Description:
Author: Ghillean T. Prance & Scott A. Mori
Type: Guyana. Bartica-Potaro Road, mile 84, 20 Jun 1933 (fl), Tutin 200 (holotype, BM; isotypes, K, US).
Description: Trees, to 30 m tall, the young branches minutely puberulous, soon becoming glabrous. Leaves not documented to flush just before anthesis (see Prévost & Sabatier 2961 but this needs to be confirmed; petioles 13-18 mm long, minutely puberulous, canaliculate, not winged; blades obovate-oblong, 10.5-16.5 x 4.8-8.5 cm, coriaceous, glabrous on both surfaces except midrib sparsely puberulous abaxially, the base rounded to subcuneate, often unequal, the margins entire, revolute, the apex acute to bluntly cuspidate; venation with midrib prominulous adaxially and prominent abaxially, the secondary veins in 11-14 pairs, prominulous adaxially, prominent abaxially, the tertiary venation prominulous on both surfaces. Inflorescences terminal or axillary, paniculate arrangements of racemes, the rachises sparsely brown-tomentellous; pedicels 3.5-4 cm long, brown-tomentellous. Flowers with hypanthium campanulate-turbinate, ca. 8 mm long; calyx lobes 5-7.5 x 6-8 mm, ovate, puberulous on both surfaces, the margins ciliate; petals oblong, 2.7-3 cm long, stellate pubescent abaxially, slightly ciliate at margins, red abaxially, pink and white adaxially (fide protologue) or various shades of violet (fide Prévost & Sabatier 2961); androecium ca. 3 cm long, glabrous, the staminal ring ca. 10 mm in diam., the exterior of hood rugulose but not echinate, the stamens ca. 65, grouped in several rows around staminal ring; ovary 3-locular. Fruits not known at maturity, the immature ones of Prévost & Sabatier 2961 with inconspicuous lenticels, the pedicel twice as long as fruit.
Common names: French Guiana: mahot cigare. Guyana: wadara. Both names are widely applied to various species of Couratari.
Distribution: Known only from the type gathering and several collections from French Guiana.
Ecology: Couratari calycina is a canopy tree reported from primary forest (Prévost & Sabatier 2961), riparian forest (Prévost & Sabatier 4042), and forest on white sand (Loubry 2401) in French Guiana. The type was collected in "clump wallaba bush." (Sandwith, 1955).
Phenology: Flowers in Jun in Guyana based on the type and in Jan in French Guiana (Prévost & Sabatier 2961.
Pollination: No observations recorded but most likely pollinated by bees.
Dispersal: Like all species of Couratari, C. calycina possesses winged seeds which are dispersed by the wind.
Field characters: Couratari calycina is characterized by its relatively large, coriaceous leaves; long pedicels; and violet colored petals. It is not known for sure if this species flowers with the leaves fully lignified but Prévost & Sabatier 2961 indicate that it does. Other species in this section drop their leaves and then flush new leaves just the trees have flowered.
Taxonomic notes: Couratari calycina is placed in Couratari sect. Couratari by Prance in Mori and Prance (1990). Mature the fruits of this species are not known, but the immature ones of Prévost & Sabatier 2961 are subtended by long pedicels and the pericarp is inconspicuously lenticellate.
Uses: None recorded
Etymology: The species epithet refers to the calyx and this is alluded to in the protologue as follows "C. calycina is not the only Couratari with large sepals..."
Source: Based on Prance in Mori & Prance (1990).
Acknowledgements: We are grateful to D. Sabatier for allowing us to use his images to illustrate the characters of this species.
