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, i to ^ inch 

 long by j\ 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 equaUing 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, 

 fohis subovoideis, floribus breviter pedicellatis in cymam anfractam 

 bipartitam terminalem scorpioideam bracteatam dispositis ; sepalis 

 5, obtusis ; staminibus 10." It is stated to come near 5. 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, 5. 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 otiense. 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 He 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 TeneriSe, kindly had this plant searched for in 

 Mr. Murray's station — " in rupibus abruptis el Risco dictis in Lanza- 

 rote " — and sent living 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 recaUing 

 those of S. 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
