Type
Type: Brazil, Rio de Janeiro, Pohl [9] (W, holo.; PR, iso., fide Plowman in Fieldiana, Bot., n.s. No. 39: 113 (1998))
Morphology General Habit
Shrubs 0.5–3 m tall, deciduous, often branched from base.
Morphology Branches
Branches many, slender, glabrescent; hairs on all parts short, eglandular
Morphology Leaves
Leaves often glossy, elliptic, obovate or lanceolate, 2.5–8 × 1–4 cm, bases cuneate, often decurrent, margins entire, apices acute to obtuse, membranaceous to coriaceous, both surfaces glabrous to sparsely pilose; petioles 1–5 mm
Morphology Reproductive morphology Inflorescences
Inflorescences 1-flowered, terminal, sessile, occasionally with peduncles 1–5 mm long, slender, glabrous to glandular-pubescent, subtended by 1–3 broadly ovate or linear-lanceolate bracts 1–5 mm long; pedicels erect, 1–6 mm
Morphology Reproductive morphology Flowers Calyx
Calyx tubular or tubular-campanulate narrowing towards base, 10–22 × 1.2–2.2 mm basally widening to 5–10 mm above, with five acute and often unequal broadly triangular or obovate lobes 2.5–5.8 × 1.6–4.2 mm, glabrous
Morphology Reproductive morphology Flowers Corolla
Corolla white or purple with a white eye at the throat, usually fading to white or yellow, hypocrateriform, tube cylindrical 1.3–2.5 cm long and 1–2 mm wide, widening around anthers and stigma, terminating in five broadly ovate spreading rounded lobes 1.2–2(–3) cm long and wide; apical flower diameter 1.8–4.8 cm; glabrous or sparsely pubescent externally
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens usually included; filaments unequal, lower posterior pair free for 1–3 mm, upper lateral pair free for 1.5–3 mm; anthers orbicular-reniform, medifixed, 0.7–1 mm diameter, lateral pair often visible in corolla throat
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary conical to ovoid, 1.8–3 × 1–1.5 mm, glabrous; disc smooth; style 15–23 mm long, usually included; stigma 0.6–0.8 × 0.7–1.5 mm
Morphology Reproductive morphology Fruits
Fruit a glossy dark green, coriacous, globose or ovoid capsule 7–8 × 8–18 mm, smooth, thin-walled, partially enclosed by accrescent coriaceous persistent calyx, occasionally dehiscent
Morphology Reproductive morphology Seeds
Seeds numerous, reddish-brown to black, cuboidal to obovoid, 3–5 × 2–3 mm, angulate
Figures
Fig 2/1–6, p 19
Ecology
Cultivated and sometimes an escape in gardens and on roadsides; 1050–1200 m
Conservation
Widespread; least concern (LC)
Note
This species is particularly variable in leaf size and shape, calyx length, and pubescence degree and location. It is often known as ‘Yesterday, today, tomorrow’ because of the changes in flower colour that occur with age. These names were used for plants identified as B. latifolia [no authority given] in U.O.P.Z. (1949). However, although the inflorescences were described “with flowers borne several together”, all other features and floral dimensions suggest that the plants belong to B. uniflora. It is possible that they were mis-identified. The flowers are said to be pollinated by day-flying butterflies from several different families.
