cincto, antheris hastatis acutis apice subglabris tamen cohserentibus, 

 stylo brevi stigmate umbrae id i-formi apiculato iiuculis facillime separa- 

 bilibus subtrigonis extus semi sphsericis adprsse hispidis lateribus planis 

 I foveolatis. 



Proximum videtur H. bicolori, differ t floribus sessilibus nee pedicel- 

 latis et ab omni subgencre forma stigmatis. 



Scrophularineoe. 



Linaria, probably L. Halava, but I have lost the specimens. 



Anticharis arabica, Benth. in D. C. p. 347. 



My specimens differ only in the leaves being ovate, or lanceolate, not 

 linear-oblong, as there described. 



Campylanthus junceus. — Glaber, bracteis ciliatis, fauce corollse 

 tubo inferiori intus pilosis antheris l-Iocularibus muticis. 



Suffrutex ramosus subaphyllus, folia parva subulata crassiuscule 

 caduca. Racemi longi terminales. Corollae limbi segmenta 2-superiora 

 paullo minora sestivatione intima ; filamenta mucronata cum connectivo 

 sub-apice articulata, antherae in alabastro etiam 1-loculares loculo aperto. 

 Stylus complanato-dilatatus apice glanduloso, crenulato, stigmate unila- 

 terali. Semina uniformia ala membranacea omnino circumdata. 



This curious looking shrub differs from the generic character as at 

 present limited, in the form of the anther, but it seems otherwise so 

 fully to correspond in habit with Campylanthus as to merit a place in 

 the genus. Although Anticharis and Doradanthera appear to differ 

 exactly as this plant from Campylanthus. 



Acanthacece. 



Acanthus Imbricatus. — Prostratus, ramis tentibus albis, foliis bre- 

 vi petiolatis ellipticis, spinuloso-dentatis obtusis acutisve suprascabris 

 subtus incanis, bracteis numerosis imbricatis ovatis acuminatis spinosis 

 nervosis exterioribus lepidotis, interioribus pubescentibus velutinis ner- 

 vis pilosis, calyce piloso apice spinuloso, corolla extus deorsim adpresse 

 puberula intus divaricatim pilosa, labio inferiorc 3-lobo cseruleo, stami- 

 nibus inferioribus longioribus supra connectivo longe cornuta, antheris 

 per imparia oppositis dense ciliatis. Capsulam ct semina non vidi. 



I have named this provisionally, having no means of ascertaining whe- 

 ther it has been already described or not, pending the publication pi 

 the family in DeCandollcs' Prodromus.
