 description, he stRte,s thetS-- "^-r. -"^iton does not notice tljls__ 

 plant in his Hortus ^^v;ensis, Mt I have seen it very fine at i^ew." 

 And in his Syponsis Planterum Succulertaruin (IPI2) , under M. gd- 

 scendens, he writes: "If the next species but three (i.e., ^^i. 

 longum) is not the M. folio linguiformi lingiore of Dillenius, 

 this me.y he it, hut if so he had delineated the leaves too long," 

 Later, (Rev. ^1. 3ucc. n. 96) he states that 1^^, adscendens is 

 "probabl^r a variety of ^'I. longum." "^his seems to indicate that he 

 ■WPS not very clear as to v;hpt ^.I. lonfru'^- was. -^^ll the above are 

 described as having the pedicel "longer than the calyx" or "to 

 inches long or more." But under 1^, longum in his ^ev. ^i. Succ, 

 p. 96, he describes the flov/ers as subsessile, '^o that this would 

 arpcar to be some different species. Evidently there is some con- 

 fusion, for under M, longum var. flaccidum on p. 96 of ^ev. Pi, 

 Succ, ^aworth ouotes both "^olckamer's figure mentioned above the 

 figure in the Botanical ^'"agazJne, t, 1866, ps representing the 

 same species. But Volckamer's nlant has erect or ascendinglong 

 lepves and nedicellate flov/ers end is no Soubt a bad figure of G. 

 lonmam, while Bot. ^--ag., t. 1866, represents a plant with short 

 leaves tressed down close to the ground and sessile flov/ers and 

 belongs to ^. denres_sum_. 



Var. hamatxim, K.E.br. (^^ig. 222). — '-hrowths pressed upon the 

 ground, ^eaves not sr^reading but directed forwards in the direction 

 of growth, 2-3v inches long, 7-lC lines broad and one leaf of e 

 pair 3-4 lines thick and the other 4-5 lines thick, strap-shaped, 

 straight or slightly upcurved edgev/ays, the smaller leaf flat of 

 faintly convex on the face, convex on the back and obtuse at the 

 spex, and the larger leaf of each pair with the face scmev/hat ob- 

 liouely concave, from being raised all along the lower margin into 

 a strong and soiajewhat scute ridge, obliquely and bluntly keeled on 

 the back, and with a very large and conspicuous obliquely incurved 

 hook at the apex; both leaves have a pustule or sv/elling at the 

 base; surface smooth end shining, and the surface-cells neither 

 raised nor depressed as seen v/ith a strong lens, light green. Ped- 

 icels 3-7 lines long, slightly compressed and slightly 2-edged, o- 

 Zi- lines broad. Calyx ( a dried flov/er only seen) subequplly 4- 

 lobed; lobes ebout 4-5 lines long and 3|- lines broad, ovate, two 

 of them acutely keeled. Corolla about 2^ inches in diameter accor- 

 ding to the figure; '^etals numerous, in 2 series, free or nearly so, 

 apparently 10-12 lines long and £ line broad, cuneately linear, 

 obtuse yellov7. Ste-niens very numerous, about 3 lines long, yellov;. 

 Stigmas 8-9, about 1 line long, spreading, rlumose. Cppsule when 

 closed 7-8 lines and vrhen exrianded 12-15 lines in diameter, shortly 

 and broadly obconic, flattish, vdth 8-9 gaping ridges on the top, 

 and with 8-9 valves and cells; brown outside, pallid within; valves 

 reflexed; panding keels distant, subparallel, with acute and micro- 

 sconically denticulate edges, pale ochreous-brown or honey-coloured, 

 tinned vT;^th ? lineer or oblong-linear membrane; ce^ls acutely roofed 

 and the opening nearly closed by a very large v/hite tubercle. 

 Seeds -J- line in diameter, comnressed-globose, with a small inflexed 

 nipple, smooth, pale brovm.
