 be planted in the open border about the end of May, in a warm 

 sheltered situation. 



XXVII. DODA'RTIA (so named by Tournefort after M. 

 Dodart, member of the Academy of Sciences at Paris, and phy- 

 sician to the princess dowager of Conti.) Tourn. inst. 478.

LIN. SYST. Didynamia, Angiospermia. Calyx campanulate, 

 short, angular, 5-toothed. Corolla tubular ; limb bilabiate ; 

 upper lip emarginate : lower lip broader and trifid, twice the 

 length of the upper one. Stamens 4, didynamous, inclosed ? 

 anthers small, roundish, twin. Stigma 2-lobed. Capsule glo- 

 bose, covered by the calyx, 2-celled ; placentas convex, growing 

 to the dissepiment. An herbaceous glabrous plant, with creeping 

 roots ; branched, or simple, solitary stems. Leaves distant : 

 lower ones opposite : upper ones alternate, linear, entire.

1 D. ORIENTA V LIS (Lin. spec. p. 883.) 3 . H. Native of 

 Tartary ; and on Mount Ararat. Mill. fig. 127. Sweet, fl. 

 gard. t. 147. Lower leaves serrated: upper ones entire. 



Eastern Dodartia. Fl. July, Aug. Clt. 1739. PI. 1 to U 

 foot. 



Cult. The plant loves a light dry soil, and a warm sheltered 

 situation. It propagates very fast by its creeping roots ; so 

 that when once established in a garden, it will multiply fast 

 enough. 



XXVIII. MA'SUS (from /uao-oc, warns, a teat ; tubercles 

 closing mouth of corolla.) Lour. coch. p. 385. R. Br. prod. 



. 439. Benth. scroph. ind. p. 26. Hornemannia species, 

 ink. Gratiola species, Horn. 



LIN. SYST. Didynamia, Angiospermia. Calyx campanulate, 

 5-cleft, nearly equal. Corolla bilabiate ; upper lip bidentate or 

 bifid : lower one longer, trifid, furnished with 2 gibbosities at 

 the base ; lobes entire. Stamens 4, didynamous, inclosed ; fila- 

 ments entire ; anthers cohering, or approximating by pairs ; 

 cells diverging or divaricate, but at length confluent. Stigma 

 bilamellate. Capsule 2-valved, with a loculicidal dehiscence ; 

 valves entire, bearing the dissepiment in the middle ; dissepi- 

 ments at length free ; placentas adnate to the dissepiment. 

 Humble herbs, generally creeping or procumbent. Radical 

 leaves numerous, petiolate, coarsely toothed or lobed : those of 

 the sterile branches opposite ; but those of the floral ones are 

 few and alternate. Racemes of the floral branches, or of the 

 scapes, naked, terminal, unilateral. Flowers alternate, pedicel- 

 late. Bracteas none, or 1-2 on a pedicel. 



1 M. SURCULOSUS (D. Don, prod. fl. nep. p. 86.) stolons 

 creeping ; leaves deeply crenated, wrinkled, hispid, and a little 

 curled ; those of the sterile branches roundish ; segments of 

 calyx shorter than its tube, ovate, obtuse ; corolla hardly twice 

 the length of the calyx. If.. F. Native of Nipaul, Kamaon, 

 and Mussooree. Herb hairy. Racemes radical, pilose, or 

 scapes racemose. Corollas size of those of Masus rugcsus, but 

 the plant is more branched. 



Surculose Masus. PI. creeping. 



2 M. RUGOSUS (Lour. coch. 385.) hardly stoloniferous ; leaves 

 all oblong, cuneated, coarsely toothed ; segments of the calyx 

 ovate-lanceolate or lanceolate, acute, equal in length to the 

 tube; corollas hardly twice the length of the calyx. 0. H.

 procumbent. 



3 M. DENTA'TUS (Wall. cat. no. 3914. Benth. scroph. ind. 

 p. 27.) stolons none ; leaves ovate, sinuated ; corolla 3 times 

 the length of the calyx. . ? H. Native of Nipaul. Leaves 

 larger, broader, smoother, and less lobed than the preceding ; 

 and the corolla is double the size. 



Toothed-leaved Masus. PI. J foot. 



4 M. PUMI'LIO (R. Br. prod. p. 439.) superior lip of corolla 

 deeply bifid; scapes 1-4-flowered, and are, as well as the 

 calyxes, glabrous. 0. ? H. Native of Van Diemen's Land. 

 Flowers purple ?

5 M. L^EVIFOLIA (Blum, bijdr. p. 753.) leaves spatulate, 

 repand, smooth on both surfaces ; racemes terminal, loose, 

 glanduliferous. . H. Native of Java, in humid places about 

 Buitenzorg. 



Smooth- leaved Masus. PI. trailing. 



Cult. The seeds of annual species require to be reared on a 

 gentle hot-bed ; and when the plants are of sufficient size, but 

 not before the end of May, they should be planted out in a 

 warm sheltered situation in the open ground. M. surculosus, 

 being perennial, will require to be kept in the greenhouse during 

 winter. 



XXIX. LIMNO'PHILA (from Xipvn, limne, a lake ; and 

 4>(\<o, phileo, to love ; in reference to the plants loving water.) 

 R. Br. prod. 442. Benth. scroph. ind. p. 25. Columnea spe- 

 cies, Roxb Gratiola species, Willd. 



LIN. SYST. Didynamia, Angiospermia. Calyx tubular, 5- 

 cleft, equal. Corolla funnel-shaped ; limb somewhat bilabiate ; 

 upper lip 2-lobed : lower lip trifid ; lobes all flat. Stamens 

 4, didynamous ; filaments entire, usually abruptly incurved at 

 apex, sometimes dilated ; anthers cohering by pairs ; cells 

 parallel, distinct. Stigma oblique, dilated, bilamellate. Capsule 

 bisulcate, 2-valved ; valves with a loculicidal dehiscence, bifid, 

 dehiscing slowly ; dissepiment from the margins of the valves, 

 at length free ; placentas adnate. Erect marsh or aquatic 

 herbs. Leaves opposite : lower ones submersed, deeply many- 

 parted, as in Ranunculus aquatilis, with capillaceously multifid 

 segments ; emersed leaves entire, toothed or cut, often tripartite, 

 and hence they appear as if they were verticillate. Flowers
