vulgaris, Linn. Hardy native aquatic plant, with 

 crowded, 2-3-pinnately divided floating lvs. % in. long, 

 provided with numerous bladders aud yellow fls. K in. 

 long or more, borne in 3-20-fld. racemes. June-Aug. 

 Brooks and ponds, Eu., Asia, N. Amer. B.B. 3:191. 

 Gn. 28, p. 403.— Advertised by American aquatic spe- 

 cialists and collectors of native plants. 



montana, Poir. Tropical American epiphyte, with 

 clusters of tubers %-% in. long, minute, deformed, 

 useless bladders and large white fls. with a yellow 

 palate, the fls. 1-4 on a scape, each IK in. across. Lvs. 

 4-6 in. long, elliptic-lanceolate. Trunks of trees, West 

 Indies and S. Amer. B.M. 5923. F.S. 19:1942. I.H. 

 18:64.— A lovely species. 



bifida, Linn. Terrestrial species from tropical Asia, 

 with minute bladders and small yellow fls. resembling 

 a diminutive Linaria or Butter and Eggs. Lvs. densely 

 matted, erect, thread-like, 1-2 in. long: fls. yellow, with 

 an orange pale, 3 A in. long, 5-8 in a raceme: pedicels 

 drooping in fruit. India, Malaya, China, Japan, Phil- 

 ippines. B.M. 6689. — Once cultivated at Kew. 



janthina, Hook. Epiphytic Brazilian species growing 

 in the leaf -axils of a bromeliad (Vriesia), with kidney- 

 shaped lvs, and beautiful pale blue or lilac fls. 1^ in. 

 across, ornamented by 2 vertical yellow lines on the 

 palate edged with dark violet. Lvs. with stalks 4-6 in. 

 long and blades 2-4 in. across : scape about 6-fld. : up- 

 per lip hemispheric, arching: lower lip transversely 

 oblong, entire. B.M. 7466. -Int. by Sander, 1892. 

 "Janthina" is the same as "ianthina," meaning violet- 

 colored. 



reuifnrmis, A. St. Hil. Brazilian species found in 

 sphagnum bogs, having kidney-shaped lvs. and rose- 

 colored fls. with 2 darker lines on the palate: upper lip 

 truncate, emarginate; lower lip 3-lobed, the lateral 

 lobes broad, the midlobe much 'shorter and scarcely 

 produced. Brazil. — Once advertised by John Saul, but 

 probably lost to cultivation. Very large for the genus, 

 the lvs. %-l ft. long and scapes 1K-2 ft. high. 



Humboldtii, Schomb. Guiana species, with long- 

 stalked, cordate or obcordate, mostly solitary lvs. and 

 dark purple-blue fls. 2K in. across, with a triangular 

 lower lip. Scapes about 5-fld. F.S. 13: 1390. -One of 

 the showiest species. Commonly cult, in Eng., appar- 

 ently not in America. 



Endresii, Reichb. Epiphytic Costa Rican species, 

 with tubers about % in. long, solitary lvs. and pale lilac 

 fls. l%-2 in. across, with a yellow palate: lvs. 1-3 in. 

 long, narrowly elliptic-lanceolate: scape about 5-fld. 

 B.M. 6656. Var. majus, Hort., was offered by Pitcher 

 & Manda, 1895.— A deciduous species found at altitude 

 of 2,000 feet. 



longiiolia, Gardn. Fig. 2624. A Brazilian species, the 

 typical form of which is perhaps not iu cultivation. U. 

 Forgetiihia, Hort., introduced by Sander, is said by the 

 Kew authorities to be a form of this species and the same 

 as the plant figured in Gn. 52:1132 (adapted in Fig. 2624) 

 under the erroneous title of U. latifolia. It has beauti- 

 ful violet-purple fls. nearly 2 in. across, with a yellow 



palate. ^'Lvs. lanceolate, erect: scapes 12-20-fld. and fls. 

 last well. G.C. III. 13:713. W. M. 



UVULARIA (Latin, uvule, palate, referring to the 

 hanging flowers). Liliaceo?. Bellwort. "Wild Oats' 

 in some parts. A genus of two species of very grace 

 ful woodland, perennial herbs native to North America 

 The plants grow about 15 in. high, with a number ol 

 clustered slender stems which are forked and leaf 

 bearing mainly above. The foliage is of a delicate green 

 which with the terminal, narrow, bell-shaped, drooping 

 flowers make the plants elegant though not showy. 

 The species are perfectly hardy and easy of cultivation 

 in any light, rich soil and a shady situation. They do 

 well north of a wall in a well-prepared border and in 

 such a position they far exceed the plants of the woods 

 in luxuriance. Strong roots may be slowly forced for 

 spring flowering. For distinction from Oakesia, see 

 that genus, to which some of the plants commonly 

 known as Uvularias are referred. 



2625. Bellwort — Uvularia perforata (X %) 



a. it's, pubescent beneath. 

 grandiflora, Sm. Stems 1-1K ft. high, with 1 or 2 

 lvs. below the fork: lvs. oblong, oval or ovate, some- 

 what acuminate: fls. pale yellow, 1-1J£ in. long; seg- 

 ments tisually smooth on both sides: stamens exceeding 

 the styles: capsule obtusely 3-angled, truncate. May, 

 June. Rich woods, Quebec to Minn, south to Ga., 

 Tenn. and la. B.B. 1:409. 



aa. Lvs. not pubescent beneath. 

 perfoliata, Linn. Fig. 2625. Stems more slender than 

 in U. grandiflora, with 1-3 lvs. below the fork: lvs. 

 oval, oblong or ovate: fls. pale yellow, about 1 in. long; 

 segments glandular papillose within; stamens shorter 

 than the styles: capsule obtusely 3-angled, truncate. 

 May, June. Rich woods, U. S.
