Description

Genus Uvularia

Herbs, caulescent , glabrous or pubescent , from short or elongate rhizomes bearing several fibrous or thickened roots . Stems simple or 1-branched, excluding flower-bearing branches, strongly angled or rounded , with sheathing , papery bracts proximally. Leaves alternate, sessile or perfoliate; blade oblong-linear to oblong-ovate, membranaceous to leathery. Inflorescences 1 per branch , terminal but appearing axillary ; peduncles pendent. Flowers: perianth narrowly campanulate ; tepals promptly deciduous, imbricate, distinct , linear to narrowly oblong , apex obtuse or acute, nectariferous ; stamens distinct to weakly connate at perianth base; filaments dimorphic , glabrous; anthers linear-oblong, extrorse ; connectives present; ovary superior, 3-locular, sessile or stipitate , rounded to sharply triangular; style 1, 3-lobed; stigmas 3, lobed , outwardly arching at maturity. Fruits capsular , greenish to yellowish brown, sessile or stipitate, leathery or submembranaceous, tardily dehiscent , dehiscence loculicidal. Seeds 1-3 per locule, brownish red, globose to ovoid ; arils various. x = 6, 7.

Species 5: e North America.

Uvularia, a genus of attractive, spring-blooming plants , has been divided into sect. Oakesiella (Small) Wilbur with sessile leaves and sect. Uvularia with perfoliate leaves. Differences in other morphological (R. L. Wilbur 1963) and cytological (F. H. Utech 1978d) characters support recognition of these infrageneric groups.

D. K . Wijesinghe and D. F. Whigham (1997, 2001) compared the different, below-ground, vegetative morphologies of three Uvularia species and their relationship to their differing clonal populations and dynamics.[1]

Physical Description

Species Uvularia puberula

Rhizomes short, 0.5-1 cm, bearing numerous , clustered, fleshy roots ; stolons absent. Stems 1-several, 1-branched, angled and puberulent distally, especially at nodes, 1-4.5 dm, bearing 1 leaf below lowest branch . Leaf blades sessile, broadly oblong-elliptic, 4-8(-8.5) × 1.5-3.5(-4) cm, puberulent on abaxial veins, margins minutely papillose , apex acute to acuminate. Flowers 1-3 per stem; peduncles 0.5-2 cm, ebracteate ; tepals greenish to pale yellow, 10-25 × 2-4 mm, smooth adaxially, apex rounded ; stamens 6.5-17 mm; anthers 5-12 mm; connectives 0.6-0.8 mm; ovary sessile or subsessile , sharply triangular; style 8-14 mm; stigma lobes 4-6 mm. Capsules sharply 3-winged, broadly ellipsoid , 1.5-3.7 × 1-2 cm, not beaked . Seeds 3-3.5 mm; arils crested . 2n = 14. [source]
