into many forms, some of which may be specifically 

 distinct. Var. splendidum, Hort., is an improved 

 form, crimson with a yellow circle. Var. giganteum, 

 Hort., is larger in all its parts: Ivs. paler: fls. somewhat 

 earlier, in some forms white. Var. elegans, Hort. Lvs. 

 wider and shorter than the type: scape shorter; fls. 

 more numerous, dark-colored. (The old generic name 

 Meadia commemorates Dr. Richard Mead, 1673- 

 1754.) 



Jeffreyi, Van Houtte (Meadia Jeffreyi, Kuntze). 

 Plant somewhat glandular- viscid : rhizome vertical 

 and short, strong: Ivs. oblanceolate, erect, entire, some- 

 what acute, mucronulate: scape 12-24 in. or more, 

 bearing a many-fld. umbel; calyx-lobes lanceolate; 

 corolla deep red-purple; connective-body of anthers 

 very narrow or subulate at apex, colored same as sta- 

 mens. Mts., Calif, and Ore. F.S. 16:1662. 



tetriindrum, Suksdorf, has the general aspect of D, 

 Jeffreyi, but the Ivs. are ampler and relatively broader: 

 roots, as in D. Jeffreyi, are abundant, fleshy, fibrous, 

 persistent: roots, Ivs. and scapes form a short, vertical 

 crown: whole plant glabrous: corolla purplish, with a 

 yellow ring near the base; segms. and stamens usually 

 only 4: caps, circumscissile very near the apex. Mts., 

 Wash, and Ore. 



frigidum, Cham. & Schlecht. Plant 1 ft. or less: Ivs. 

 obovate to ovate or oblong, acutish, entire or somewhat 

 dentate: scape much exceeding the Ivs., 2-3-fld.; 

 calyx-lobes longer than the tube; corolla-lobes oblong- 

 linear, violet: caps, oblong, twice longer than calyx. 

 Bering Strait to Rockies and Sierras. B.M. 5871. 



latflobum, Elmer (D. dentatum, Hook. D. Meadia 

 var. latilobum, Gray). Larger than the last: Ivs. with 

 blade 1-4 in. long, oval or ovate to oblong, repand or 

 sparingly dentate, abruptly contracted into long- 

 winged petioles, obtuse: fls. 2-4; calyx-lobes deltoid; 

 corolla-lobes oblong, yellowish white: caps, but little 

 longer than calyx, opening from the apex by valves. 

 Wash., Ore., Idaho. 



Hendersonii, Gray. About a foot high, glabrous, 

 deep green: Ivs. small, obovate or elliptic, 1 in. or more 

 long, narrowed to a short petiole : fls. rather few ; calyx- 

 lobes triangular, acuminate, twice exceeding the tube; 

 corolla-lobes dark purple with a yellow base, the stami- 

 na! tube dark purple; anthers oblong, obtuse, short- 

 apiculate; connective-body deep purple: caps, ovoid, 

 much exceeding the calyx, dehiscent by a circumscissile 

 apex and splitting into 10 valves. Calif, to Wash. 

 G. 33:391. 



Cleveland!!, Greene. One to 1^ ft. tall, glabrous: 

 Ivs. pale green, thickish, spatulate-ovate, petioled: 

 fls. 2-10; calyx-lobes ovate-lanceolate, acute, glandular; 

 corolla-lobes purple with yellow base and a few purple 

 spots in throat; anthers purple, the connective -body 

 yellow: caps, oblong, circumscissile at apex. Feb.- 

 May. S. Calif. Fls. said to vary to pure white. 

 Fragrant. 



radicatum, Greene. Glabrous: -root short and corm- 

 like with fibrous rootlets: Ivs. 3-5, thin, light green, 

 oblong-spatulate, crenate or nearly entire, blade 

 attenuate into petiole of about equal length: fls. 3-5 

 or more on a stout scape 8-16 in. tall; calyx-lobes 

 lanceolate, about as long as the tube; corolla pinkish 

 or bluish violet, the lobes oblong-linear and erect- 

 spreading; staminal tube short; anthers purple, acute: 

 caps, narrow-ovate, only slightly surpassing calyx- 

 lobes. April. Wyo. to New Mex. Recommended for 

 alpine and rock-gardens. L H B t 



DODONJEA (Rembert Dodoens, or Dodonseus, 

 about 1518-1585, royal physician and author). Sapin- 

 dacese. Trees and shrubs, somewhat planted in S. Fla. 

 and S. Calif, for ornament. 



Leaves alternate, without stipules, simple or pin- 

 nate: fls. small, polygamous, unisexual, often dioecious, 



terminal or axillary, solitary or in racemes or panicles; 

 sepals 5 or fewer; petals wanting; stamens mostly 8 

 (5-10) with very short filaments; ovary 3-6-celled, 

 each cell 2-ovuled: caps, winged on the back of each 

 valve. About 50 species, mostly in Austral., a few 

 in Afr. and in Hawaii and N. Amer. Lvs. sometimes 

 glandular and exuding resin-like or varnish-like sub- 

 stance. 



viscdsa, Linn. Shrub, to 15 ft., viscid: Ivs. mostly 

 oblong, cuneate at base, entire, with resinous dots on 

 both surfaces: fls. greenish, in short terminal or axillary 

 racemes; sepals ovate: caps about Min- long and some- 

 what broader, broadly 3- winged, notched at apex, 

 more or less cordate at base. B.R. 13:1051 (as D. 

 oblongifolia) . A poorly defined plant, widely distributed 

 in warm countries, occurring in Austral., S. Afr., in 

 Mex., and forms of it in Fla. and Ariz. Lvs. varying 

 from broadly spatulate to oblong to nearly or quite linear. 



Thunbergiana, Eckl. & Zeyh. Shrubs, 6-10 ft., 

 glabrous, much branched: Ivs. lanceolate or linear- 

 lanceolate, narrowed at base, somewhat denticulate 



1339. Leaves of Dolichos. A, D. Lablab; B, D. lignosus. 



and somewhat viscid : fls. green, polygamous, racemose : 

 caps. Hin. long, resinous and shining, 2-3-winged, as 

 long as the stalk or longer. S. Afr. 



triquetra, Andr. Erect shrub, the young branches 

 flattened or very angular: Ivs. oval-elliptic to oblong- 

 lanceolate, acuminate, to 4 in. long, entire or very 

 nearly so: fls. in short oblong compact panicles or 

 racemes; sepals minute: caps, of D. viscosa, middle- 

 sized. Austral. 



cuneata, Rudge. Much-branched bush, usually 

 viscid: Ivs. small (usually under 1 in. long) obovate or 

 cuneate, at the end rounded or truncate or toothed, 

 on the sides entire or rarely obscurely toothed, short- 

 petioled : fls . in short terminal scarcely branched 

 racemes, or sometimes few in axillary clusters; sepals
