2. M. Faulo-Gulielmi (after H.R.S. Prince Paul William, of 

 Wurtenburg), F. v. M. Fragm. i. 86 ; Benth. Fl. Aitstr. vi. 251. Stems seidomi 

 if ever at all raised above the ground, but, like all this genus, forming a deep yam-like- 

 rhizome or stem beneath the surface. Leaves about 6 to 20, including the short- 

 portion (or petiole) without pinnse, about 2 feet long, more or less spirally- 

 twisted ; petioles 4 to Sin. long and 3 or 4 lines broad, the base broader with thin 

 scarious edges and very woolly, the upper surface as well as the rhachis flat, but- 

 rounded on the under surface. Pinn^ very numerous, often 109 on each side of 

 the flat rhachis, narrow-linear, falcate, with from 3 to 5 rather prominent ribs on 

 the under side, 4 to Sin. long, 1 to 1^ line broad, the apex often with 2 or & 

 short teeth, the white callous base often prominent. Scapes woolly, surrounded! 

 at the base with linear woolly prophylla of about lin. long. Male cones conical,. 

 3 or 4in. long and about l|in. diameter in the centre. Scales about -|in. wide- 

 and Jin. deep, the lower ones with a very small central point, the upper one* 

 with points 2 or 3 lines long and slightly recurved and pungent ; anthers smalL 

 Female cones conical, glabrous or with a few short silky hairs, about Sin. long 

 and 3 broad at the base. Scales about 1 to l^in. broad and fin. deep, with a 

 very prominent transverse ridge which forms in the centre an erect spine of about 

 lin. long and not more than 1 line broad. Seeds angular, lin. diameter, covered! 

 by a fleshy golden-yellow integument. — Fnaphalartos, Paulo-GuUehiii, F. v. M.

3. IVI. spiralis (spiral), Miq. 2'Ioywcir. Cycad. 86 t. 4, 5; Benth. Fl. Aitstr. 

 vi. 251. Stems seldom if ever formed above the surface but forming long 

 underground stems or rhizomes, the crown of leaves few, or on old plants ini 

 favoured localities sometimes as many as 50. Leaves more or less spirally twisted 

 2 to 4 or at times 5ft. long, while young covered by a loose wool, the broad 

 expanded base bearing a dense coating of a mouse-coloured wool, the petiole or 

 portion of the rhachis without pinnae nearly terete and from 1 to l-|ft. long. 

 Pinnse erecto-patent, glossy and flexuose, 30 to SO on each side of the rhachis,. 

 with seldom any abbreviated ones at the base, 6 to 13in. long and 2 to 5 lines broad,, 

 the underside prominently striate, the white callosity at the base very prominent^ 

 the apex pungent, only toothed on very young plants. Scapes about 1ft. high,, 

 slightly woolly. Male cones cylindrical. Gin. or more long, l|in. in diameter, the- 

 central spine of scale reduced to a pungent point in the lower part of cone, but- 

 lengthening out in the upper portions to nearly ^in. long. Anthers small and 

 very numerous. Female cones more or less woolly, 6 to 8in. long and about S 

 to 3iin. in diameter. Scales about fin. deep and l-|-in. wide, the transverse lines- 

 forming a sharp ridge running into an erect, lanceolate, flat, central spine of from 

 J to 2in. in length. Seeds covered with a reddish integument about lin. long 

 and nearly as broad. — Xamia spiralis, E. Br. Prod ; Encephalartos spiralis, Lehm.
