ciliate; petals triangular. June. I. scattered, often crowded, 

 oblong-elliptical, very obtuse ; margins recurved, strongly ciliate- 

 denticulate. h. lit. to 2ft. 1864. A bushy shrub. SYN. Gene- 

 tyUisfimbriata. (B. M. 5468.) 



D. Hookerlana (Hooker's).* This species much resembles 

 D. macrogtegia, but is usually smaller, more slender, and less 

 twiggy. SYN. Genttyllit Hookeriana. (B. M. 4860, under the 

 name of Genetylli* macrostegia.)

 otherwise smooth ; petals rather narrow, concave, with a deep- 

 coloured spot at the top. May. I. mostly opposite, linear or 

 lanceolate, obtuse ; margins revolute. h. 1ft. SYN. Hedaroma 

 thymoides.

FTG. 616. FLOWERING BRANCH OF DARWINIA MACROSTEGIA. 



D. macrostegia (large-involucred).* Tulip-bearing Myrtle, fl. 

 rather numerous ; involucre campanulate, nearly IJin. long ; the 

 petal-like inner bracts broadly obovate, pale yellow, streaked with 

 red, entire ; petals white. June. 2 scattered, elliptic-oblong or 

 slightly cuneate, obtuse, iin. to Jin. long; margins recurved, 

 entire, h. 2ft. to 3ft 1854. SYNS. Genetyllis tuUpifera (B. M. 

 4858), G. macrostegia, Hedaroma tulipiferum. See Fig. 616. 



D. pinifolia (Pine-leaved). This species closely resembles 

 D. fascicularix in habit, foliage, and inflorescence, but with 

 a different calyx and staminodia. SYN. Hedaroma pinifolium. 



D. purpurea (purple), fl. numerous, in dense, hemispherical 

 heads ; involucral bracts numerous, more or less coloured, imbri- 

 cate, but somewhat spreading, rather longer than the flowers ; 

 calyx about two lines long, the adnate part flve-ribbed at the 

 base, the upper half encircled by five or six rings of glandular 

 papillae. I. scattered, crowded, and almost imbricate, linear, 

 obtuse. Erect, much-branched shrub. SYNS. Genetyllis purpurea, 

 Polyzone purpurea. 



D. taxif olia (Yew-leaved). fl. white, at the ends of the branchlets ; 

 calyx prominently five-ribbed, the adnate part slightly rugose 

 between the ribs ; lobes small, scale-like ; petals ovate. June. 

 I. mostly opposite, linear-falcate, triquetrous or laterally com- 

 pressed, acute, iin. to Jin. long, almost petiolate. h. 1ft. to 3ft. 

 1824. A straggling or decumbent shrub. 



D. thymoides (Thyme-like), fl. sessile, four to eight together, 

 in terminal heads, tha outer bracts sometimes slightly exceeding 



allied to Nolina. Flowers dicecions, in dense panicles; 

 flower-stems sometimes 10t. or 12ft. in height. Leaves 

 crowded, linear, gracefully drooping. They thrive in a 

 compost of two parts loam, one peat, and one sand. 

 Perfect drainage and a plentiful supply of water during 

 the summer months, are important cultural items. In- 

 creased by seed. Dasylirions form admirable plants for 

 sub-tropical gardening, or for conservatory and indoor 

 ition. 



D. acrotrichnm (hair-tipped).* fl. white ; panicle dense, cylin- 

 drical, 4ft. to 5ft. long. I. densely rosulate, recurved, linear, 2ft. to 

 3ft. long, less than Iin. broad, with a long fibrous tuft at apex ; 

 marginal spines sharp, yellowish. Trunk stout, simple, h. 6ft. 

 to 10ft. Mexico, 1851. SYN. D. gracile. (B. M. 5030.) 



D. a. brevifolium (short-leaved). I. shorter than those of the 

 type, rarely more than 2ft. in length, not becoming pendulous. 



D. glaucophyllum (milky-green-leaved).* fl. white; panicles 

 narrow, 3ft. to 4ft. long ; peduncles elongated ; flower-stem 

 10ft. to 12ft. high. I. dense, 2ft. to 3ft. long, about Jin. broad, 

 glaucous ; margin armed with small teeth, h. 12ft. Mexico, 

 1846. SYN. D. glaucum. (B. M. 5041.) The variety latifolium 

 has broader leaves, and is more robust in growth than the type. 



D. glaucum (grey). A synonym of D. glaucophyllum.
