++ Pedicels usually exceeding the corolla: woolly anthers cuspidate at base. 
7. G. setacea Walt. Mostly scabrous, at least the setaceous-filiform leaves: inflo- 
rescence more or less paniculate; pedicels ascending, 1 to 3 cm. long: calyx-teeth subu- 
late, from minute to ¢ length of tube: corolla 18 to 25 mm. long, often pubescent out- 
side, the margins of the lobes thickly lanose-ciliate: anther-cells short-aristate.— 
Pine-barrens, etc., extending at least as far west as Gillespie County (Jermy). 
8. G. strictiflora Benth. Obscurely scabrous, excessively paniculate-branched, 
rigid, 3dm. or more high: leaves filiform-linear passing on the branches into subu- 
late; these erect and 6 to 12mm. long, rigid, shorter than the erect or ascending (12 
to 18 mm.) pedicels: calyx-teeth short but conspicuous, subulate, very acute: corolla 
12mm. long or more: anther-cells aristulate at base.—Eastern and southern Texas. 
20. CASTILLEIA Mutis. (PAINTED CUP.) 
Herbs, with alternate entire or cut-lobed leaves (the floral ones usually 
dilated, colored, and more showy than the yellow or purplish spiked 
flowers), tubular flattened calyx cleft at summit on anterior and usualyl 
posterior side also (divisions entire or 2-lobed), corolla-tube included in 
calyx (its upper lip, galea, long and narrow, arched and keeled, flattened 
laterally, inclosing the 4 unequal stamens; lower lip short, 3-lobed), 
and oblong-linear unequal anther-cells (outer fixed by the middle, inner 
pendulous). 
* Annuals or some biennials with fibrous roots: floral leaves or bracts dilated: calyx 
equally cleft before and behind; galea shorter than corolla-tube, little surpassing calyx, 
much exceeding short lower lip. 
1. C. coccinea Spreng. Rosulate radical leaves mostly entire, obovate or oblong; 
cauline and bracts laciniate or 3 to 5-cleft; the middle lobe of latter dilated: calyx- 
lobes quadrate-oblong.—Low sandy ground, extending from the Atlantic States into 
Texas. 
2. C. indivisa Engelm. Leaves lanceolate-linear and entire, or sometimes with 
2 or 3 slender lateral lobes: bracts and calyx-lobes obovate-dilated, bright red.— 
Southern and western Texas. 
** Perennials. 
+ Calyx about equally cleft before and behind: floral leaves and bracts more or less 
dilated and petaloid colored (red or crimson, varying to yellowish or whitish). 
++ Herbage white-woolly throughout: leaves linear and entire: bracts 3-parted: corolla 
almost ineluded, 14 to 18 mm. long, slender; the narrow galea longer than tube; lip 
very short. 
3. C.lanata Grav. Apparently herbaceous to base, branching, white with ap- 
pressed arachnoid wool: leaves 2.5 to 5 cm. long: galea longer than tube: flowers 
somewhat scattered in the spike.—Southwestern Texas. 
++ ++ Tomentulose or cinereous-puberulent, or stem only lanate-tomentose: bracts, etc., 
conspicuously petaloid: corolla more exserted, 25 mm. long or more; galea shorter 
than tube. 
= Lip very short; its lobes not longer than the more or less callous saccate portion, 
4. C. integra Gray. Stem rather stout, tomentose: leaves cinereous-tomentulose, 
linear, 3.5 to 7.5 cm. long, 2 to 6 mm. wide, entire: bracts of the short spike linear 
or obovate-oblong, red or rose-color, entire or sometimes incised: corolla about 3 
cm. long; galea rather broad; lip strongly tri-callous, its lobes very short.—Dry 
grounds, western Texas. 
5. C. Lindheimeri Gray. Branched, cinereous-puberulent or the stem tomentu- 
lose: leaves narrowly linear, entire or sparingly laciniate, or the upper 3 to 5-cleft, 
as are the bracts of the dense spike; these mostly petaloid and dilated, from brick-
