52 A FLORA OF GIBRALTAR AND THE NEIGHBOURHOOD 



'■"^Centrantlms ruber DC. Eocky places, probably not native, 

 but quite naturalised; 4-6. I. Above Devil's Gap, flowers 

 usually white ! Parson's Lodge ! 



C. Calcitrapa DC. Eocks, old walls and stony places ; fre- 

 quent? 4-6. Very near next, but usually shorter and more 

 slender, cymes more compact, and corolla tube only as long as 

 achene. I. About Willis's ! III. i. Cork Wood Crags ! ii. Pal- 

 mones Playazo ! I think it occurs in many other places, but I 

 had difficulty in distinguishing it from next. 



C. viacrosipJion Boiss. Similar places, and in deep sand ; 

 much commoner; 3-7. Usually much stouter, corolla tube 3 

 times as long as achene. I. ! III. ! 



Fedia Langei Pom. Cultivated fields, &c. ; abundant ; 1-5. 

 Known from next by oblong-linear fruit. The relative lengths of 

 corolla tube are not reliable, and the species are indistinguishable 

 in flower. I believe both are equally common I. ! II. ! III. ! 



F. graciliflora Fisch. k Mey. {F. CormtcojncB Gaertn. ?). 

 Similar places ; abundant ; 1-5. Fruit suborbicular, more or less 

 inflated. Perez Lara gives the synonymy cited, but Pomel shows 

 that there are difl"erences {Vide Deb. Fl. pp. 98-99). 1. ! III. ! 



Valerianella microcarpa Lois. Dry fields and grassy places ; 

 rather rare ; 2-4. A slender annual, fruit the smallest of our 

 species, less than \ line long, calyx limb very small, obtuse. 

 III. i. Path above Bonel's Farm ! West slopes of Queen of 

 Spain's Chair ! Cork Woods ! 



V. truncata Betcke. Similar places ; rare ; 3-5. Shorter 

 than last, corymb closer, fruit rather larger, calyx limb reticulate, 

 apiculate, as long and as broad as fruit. III. i. Eiverside above 

 Almoraima ! 



t V. carinata Lois. Similar places ; rare ; 3-5. Flowers in 

 dense globose heads, fruit If by 1;^ lines, prominently ribbed, 

 crown hardly distinct from body. III. i. By Soto Gordo ! 



V. coronataT>C Sandy cultivated or fallow fields ; rare; 4-5. 

 A stout annual, very like next, but calyx campanulate, glabrous 

 within. Kelaart wrongly makes them synonymous. III. i. Near 

 San Eoque, Wk. ii. Near Algeciras, Rev. 



V. discoklea Lois. Similar places ; frequent ; 4-5. Calyx 

 subrotate, tomentose within. I. Moorish Wall! Near Michael's! 

 Engineer Eoad ! III. i. Near Campamento Cemetery ! San 

 Eoque, especially on north side ! Cork Wood Ci'ags ! ii. Near 

 Algeciras Cemetery ! iii. Near Guadacorte ! 



DIPSACE.E. 



Dipsacus sylvestris Mill. Damp grassy places ; common ; 

 6-7. Central scales of inflorescence often long, forming a coma 

 as in D. ferox. III. ! 



\CepJialaria syriaca Schrad. Dry fields; I'are, probably 

 casual; 6-7. Annual, 6-18 in. high, heads small non-radiant, 

 pale blue or lilac, pales and involucre longly mucronate. III. i. 

 San Eoque, K. Perez Lara wrongly cites the station as 

 Gibraltar.
