either as broad or a little broader than, or only half the height ; 
always naked. Ach. of ray unequally triquetrous incurved and 
convex at the back, the angles winged, crowned with a dimidiate 
secund 4-tootlied coriaceous border ; of disk small abortive 
linear-oblong compressed winged at the ventral margin, crowned 
as in the ray, but gradually less distinctly inwards. 
In drying mostly inodorous, yet sometimes in sea-cliff ex- 
amples approaching /3, exhaling a tine hay-like fragrance. 
The union of all the separate cymes of each branch, whether 
many or few-fld., into one immense close cyme, often 3 or 4 ft. 
or even more in diam. and covering the whole bush, renders this 
pi. in fl. one of the most striking objects of the ravine or moun- 
tain flora of Mad., forming broad masses of a dazzling white- 
ness conspicuous from afar on rocky cliffs and precipices. 
3. succulenta, dwarfish thickly bushy, branches crowded close 
short ; 1. stiff fleshy less distinctly lobed, the lobes and teeth 
more or less obtuse, cymes reduced to 1-2 or 3 fl. — Chr.

Louren^’o abundant on the Ilheo dos Embarcadores and I. de

and approaching a. March- June. — A mere depauperated ma- 
ritime var., and, as such, stiffly and thickly fleshy or succulent 
in all its parts, with a densely leafy bushy dwarfish habit, and 
only 1-3 terminal fl. to each branch. A low shr. 12-18 in. 
high, covering the ground in dense bushy leafy masses. L. 
crowded 2-3 in. long (including petiole), |-f in. broad, smaller 
or shorter and less deeply (not halfway down) or distinctly 
lobed or divided than in «, with the lobes shorter and more 
evenly or finely but obtusely toothed rather than serrate, and 
more or less stiffly rigid thick and fleshy. In extreme states 
they are more properly doubly inciso-toothed than pinnati- 
lobate. Fl. mostly solitary or 2-3 only, rather larger or at 
least much coarser and thicker than in a ; heads swollen hard 
and fleshy, on stouter stiller ped., in fr. very turgid large and 
rigid with the disk hemispherical and the recept. hemispheri- 
cally conoidal solid within and woody. Ligules 15-20, about 
1 in. long, 3 lines broad, spreading horizontally, finally re- 
curved or reflexed ; disk f in. in diam. Ach. of ray unequally 
triquetrous, incurved and convex at the back, the 2 side an- 
gles broadly winged, the ventral narrowly winged or simply 
keeled, the wings or angles produced into an auriculate or di- 
midiate obliquely secund irregularly toothed coriaceo-mem- 
branous crown or border: ach. of disk compressedly subquadr- 
angular and strongly ribbed, with a single broad ventral 
wing only, very finely reticulato-granulate or shagreened as if
