58 A FLORA OF GIBRALTAR AND THE NEIGHBOURHOOD 



fleshy, peduncles stouter, bracts more numerous. I. Western 

 slopes, Wk. 



S. erraticus Hevtol. Similar places ; common? 6-10. Near *S. 

 aquaticus Huds., but with lax paniculate, not corymbose inflore- 

 scence, leaves much less divided than in last. II. ! ? III. i. and ii. ! 



S. gallicus Chaix. Sand-dunes and light soil; locally common ; 

 1-5. A rayed annual, inflorescence corymbose, leaves all pinna- 

 tisect. The type (var. laxiflorus DC.) has an external calycule of 

 short phyllaries. I. At and beyond Governor's Cottage ! 



Var. exsquameus DC. has no calycule. III. i. and iii. Sand- 

 dunes at Linea and Palmones ! Dautez says type and var. are 

 indiscriminately mixed. I have found type only on the Rock, and 

 only var. in Spain.

 rather tall, stem leaves entire, broadly amplexicaul, upper some- 

 times inciso-dentate, anthodes few and large. I. ? Dasoi. This 

 collector's records are not reliable.

 annual, often much branched, leaves inciso-dentate, not lobed, 

 corymb few-headed, heads larger than those of S. gallicus. 

 I. Sandy grassy places on w^est side of Rock, D. 



S. minutus DC. f var. gibraltaricus Wk. Shady rocky places ; 

 rare ; 5-6. Heads few, rather large, on long subradical pedun- 

 cles, radical leaves dentate, cauline simply pinnate, lobes linear, 

 sometimes dentate. I. Lein.l Both sides of Rock, Wk., Boiss., 

 (&c. Kelaart indicates the Governor's Cottage as its habitat, 

 where I have repeatedly searched in vain for it. 



S. lividus L. var. major G. & G. Shady bushy ground ; rather 

 rare ; 2-6. I. Lem. ! East slopes, Wk., D. III. i. Summit of 

 Chair ! Cork Woods ! ii. Railside near Algeciras ! Waterfall ! 



S. vulgaris L. Fields, roadsides and waste places ; very 

 common; 1-12, but chiefly 12-3. I.! II.! III.! Reaches 

 highest summits ! 



Calendula arvensis L. Open sandy, stony and grassy places, 

 rarely in mountains or woods ; abundant; 11-5. Strictly annual,

 next. Outer fruits erect or incurved, lateral wings broad, spines 

 on back many, large, in two rows, usually a spur inside at base. 

 It varies with deep orange flowers. I. ! II. ! III. ! A field full of 

 the orange-flowered form at Magazine Hill ! 



Var. malacitana P. L. Flowers half the size, ligules often not 

 longer than phyllaries, fruit larger and more spinose. Debeaux 

 admits the var. only, though it is much rarer than type, at least in 

 good forms. I. Below Devil's Gap ! III. Rather frequent to 

 Carnero Point I 



G. stellata Cav. Rocky and stony slopes ; locally common ; 

 3-5. Stout, much more straggling, probably always annual, but 

 often becoming woody at base, flowers as large as next, outer 

 fruits stellately spreading, muricate, not spiny on back, wingless 

 or nearly so, no spur on face at base. I.! III. i. Alcadeza
