Cacalia. composite. 435 



2. C. reniformis {Muh\.) : stem sulcate-angled ; leaves petioled, green on 

 both sides, palmately veined (often slightly hairy on the veins beneath), re- 

 pandly angulate-toothed; the radical reniform ; the cauline flabelliform, di- 

 lated ; the teeth strongly mucronate; corymb compound, fastigiate. — Muhl.!

Rich damp woods, Pennsylvania! to North Carolina ! along the moun- 

 tains. Also in Illinois, Michaux (in a note under the following species), and 

 Indiana, Dr. Clapp! Aug.-Sept. — Stem 4-9feethigh. Leaves ample, di- 

 lated ; the radical often 2 feet wide ; the margin angulate-incised and repand- 

 toothed: the upper cauline either truncate, or more or less cuneate at the 

 base. Heads 5-flowered, as correctly described in Muhl. fl. Lancast. mss. ; 

 not manv-flowered, as stated by Willdenow. Scales of the involucre lance- 

 olate-oblong, obtuse. Receptacle slightly, or not at all produced in the 

 centre. 



3. C. at riplicifolia (hinn.) : stem terete, glaucous; leaves petioled, very 

 glaucous beneath, palmately veined, angulate-lobed or toothed (the teeth mu- 

 cronulate) ; the radical and lower deltoid-cordate or somewhat reniform ; the 

 upper rhomboid ; the uppermost cuneate at the base; corymb compound, 

 loose.— Linn. ! spec. 2. p. 835 ; Michx. ! fl. 2. p. 96 ; Pursh! fl. 2. p. 518 ;

Moist woodlands. Upper Canada to Georgia ! and Missouri! July-Sept. — 

 Stem 3-6 feet high. Radical and lower cauline leaves 4-6 inches long : the 

 lobes or teeth triangular, mostly acute. Scales of the involucre lanceolate- 

 oblong, obtuse. Receptacle produced in the centre into a lanceolate some- 

 what chaffy appendage, which is usually larger than the achenia, and 2-3- 

 cleft at the apex, as if composed of as many confluent paleae ; but is often 

 much shorter, or even inconspicuous. — Indian Plantain. 



4. C. diversifolia : stem striate-angled ; leaves petioled, green on both 

 sides, somewhat tripli-nerved, veiny ; the lower ovate, obtuse, slightly cor- 

 date, obtusely angulate-toothed or repand ; the upper 3-5-lobed, somewhat 

 hastate; corymb compound, loose. 



River swamps, Middle Florida, Dr. Chapman! May. — Plant 2-3 feet 

 high, not glaucous. Leaves nearly as large as in C. atriplicifolia ; the upper 

 on short but naked petioles ; the lateral lobes lanceolate, acute, entire, or 

 with one or two teeth. Heads, &c. as in the preceding. Receptacle slight- 

 ly produced in the centre. 



5. C. ovata (Walt.? Ell.) : stem terete; leaves glaucous beneath, tripli- 

 quintupli-nerved and veiny, ovate or oval, obtuse, entire or slightly and 

 irregularly repand-toothed; the lower and radical tapering into long, the 

 upper with short margined petioles; the uppermost sessile; corymb-compound 

 loose, fastigiate.— ( JFgZ«. Car. p. 196?) Ell.! sk. 2. p. 311 ; DC. I. c. 



Damp woods, western part of Georgia ! and Alabama! to Florida! and 

 Western Louisiana ! July-Aug. — Stem 3-4 feet high, quite terete, slightly 

 glaucous. Leaves rather veiny than nervose, pale and glaucous beneath ; 

 the radical (on very long petioles) and lower cauline with the lamina 5-8 

 inches long; the upper smaller and less petioled. Scales of the involucre 

 lanceolate-linear, rather obtuse. Receptacle with an obscure central projec- 

 tion, or none. — Walter's character " foliis nervosis utrinque vividibus " is more 

 applicable to the following species ; to which Elliott, if he had been acquainted 

 with that plant, would probably have applied the name. Having, however, 

 been appropriated, (perhaps correctly,) to the present specie.s, it should retain 

 the name. — Elliott calls the leaves obtuse in the characier, but acute in the 

 detailed description.
