very finely adpressed puberulons, appearing glabrous, often red- 

 dish. III. i. Cornfield by the Cagancha, near San Roque ! 



S. 'portensis L. Sand-dunes ; rare ; 6-8. Very slender, much 

 branched from the base, leaves very narrow-linear, flowers in 

 dichotomous cymes, calyx elongate, not contracted at mouth in 

 fruit, carpophore long, seeds flat on face and back. III. ii. Near 

 Palmones Elver, Bev. 



S. inaperta L. Sandy hills ; rare ; 5-6. Eesembling last, but 

 minutely pubescent, less branched from base, fruit calyx much 

 shorter, carpophore shorter, seeds channelled on back. III. i. Foot 

 of San Eoque and of S. Carbonera, D. 



S. stricta L. Dry, gravelly, or sandy places; rare; 5-6. Very 

 viscid, leafy nearly to top, panicle branching, fruit calyx con- 

 tracted at mouth, truncate at base, ribs narrowly winged, petals 

 bright rose. Closely resembles S. viuscijJula L., which has wing- 

 less calyx ribs. III. i. Near San Eoque, Ball. ii. Algeciras 

 Station ! 



■\S. nutans L. (S. longicilia Otth.). Dry hills; rare; 4-6. 

 Perennial, flowers nodding, carpophore decidedly shorter than 

 capsule. III. ii. Upper slopes beyond Waterfall, an unusually 

 broad-leaved form ! S. de Palma, Bev. Leaves of apparently the 

 same species near summit of Frayle ridge ! 



\S. mellifera B. & E. Stony and rocky places ; rare ; 4-6. 

 Near S. italica, but flowers greenish yellow, and calyx only 4-6 

 lines long, leaves broader. III. i. Alcadeza Crags ! 



\S. italica Pers. Dry banks and rocky ground; rare; 4-6. 

 Perennial, flowers erect in a viscid panicle, carpophore as long as 

 capsule, petals white, calyx 6-7 lines long. III. i. Eocky ravines 

 of San Eoque and open places in Cork Woods, Boiss. 



S. moUissima Sibth. & Sm. (S. vclutina Pourr.). Eocky fissures 

 and precipices ; rare ; 4-6. Very softly tomentose, petals white, 

 often red on back, calyx glandular-pubescent, veins anastomosing. 

 I. North and east precipices, Boiss., Wk., etc. By Mediterranean 

 Eoad and west side of Eock, K. 



^ S. gibraltarica Hoiss. Similar situations; rare; 4-6. Differs 

 in shorter pubescence, pale violet flowers, calyx without veins, 

 viscid, as well as upper part of panicle. Perhaps a variety of last, 

 confined to the Rock and North Africa. I. Inaccessible parts on 

 east side, Boiss., Wk., etc. By Mediterranean Eoad, K. I have 

 searched for this in vain over Catalan Bay, where much of the 

 vegetation has been removed from the foot of the precipice in 

 connection with the water catchments. 



[5. conica L. Eecorded by Lagasca from the Eock; probably 

 an error.] 



S. inflata Sm. Eough bushy, or cultivated ground and 

 roadsides; rather frequent; 3-5. Debeaux only records var. 

 angjcstifoUa DC, which I have not seen. I. ! III. ! 



•j >S'. commutata Guss. Similar places ; rare ? 3-5. Like last, 

 but leaves bi'oader, often subcordate, more fleshy, pedicels longer, 

 calyx more inflated, seeds finely granulated, not tuberculate.
