Description.

Shrubs to trees 1.5-8(-14) m tall with flattened stems in newer branches that are densely covered with ferrugineous stellate hairs often intermixed with plumose hairs; the nodal line inconspicuous. Leaves of a pair equal to unequal in length. Petiole 1-4.8 cm. Leaf blades 5-25.8 × 2-10.1 cm, 3-5(-7)-plinerved, with the innermost pair of primary veins diverging from the midvein 0.8-4.5 cm above the base in opposite or commonly alternate fashion, narrowly elliptic-lanceolate to elliptic-ovate, the base acute to obtuse but sometimes varying to asymmetrical, the apex acuminate, the margin obscurely to conspicuously undulate-denticulate, the adaxial surface glabrous or with few trichomes on the main veins, the abaxial surface covered with ferrugineous stellate hairs often intermixed with plumose hairs on the primary veins. Inflorescence a terminal few flowered panicle 2-5.2 cm long branching at or above the base, accessory branches absent, the rachis with a ferrugineus indument like the young stems, bracteoles 1-3 mm, linear, deciduous. Pedicel 0.5-2 mm. Floral buds 6.5-7.5 × 4-5 mm. Flowers 5-merous, calyx not calyptrate or fused in bud, stellulate within, the hypanthium 3.75-4.25 × 5.25-5.5 mm, slightly constricted at the torus especially when going into fruit, ferrugineus, calyx lobes flange-like, 1-1.5 mm long, calyx teeth small and tuberculate, barely exceeding the calyx lobes. Petals 9-14 × 8-10 mm, white, obovate, spreading at anthesis, rounded-emarginate at the apex, glabrous on both surfaces. Stamens 10, 9.5-10.5 mm, radially arranged in the middle of the flower, the filaments 4.75-5.25 mm, white, anthers 4.5-5 × 1.25-1.75 mm, oblong, yellow, the pore 0.15-0.2 mm, ventrally inclined. Ovary 5-locular, inferior, the apex shallowly fluted and glabrous. Style 12-14.5 mm, straight or strongly bent, vertical distance between the anthers and stigma ca. 1.5-3 mm, horizontal distance 0-3 mm, stigma capitate, ca. 1 mm wide. Berry 8-10 × 8-10 mm, purple. Seeds 0.45-0.7 mm long, deltoid, smooth and angulate.

Conostegia schlimii  is one of the most common species of Conostegia  and an easy one to recognize. It has a conspicuous rusty indument on branch apices, the leaves are evidently plinerved and frequently with asymmetrically arising primary veins, as well as an undulate-denticulate margin. The flowers are quite large and have distinctive basally clawed petals, large bright yellow anthers and a capitate stigma. It is one of the largest flowered species in the genus and one of the few large flowered species not to be pleiostemonous. Its berries are also quite large. Flowers of this species have been observed being buzzed by Melipona costaricensis  in the Osa Peninsula of Costa Rica. For such a common species in the Pacific slope of Costa Rica as well as being present towards the Caribbean slope in Nicaragua, Honduras, Guatemala and Belize, it is suprising it is absent in the Caribbean slope of Costa Rica. Based on morphology, Conostegia schlimii  is hard to confuse with any other taxon. Perhaps the one that most closely resembles Conostegia schlimii  , based on floral size and general morphology is Conostegia incurva  . The latter differs in its leaf abaxial surface being covered with indument and most noticeably in its claw like, conspicuous, calyx teeth.
