Nymphoides beaglensis Aston
- Aston, H.I. 1987. Nymphoides beaglensis (Menyanthaceae): a new Australian species. Muelleria 6(5):359-362.
|
Laminae foliorum integrae, latissime ovatae ad ± rotundatae, profunde cordatae sino angusto, c. (20-)25-50 mm longae x c. 22 mm latae. Petiolus folii, quod inflorescentiam sustinet, conspicuus c. 1.5-7.5 mm longus, quam lamina paulo brevior ad fere duplo longior. Inflorescentia c. 7-17 pedicellorum vel dense aggregatorum vel per rhachim ad 18 mm longam approximatorum formata; nonnumquam 2-4 inflorescentiae contiguae una ut videtur. Flores heterostylosi, 5-partiti. Corolla c. 18-22 mm lata, alba vel alba subroseo-malvacea suffusa, atromarronino-malvacea in fauce; lobi corollae alis lateralibus latis, haud profunde laciniatis, praediti; glabri praeter duos conspicuos fasciculos caespitosos pedicellatos capillorum papillosorum, singulos in lateribus basi loborum; papillae tubi corollae simplices, breves, c. 0.3-0.8 mm longae, c. 50-70 aggregatae in fasciculo denso sessile vel subsessile. Capsula ellipsoidea ad late ellipsoidea, 3.5-6.0 mm longa. Semina c. 33-64 in capsula, paene globosa, minime ad modice utrinque compressa, 0.75-0.95 mm longa x 0.70-0.85 mm lata x 0.55-0.70 mm crassa, maturitate atrofumosa; pagina caespitibus tuberculorum 1-8 erectorum obtusorum, ad 0.5 mm longitudine vel dispersis vel solis, apud iuxtaque marginem; caruncula basalis circularis, pallida, crassa, conspicua.

Laminae of leaves entire, broadly ovate to ± rounded, deeply cordate with a narrow sinus, c. (20-)25-50 mm long x c. 22 mm broad. Petiole of leaf conspicuous, because it supports the inflorescence, 1.5-7.5 mm long, a little shorter than the lamina, up to about twice as long. Inflorescence formed from c. 7-17 pedicels, either densely aggregated or associated on a rachis up to 18 mm long; never are 2-4 inflorescences contiguous as one, as has been seen. Flowers heterostylous, five-parted. Corolla c. 18-22 mm broad, white or white suffused with subrosaceous-malvaceous, dark purple-malvaceous in throat; lobes of corolla with broad lateral wings, scarcely deeply fringed, [praediti]; glabrous apart from two conspicuous, cespitose, pedicellate
fascicles of papillose hairs, single at the base on the sides of the lobes; papillae of corolla tube simple, short, c. 0.3-0.8 mm long, c. 50-70 aggregated in a dense, sessile or subsessile fascicle. Capsule ellipsoid to broadly ellipsoid, 3.5-6.0 mm long. Seeds c. 33-64 in capsule, almost globose, each minimally to moderately compressed, 0.75-0.95 mm long x 0.70-0.85 mm broad x 0.55-0.70 mm thick, dark [fumosa] at maturity; leaf with 1-8 hairs of erect, obtuse tubercles, to 0.5 mm in length, or dispersed, or solitary, on and about the margin; basal caruncle circular, pale, thick, conspicuous.

N. triangulari Aston atque N. elliptica Aston et corollae colore et petiolo longo folii quod inflorescentiam sustinet similis; differt, tamen, praecipue in magnitudine sculpturaque seminis, in dispositione capillorum in lobis corollae, et in papillorum tubi corollae.
|
Similar to N. triangularis Aston and N. elliptica Aston in color of the corolla and long petiole of the leaf that supports the inflorescence. Differs, however, principally in the size and sculpture of the seed, in the disposition of hairs in the lobes of the corolla, and in the disposition of hairs on the corolla tube.
