A Systematic Investigation of Begonia section Sphenanthera (Hassk.) Benth. & Hook.f
No full textBegonia contains between 900 and 1400 species and is found in most tropical and subtropical regions of the world. The genus is currently divided into c. 80 sections. Several of these are poorly defined and appear not to reflect underlying phylogenetic relationships. This study deals with the systematics of one such taxonomically problematic section from Asia

Stem: stout, ca 10 mm wide, glabrous, internodes 3–8 cm long. Stipules: lanceolate to linear, 7–15 × 2–5 mm, glabrous, deciduous. Leaves: petiole 2–7(–14) cm long, glabrous or very sparsely puberulous; lamina lanceolate-oblong, basifixed, base shallowly cordate to subcordate, 4.5–22 × 1.5–10 cm, strongly asymmetric, upper surface dark green, glabrous, underside pale green, glabrous or sparsely puberulous on veins mostly, venation palmatepinnate, midrib 4.5–15 cm long; margin broadly dentate to denticulate; margin with sparse hairs to glabrous; apex acuminate. Inflorescence: cymose, axillary, numerous; peduncle glabrous, branching 1–2 times, primary and secondary 2–10 mm long, with 1– 2 female and 1– 3 male flowers; bracts lanceolate, 2–12 × 1–5 mm, entire, caduceus. Male flower: pedicel 5–13 mm long, glabrous; tepals 4; outer tepals orbicular to obovate, ca 10 × 9 mm, white to pink, glabrous; inner tepals spathulate, 4–8 × 2–7 mm, white to pink, glabrous; androecium with 30–60 stamens, symmetric; filaments 1–1.5 mm long, free; anthers oblong elliptic, 1–3 mm long, dehiscing through slits about half the length of the anther, not hooded, connective extended. Female flower: pedicel ca 14 mm long, glabrous; bracteoles absent; tepals 4–6, equal, elliptic, 5–16 × 2–6 mm, white to pale pink, glabrous, inner tepals similar yet smaller; ovary 3-locular, placentae bifid; capsule globose, 3–10 × 3–7 mm, glabrous, without wings; styles 3, deeply forked once and twisted twice, deciduous. Fruit: on stout pedicel, globose; capsule spherical, fleshy, glabrous, 6–12 × 8–15 mm. Distribution and phenology Arunachal-Pradesh and Meghalaya; also in China, Myanmar, Thailand, Malaysia Peninsular, Vietnam, Sumatra, Java, Lesser Sunda Islands, Sulawesi and the Moluccas; 200–1550 m. Flowering: May to November; fruiting: June to December. Conservation status Least Concern (Hughes 2008). Begonia longifolia is a very widespread and ecologically tolerant species found throughout Southeast Asia, with no significant change in recent years to warrant a change in its status. Remarks Begonia longifolia is most similar to B. acetosella in vegetative appearance; when fertile it can be easily distinguished as it is monoecious and has 3- (not 4-)locular fruit. The leaves of B. longifolia can approach those of B. sect. Monopteron (B. griffithiana and B. nepalensis), but B. longifolia has an upright habit rather than the pendulous habit of those species. Begonia longifolia forms a natural hybrid with B. palmata where the two are growing together, Begonia × chungii C.I Peng & S.-M.Ku (Peng & Ku 2009) which has been reported from the study area (Morris 2011a). This hybrid has baccate fruit with wings, intermediate in form between the parents. Begonia longifolia is lectotypified here as others (Tebbitt 2003a; Kiew 2005; Gu et al. 2007; Hughes & Girmansyah 2011) have listed a holotype in error as there is no herbarium mentioned in the protologue (McNeill 2014). This is also true of Casparaya trisulcata, B. sarcocarpa and B. tricornis.Published as part of Camfield, Rebecca & Hughes, Mark, 2018, A revision and one new species of Begonia L.
