brown and leafless below, with many ascending pale-green, wide-spreading, leafy 
shoots a few inches long. Leaves pale green, sessile, alternate, ovate-oblong or 
obovate- oblong, very blunt, nearly terete, slightly flattened on face, J to ^ inch 
long by inch in breadth and thickness, set at right angles to the stem, bluntly 
prolonged below the point of insertion. Inflorescence borne on shoots similar 
to the barren ones, terminal, a few -flowered cyme of 2 or 3 usually simple, spreading, 
zigzag branches with or without a central flower ; flowers about 6 to 12 in all, each 
subtended by a bract resembling the leaves. Flowers yellow, f inch in diameter, 
the lower with pedicels shorter than the flowers, the upper sessile. Buds ovate, 
bluntly pointed, strongly ribbed. Sepals resembling the leaves, green, very 
fleshy, unequal, oblong-ovate, very blunt, bluntly spurred. Petals twice the 
smaller sepals, longer than the longest sepal, free, lanceolate, acute, often with a 
short apiculus, patent above, yellow, keeled. Stamens 10, spreading, a little 
shorter than the petals, filaments greenish yellow, tapering, anthers oblong, 
yellow. Scales very minute, \ as long as the carpels, oblong-cuneate, yellow. 
Carpels equalhng the stamens, at first erect, soon divergent, connate in lower half, 
greenish yellow, spreading in fruit, enclosed and equalled by the enlarging sepals. 
Flowers summer. Not hardy. 
Habitat. — Lanzarote, Canary Islands. 
The original description is inadequate : " Glabrum, tortuosum, 
foliis subovoideis, floribus breviter pedicellatis in cymam anfractam 
bipartitam terminalem scorpioideam bracteatam dispositis ; sepalis 
5, obtusis ; staminibus 10." It is stated to come near S. nudum 
but to " differ widely in habit," and attention is called to the " cymes 
remarkably wavy, almost recalling the arched internodes of Ranun- 
culus reptans L." As regards habit, S. nudum in Madeira forms small 
tangled shrubby masses, but in cultivation (e.g., old plants at Kew) 
it is herbaceous and nearly prostrate, with ascending branches, and 
is indistinguishable in growth-form from lancer ottense. In leaf nudum 
varies somewhat as regards shape and colour, and I find no character 
to separate the two plants. The best diagnostic features, as stated 
above lie in the sepals and scales. In my plants, too, the petals are 
more acute and of a clearer yellow colour. 
Dr. G. V. Perez, of Teneriffe, kindly had this plant searched for in 
Mr. Murray's station — in rupibus abruptis el Risco dictis in Lanza- 
rote " — and sent hving specimens. The spot where these plants were 
collected is described as south-west of the rock called La Chachara, 
which stands 500 metres north-west of the chapel of Las Nieves, 
Famara, Lanzarote.

This plant is in cultivation in Japan, at least in its var. senanense 
Makino, and deserves, therefore, a brief description in the present 
paper. It is a yellow-flowered species, with stems and leaves recalling 
those of 5. album. These points, in conjunction with its long, unequal, 
blunt, narrow sepals and stellate fruit, will separate it from any other 
species found in cultivation. Masters {loc. cit. p. 463) includes it in his
