of about 2 mm. long but not dense, divided to the middle into 

 three oblong-lanceolate lobes. 



Scapes 2-3 from the rosette, leafless, slender, studded with very 

 short glandular hairs, 17 mm. or less in height, and bearing at the 

 top, on pedicels about as long as the calyx, two flowers, or only 

 one, with a bract at base of pedicel. Sepals o. glabrous, ovate, 

 obtuse, with margin from middle upwards coarsely toothed or 

 crenate. about 1 mm. long, enlarging to 1-75 mm. after flowering ; 

 petals 0, white, oblong-ovate or -obovate, obtuse, 2 nam. or a little 

 more in length ; stamens 5 : styles 1, slender at base, clavate up- 

 wards, longer than sepals.

This species resembles D. pygmaa DC. in its minute size and 

 general aspect, but also more definitely in its leaves and stipules, 

 as weU as in the number and clavate character of the four styles. 

 It differs, however, in its otherwise o-merous symmetry, and in 

 the presence of more than one flower, and of bracts, on the scape. 

 These differences exclude it fromJPlanchons Sec. ii. Bryastrum, 

 containing D. pygmaa alone ; but while in the form of its or^ois 

 it shows a close similarity to that species, its differences relate 

 rather to the numbers of parts in the floral organs, showing 

 therein an approach to perfect isomerism, which is less common 

 in the genus than a variability in the number of parts, not only 

 in individual plants of a species, but also between one species 

 and another. D. occidental is would best form a subsection of 

 Bryastrum, agreeing with D. pygmaa in its four styles and in the 

 leaf lamina, bur differing in its otherwise 5-merous symmetry.

An erect plant, reaching 31 cm. in height, somewhat woody 

 towards the base, with numerous flexuose leafy branches from the 

 base upwards, clothed with a grey woolly tomentum. Leaves 

 alternate, somewhat rigid, narrow-lanceolate, induphcate, sud- 

 denly contracted below to a stem-clasping base and somewhat 

 decurrent, spreading above the base, then incurved to a stiff 

 hooked point, beyond which is often to be seen a thin hyaline 

 yellow expansion, midrib and two lateral veins prominent on the 

 under surface, maximtmfi length 5 cm., breadth OS cm. at base, but 

 mostly smaller and diminishing upwards to flower-heads. 



Flower-spikes terminal, single, ovoid to cylindric-obovoid, 

 yellow, the largest 22 x 12 cm., subtended by a circle of leafy 

 bracts, seldom exceeding the width of the spike, and showing the 

 hooked point and scarious appendage observed in the leaves. 

 Florets two in each partial head, the two innermost involucnd 

 bracts hyaline with an opaque midrib, flat, spathulate and nar- 

 rower than the outer, with a short incurved hyaline yellowish 

 lamina, bracts and florets 3— i mm. long ; corolla 5-lobed, expand- 

 ing towards the top, slender below, but swollen at base over the
