1. HOTT6NIA, L. Featherfoil. (In memory oi Prof . Peter ffoftoti oi 

 Ltyden.) — Rooting, ofteB floating, glabrous, branching, with air-bearing fistulous 

 stems and peduncles. Sepals linear. Corolla white. Filaments short. Stigma 

 capitate. Capsule membranaceous. Flowers dimorphous in the manner of 

 Primula in the European species, the earlier cleistogamous in the following. 



'H. inflata, Ell. Leafy stems and especially the intemodes of the emersed flowering ones 

 or peduncles much inflated (the latter often as tliick as fingers) . proper leave^ dissected 

 into long and numerous filiform divisions ; whorled bracts linear or spatulate, entire, a 

 quarter inch long, mostly exceeding the pedicels : corolla only a hne or two long, with 

 short lobes as well as tube, not equalling tlie calyx; the tliroat open: style short. — Sk. 

 i. 201 ; Xutt. Gen. 1. 120. H- palustris, Pursh, &c., not L. — Shallow water, Massachusetts 

 to Louisiana : fl. summer. 



2. DODECATHEON, L. Shootixg Stae, Ajier. Cowslip. (Fan- 

 ciful name, from dade/.a and Osoi, twelve gods ; the .specific name of the original 

 and, as we suppose, the only species commemorates Dr. Richard Mead, and was 

 given as generic by Catesby.) — Flowers few or numerous in an umbel, termi- 

 nating a naked scape, in late spring or summer, handsome, resembling the solitary 

 flower of Cyclamen : corolla from pink-purple to white. Calyx erect in fruit, 

 enclosing the lu\Aer pai't of the ovoid or fusiform crustaceous capsule. 



D. Meadia, L. Perennial herb, with fibrous roots : leaves crowded on a thickish crown, 

 generally spatulate-oblong or oblauceolate and entire or nearly so, sometimes repand, 

 obtuse, below tapering into more or less of a margined petiole, in the typical or Atlantic 

 form 3 to 9 inches long; vriiile the scape is from a span to 2 feet high; and the flowers 

 from few to many in the umbel : bracts of the inyolucre linear or subulate, small : pedicels 

 slender and nodding with the flowers, erect in fruit. (Flower rarely 4-merous.) — Mtadia, 

 Catesb. Car. iii. t. 1 ; Ehret, PI. Sel. t. 12. D. Meadia &, D. integrifolium, Jlichx. Fl. i. 123. 

 D. irdegrifoUum, Hf>i)k. Bot. Mag. t. 3022. Dianthus Carolinianus,'\\'a\.t. Car. 140. — The 

 Atlantic plant, in moist and shaded grounds, Michigan and Penn., and tlirough the upper 

 country to Georgia, thence to Arkansas and Texas. ^Yestwa^d the species extends to 

 Califorrua and Behring Straits, under very various forms and varieties, which may be 

 generally oIa>sified as follows (after Bot. Calif, i. 467) ; the Pacific forms generally having 

 shorter or blunter anthers than the Atlantic or typical D. Meadia, L. 



Var. brevif olium. Leaves from obovate or ovate to broadly spatulate, half inch to 



an inch and a halt long, abruptly contracted into a petiole ; scape 3 to 12 inches high, few- 

 manj'-flowered : capsule seldom exceeding the minutely glandular calyx. — D. elli/iticum, 

 Xutt. ex Durand, PI. Pratt, in .Tour. Acad. Pliilad. n. ser. ii. 9-5. D. integrifoliiim. Benth. PI. 

 Hartw. 322. — Common in W. California. Forms nearly answering to tliis, or larger-leaved, 

 occur in Arkansas, Kentucky, and Pennsylvania. 



■=■ Var. lancifolium. Leaves oblauceolate or elongated-spatulate, 3 to 10 inches long, 

 the short margined petiole included, quite entire, mucronate : pedicels and calyx commonly 

 minutely glandular ; lobes of the latter lanceolate or triangular-lanceolate, nearly equalling 

 the short-ovoid capsule. — D. JajTraiji of the EngUsh gardens. — Wet mountain meadows 

 of California, especially in the Sierra Xerada. 



Var. alpinmn. Like diminutive forms of the preceding, with shorter as well as 

 smaller leaves (half inch to an inch and a half long) : scape 2 to 10 inches long, 1—4- 

 flowered ; pedicels and calyx glabrous. — High Sierra Xevada to the Rocky Mountains. 



Var. macrocarpum. A large and stout form, emulating the common Atlantic 

 plant : leaves thickish (rarely laciniate-toothed), tapering gradually into a rather short 

 petiole : capsule oblong or even fusiform, 6 to 9 Unes long, about double the length of the 

 narrow calyx-lobes. — "W. California to Alaska. 



Var. frigidum. Leaves from obovate to oblong, very obtuse, mostly entire, an inch 



or two in length, ^vith short or long and slender petiole : scape a span or two high, few- 

 several-flowered : lobes of the calyx longer than the tube, from broadly lanceolate to 

 almost ovate, shorter than the oblong capsule. — Hook. Bot. Mag. t. 5371 ; "V\'ats. Bot.
