Ilysanthes. SCROPHULAPJACE.E. 283 



filiform, with minutely capitate tip : capsule oblong-conical, acuminate, about the 

 length of the 2-bracteolate calyx : seeds oval or short-oblong : corolla white or 

 purplish-tinged. 



Gr. pilosa, Michx. Stem a foot or two high from an apparently annual root : leaves 

 ovate or ovate-lanceolate, sparingly and acutely denticulate, closely sessile by a broad 

 base : corolla 3 or 4 lines long, little exceeding the calyx ; the tube oblong. — Fl. i. 7 ; 

 Pursh, 1. c. ; Benth. 1. c. ; Chapm. Fl. 293. G. Peruviana, Walt. 1. c, not L. — New Jer- 

 sey to Florida and Texas. 

 G. Slibulata, Baldw. A span high from a ligneous perennial root, very leafy : leaves 

 linear-lanceolate, obtuse, entire, with revolute margins, rigid: corolla half inch long, 

 somewhat salverform ; its slender tube nearly thrice the length of the calyx, marcescent 

 and recurving in age. — Benth. in DC. 1. c. ; Chapm. 1. c. Sophronanthe hispida, Benth. in 

 Lindl. Introd. Nat. Syst. ed. 2, 445. — Coast of Florida, in sandy pine barrens. 

 6. megalocXrpa, Ell. Sk. i. 16, is a factitious species, established by Elliott wholly upon 

 Pursh's G. acuminata, which is based upon Walter's character, but evidently confused with 

 some other plant. 



G. micraxtha, Nutt. in Am. Jour. Sci. v. 287 (E. Florida, Ware), is characterized as hav- 

 ing an erect angulate stem, a foot high, lanceolate and serrate acute leaves attenuate at 

 base, peduncles shorter than the leaves, ebracteolate calyx 4-parted, and stamens 4. Prob- 

 ably Scoparia dulcis. 



18. ILYSANTHES, Raf. ("Ilvg, mud, and uvOrj, blossom.) — Low and 

 rather small flowered annuals, or chiefly so, glabrous, branching ; with opposite 

 undivided leaves, all but the lowest sessile, and flowers on filiform ebracteolate 

 pedicels, which are either axillary or by reduction of the leaves racemose or 

 paniculate, in fruit usually refracted. Calyx-lobes narrow. Corolla violet or 

 bluish, or partly white. Sterile filaments in ours glandular with a glabrous lateral 

 lobe. Flowering all summer, in wet soil. — Raf. Ann. Nat. 1820, 13; Benth. in 

 DC. Prodr. x. 418. 



I. grandiflora, Benth. 1. c. Stems creeping at base, leafy throughout : leaves roundish, 

 entire, thickish : peduncles all much surpassing the leaves: corolla (3 or 4 lines long) 

 about thrice the length of the calyx : lobe of sterile filaments rather long and borne 

 below the middle. — Lindernia grandiflora, Nutt. Gen. ii. 43. — Eastern Georgia and Florida, 

 Nuttall, Garber, &c. 



I. gratioloid.es, Benth. 1. c. Diffusely spreading from the base, or at first Bimple and 

 erect, leafy : leaves ovate or oblong, often slightly and acutely few-toothed ; the later 

 ones reduced to bracts : corolla (3 lines long) hardly twice, the length of the calyx : lobe 

 of sterile filaments short: capsule ovoid, equalling the 'calyx. — Capraria gratioloides, L. 

 Spec. ed. 2, 876. Gratiola anagaUidea, Michx. Fl. i. 5. G. dilalata, Muhl. Cat. G. atten- 

 uata, Spreng. Syst. i. 39. G. tetragona, Ell. Sk. i. 15 ? Lindernia pijxidaria, Pursh, Fl. ii. 

 419, not Allioni. L. dilatata & L. attenuata, Muhl. in Ell. Sk. i. 16; Bart. Fl. Am. Sept. i. 

 31. Herpestis callitrichoides, HBK. Ilysanthes riparia, Raf. 1. c. — Canada to Florida and 

 Texas; also Oregon and California. (S. Am., E. Asia, and nat. in W. Eu.) 



I. refracta, Benth. 1. u. Stems a span or two high, erect from a rosulate tuft of spatu- 

 late-oblong or obovate radical leaves (of an inch or less in length), filiform, below bearing 

 one or two pairs of small and oblong or oblong-linear entire or obscurely serrate leaves, 

 and above only linear-subulate bracts, which are many times shorter than the almost 

 capillary racemose pedicels : corolla narrow (3 to 6 lines long), four times the length of 

 the calyx : capsule oblong, from one half to twice longer than the calyx : root perhaps 

 biennial. — Lindernia refracta, Ell. Sk. i. 579. L. monticola, Nutt. Gen. addend. — Mostly on 

 dripping rocks, Western N. Carolina to Florida. 



Var. saxicola. Apparently only a smaller form, barely a span high, with more leafy 

 stems, shorter internodes, and capsule (as far as seen) little surpassing the calyx. — 

 Lindernia monticola, Muhl. Cat. 61 ? L. saxicola, M. A. Curtis in Am. Jour. Sci. xliv. 83. 

 Ilysanthes saxicola, Chapm. Fl. 294. — Mountains of S. W. North Carolina to E. Florida.
