2. G. maritima. Raf. Marsh Gerardia. 
St. angular; vs. linear, fleshy, short, rather obtuse; fls. stalked; cal. 
truncate; wpper segmenis of the corolia tringed.—Q@ Native of salt marshes, 
Mass. to N. J., also shores of L. Mich. Houghton. This species resembles the 
foregoing, of which Pursh describes it as a variety. It is a smaller plant 6— 
12’ in height, and with smaller flowers. The leaves are shorter and thicker. 
The calyx segments are cut square off, not acute as in the preceding. Corolla 
purple. Flower-stalks axillary and terminal. July—Sept. 
3. G. TENUIFOLIA. Vahl. Smail-flowered Purple Gerardia. 
Branching ; lvs. linear; ped. axillary, longer than the flowers; cal. teeth 
short, acute.—() A slender and delicate species, usually very branching, but 
often simple, in fields and woods, U.S. Stem 6—12’ high. Leaves about an 
inch long, very narrow (scarcely a line in width), entire, rough, obtuse, often 
coiled. Flowers opposite, axillary, on slender stalks an inch or more in length. 
Corolla purple, spotted within, the border much spreading, smooth and nearly 
equal. Calyx teeth short and acute. Aug. Sept. 
4. G. aspErRA. Doug. Rough Gerardia. 
St. a little branched; dvs. long and narrowly linear, floral ones exceeding 
| the calyces ; ped. twice longer than the calyx; calyx teeth lanceolate, acute, about 
as long as the tube; cor. glabrous.—{() Illinois, Buckley in DC., Prod. x. 518. 
Peduncles sometimes but little exceeding the calyx, sometimes twice as long. 
Flowers as large as those of G. purpurea, to which species this is perhaps too 
nearly allied. 
5. G. seTacea. Walt. 
Branches slender, roughish; dvs. setaceous, roughish; fls. few; ped. alter- 
nate and opposite, very long; cal. teeth short and setaceous ; caps. ovate, larger 
than the calyx.—@ Penn.? to Car. Nuttall? Scarcely darkens in drying. 
6. G. Sxinneriina. Wood. (G. aphylla. Benth. in part, not Nutt.) 
Scabrous, pale green; st. erect, sparingly branched, slender, 4 angles mar- 
gined ; lvs. remote, linear, acute at each end, the floral ones 2 or 3 times shorter 
than the very long peduncles; cal. teeth very short, glandular-acute ; cor. infun- 
dibuliform-campanulate, lobes short, spreading; caps. roundish-ovoid, scarcely 
exceeding the calyx.—@ Barrens, Ia.! Plant 12—18’ high, the stem and few 
branches quite slender and rough on the slightly winged angles. Leaves (8—12" 
by 4—3’’) much shorter than the internodes, margin slightly revolute. Pedun- 
cles 1—12’ long, erect. Corolla (5—6’) glabrous, light purple or rose-color. 
Capsule loculicidal, about 30-seeded. Jl. Aug. 
Obs.—I detected this delicate species in July, 1846,in Greene Co., Ia., on land belonging to Dr. A. G. 
Skinner, whose zeal in botanical pursuits deserves more than this slight notice. It does not turn black in 
drying. 
23. OTOPHYLLA. Benth. 
Gr. ovs (oros), ear, GvAXov, leaf; alluding to the auriculate leaves. 
Calyx deeply 5-parted, sepals leafy, unequal; cor. tube enlarged 
upwards, lobes broad, entire; sta. didynamous, the upper pair with 
smaller abortive anthers! caps. subglobose, many-seeded.— Erect, harry 
herbs with opposite leaves. F'ls. axillary, solitary, subsessile. 
O. Micuavuxu. Benth. (Gerardia auriculata. Michx.) Michaux’s Gerardia. 
Scabrous-hirsute, subsimple; /vs. ovate-lanceolate, lower entire, upper 
mostly auriculate-lobed; fis. sessile-—( Penn. to Il., Rev. E. Jenny! in prai- 
ries and low grounds. A rough, rigid plant, 9—18’ high. Leaves (1- 14/ by 
$—+') entire on the margin, sessile; floral ones with an oblong-lanceolate lobe 
each side at base. Flowers alternate or mostly opposite, calyx deeply cleft, 
corolla purple or rarely white, pubescent, dilated at the mouth, 9—12” long. 
Aug. Sept. 
24. DASYSTOMA. Raf. 
Gr. dacvs, hairy, cronxa, mouth; alluding to the character of the corolla. 
Calyx campanulate, halt 5-cleft, imbricate in sestivation ; cor. tube
