5. BREWERIA. 



Breweria, E. Br. Prod. 487 ; Benth. et Hook. Gen. PL ii. 876. 



A genus of about twenty-four species varying greatly in habit, distributed 

 over the warmer parts of both the old and new worlds. Three of the Socotran 

 species are endemic, and the fourth is essentially a plant of the desert plains of 

 north-west Africa, and south-west Asia. 



1. B. (Seddera) latifolia, Benth. et Hook. Gen. PI. ii. 877. 



Seddera latifolia, Hochst. in Flora 1844, Beil. 7, t. 5, ff. B, C. ; Choisy in DC. Prod. ix. 440 ; 



Boiss. Flor. Orient, iv. 114. 

 Cressa latifolia, T. Anders, in Journ. Linn. Soc. v. (I860), Suppl. 25 (syn. plur. excl.). 



Soeotra. On the plains. Not uncommon. B.C.S. nn. 17, 727. Schweinf. 

 n. 352. 



Distrib. Abyssinia, south-west Asia. 



A characteristic desert plant presenting a very various appearance according 

 to its locality of growth. Frequently a hard dwarf undershrub with small 

 leaves, in other places developing long twigs with larger leaves. 



It is quite a distinct plant from B. evolvuloides, Choisy (Convolv. Or. 112, 

 and in DC. Prod. ix. 439), with which T. Anderson considered it conspecific. 



2. B. (Seddera) pedunculata, Balf. fil. in Proc. Roy. Soc. Edin. xii. (1883), 



83. 



Suffruticosa virgata incana pubescente-tomentosa ; foliis oblongis subsessilibus ; fioribus valide 

 pedunculitis in axillis solitariis ; calyce corolla breviore ; ovario hirto ; stylis 2. 



Suffrutex virgatus incanus pubescente-tomentosus a basi ramosus ramis strictis divaricatis. 

 Folia remota pauca subsessilia oblonga obtusa v. apiculata \-\ poll, longa £ poll, lata, 

 superiora multo minora, dense pubescentia. Flores pedunculati in axillis foliorum 

 superiorum solitarii et racemos longos laxos formantes ; pedunculi breves validi 

 adscendentes bracteis longiores ad medium v. supra articulati bracteolisque 2 minutis 

 suffulti. Sepala subeequalia | poll, longa ovata subacuta extus pubescentia post 

 anthesin patentia. Corolla in superiore dimidio exserta extus pilosa. Staminum filamenta 

 tenuia. Ovarium hirtum ; styli 2 corolla breviores, stigmatibus capitatis. Capsula 

 £ poll. diam. supra pilosa calyce £ longior. Semina glabra minute punctulata. 



Soeotra. On the plains. B.C.S. n. 158. 



Distrib. Endemic. 



A form with some resemblance to the foregoing species, but very Convolv- 

 uloid in aspect. Its two styles with capitate stigmas technically exclude it 

 from Convolvulus, and its four ovules shut it out of Evolvulus. In Breweria 

 it falls into the section Seddera, and is readily distinguished in the section by 

 its stout floral pedicels and its virgate habit. 



3. B. (Seddera) glomerata, Balf. fil. in Proc. Roy. Soc. Edin. xii. (1883), 

 83.
