1. Berberis Madei^ensis, Lowe. — B. fruticosa spinis tripartitis, Mils 

 simplicibus subspathulatis oblongo-lanceolatis obtusiusculis basi at- 

 tenuatis subcoriaceis rigidulis reticulatis submarginatia integerrimis, 

 ramulis aurantiacis costatis v. striatis, racemis erecto-patentibus ab- 

 breviatis subpaucifloris, floribus globosis. 



Hab. In rupibus excelsis convallium Maderse, ad altitudinem 5000 



ped., rariss. 



This, the only indigenous Madeiran Barberry, most resembles B. 

 Creiica, L., which may however be at once distinguished by its low, 

 dwarfish, stunted, densely prickly habit, thick, short branches, and 



small leaves. 



I revert to my original name of B. Maderensis for this plant, disco- 

 vered by me first in 1838 ; that of ^. lycioides, by which 1 have more 

 lately for some years spoken of it, trenching too closely upon B, Lycium 



of Eoyle. 



2. Cheiranthus arhuscula^ Lowe, — C. fruticulosus pygmseus dumosus 

 foliosus, caule erecto nano apice capitato-ramoso, ramis abbreviatis 

 plerumque congesto-glomeratis, foliis linearibus apicem versus sub- 

 dilatatis acutis integerrimis incants scabris adpresse strigosis, floribus 



lilacinis, siliq[uis strictis arete erectis. 

 Hab. Abundanter in rupibus montium Pico Branco et P. de Conselho, 



Portus Sancti. 



Preserves, when cultivated in England, its peculiar, low, stunted 



habit. Flowers and pods large. 



This is the plant erroneously referred to under the name of Chei- 

 ranthus tenuifoUuSy Hent., in 'Frimitics Fauna et Flora Madera et 

 Portus Sancii,\ p. 57, as the favounte haunt of ffelta: cheiranthicola, 

 Lowe. The true C. tenuifolius, Hent., is a perfectly distinct Madeiran 

 species, not found at all in Porto Santo, and very rare or local even in 



Madeira. 



3. Spergularia fallax, Lowe.— S. glabra, foliis linearl-subulatis fas- 

 ciculato-verticUlatis mutlcis obtusis subteretibus basin versus supra 

 planiusculis subcanaliculatis, pediceUis defloratis refractis. sepalis
