 ridfres but microsconicslly and densely pepulpte, as seen under a 

 very strons lens, uniformly grass-green, not at all glaucous and 

 not PeTlucid-dotted. Pedicel g inch long, slightly compressed, 

 2-edpred, 3 lines broad and 2 lines thick, smooth, green. ^al3rx

 lines long and 3 lines broad, ovnte, obtuse, two of them acutely 

 keeled end v/lth a blunt dorsal noint, and two vjith v/hite membranous 

 margins. Corolla 2-2-1 inches in diameter, expanding in the morn-

 closing about 7 p.m.; petals in 1-2 series, ascending-spreading, 

 10-15 lines long, 1-1 1/3 line broad, cuneately linear, obtuse and 

 often denticulate at the apex, bright yellow, not shining. Stamens

 to view, 4 lines long; filaments and anthers yellow, the former 

 not bearded. Stigmas 8, l-i--2 lines Ion?, radiately spreading, plu-

Described and ^ig. 208 (see p. 449) prepared from a living 

 T)lent received from "^r. R. Merioth. ■'■his species bears some resem- 

 blance to G, praeningue, but its leaves are of firmer substance, 

 not pellucid-dotted, and its flowers are pedicellate. 



11. G. concavum, K. 3. Cp. (Fig. ?09, p. 449).— Rootstock 

 bearing a number of crowded growths at the ton, on very sbort divi- 

 sions scarcely amounting to branches. , Leaves 2-3 pairs to a grov/th, 

 ascending un'bil old, then spreading, li-S-^ inches long, 4-9 lines 

 broad and 3-5 lines thick at the base, narrow, somehwhat seniterete 

 and slifThtly tanering to an acute or blunt apex, usually somewhat 

 curved or slightly sigmoid, one leaf or a pair concave and the 

 other convex on the face, the concave leaf usually keeled on the 

 back and often slightly tivisted; soft and oulpy, smooth, glrbrous, 

 frass-green, the older leaves (but not the^^younger) distinctly pel- 

 lucid-dotted when held againt the light, edicel about 9 lines 

 long and 3 lines thick, some^-hat semiterete, being slightly flat- 

 tened on one side and somewhat 2 edged, ^alyx in mature bud 6-7 

 lines in diameter, 4-lobed; lobes 4-6 lines long, more or less 

 keeled and three of the keels minutely ciliate, the outer lobes 

 acute and the inner obtuse, v/ith a dorsal point and broad membranous 

 marerins. Corolla 2-2i inches in diameter, opening in the morning, 

 even in dull, sunless weather at a temperature belov; 60*-" Fphr. 

 Petals numerous, free, or nearly so, in tvm distinct series, 12-16 

 lines long and 1-1 J line broad, linear, obtuse and scarcely toothed 

 at the anex, bright clear yellov/ on both sides, not shining. -Sta- 

 mens numerous, collected into a central mass, 6-7 lines long, quite 

 concealing the stigmas, yellov;. -^tigmas 10, radiating, l-t line 

 Ions', Plumose, yellowish. 



^escribed and ^ig. 209 prepared from a living plant sent to 

 me bv I'lrs, L. Bolus. This species must be nearly related to G, 

 angustum, . He^A'. ^ but according to ^%worth*s description of the letter 

 species, it differs by its pedicellate flowers, much smaller corolla 

 end -free or nearly free petals. ™he lon^ and narrow leaves (which, 

 when received, were only 4-6 lines broad, but have now become 

 broader and thicker) concave on the upper side of the longerof each 

 pair, distinguishes this from all others knovm to me.
