum, nob. 



6. Lindeniana, nob. = Lindenianum, nob. 



7- Quitoensis, nob. = Quitoense, nob. 



8. Boissieri, nob. = Boissieri, Dun. ^ Lyciople- 



sium Boissieri, Dun. 



9. Funkiana, nob. ^ Funkianum, Dun. 



10. Sellowiana, nob. = "Witheringia Sellowiana, Sendtn. 



Considering for the reasons before stated, that among the 

 several individuals included by M. Dunal in fVitheringia, the 

 typical species only belongs really to that genus, it becomes ne- 

 cessary to indicate the proper position of the remaining species 

 in the manner following : — 



2. Witheringia macrophylla, H. B. K. est Brachistus macrophyllus, nob. 



{hiij. op. iii. 263). 



3. Sellowiana, Sendt. =^ Saracha Sellowiana, nob. 



4. acuminata. Dun. = Brachistus acuminatus, nob. 



5. stramonifolia, H. B. K. = stramonifolius, nob. {huj. 



op. iii. 263). 



6. lanceolata. Dun. = verisimiliter Solani species. 



7- aspera, Spr. = potius Borraginea ut suspicat 



el. Dunal.
