Small tree 1.5-6m tall with somewhat tetragonal and ridged stems in newer branches that are moderately to densely brown scurfy with dendritic or pinoid hairs; the nodal line present. Leaves at a node equal to unequal in length. Petiole 0.3-2 cm long. Leaf blade 4.2-28.4 × 1.4-9.2 cm, 5-plinerved, with the innermost pair of veins usually diverging from the midvein upt to 5 cm cm above the base in opposite to alternate fashion, elliptic, the base gradually tapering to decurrent on the petiole, the apex acuminate to long acuminate, margin entire to undulate, adaxial surface sparsely pulverulent to glabrous, the abaxial surface moderately and deciduously scurfy-pulverulent with short dendritic hairs evident mostly on the veins. Inflorescence a terminal panicle 4.4-11.2 cm long, branching above the base, accessory branches absent, brown scurfy on the branches; bracteoles 0.3-0.75 × 0.2-0.5 mm, subulate, persistent, fused and forming a nodal collar or ridge. Pedicel 0.5-2 mm. Flowers 5 merous, not calyptrate. Flower buds 3-3.75 × 1.3-1.6 mm; hypanthium 1.25-1.75 × 1.25-1.75 mm, campanulate, deciduously scurfy-pulverulent, calyx tube 0.2-0.3 mm long, calyx lobes depressed-triangular to undulate, 0.5 mm long but concealed and barely exceeded by the exterior subulate teeth, androecial fringe present and beset with glandular hairs. Petals 2.75-3.25 × 0.75-1 mm, translucent white to white with or usually without pinkish tinges towards the base, linear-oblong, spreading to reflexed at anthesis, glabrous the apex narrowly rounded to acute. Stamens 10, 2.25-2.75 mm, radially arranged around the style, the filaments 1.25-1.5 mm long, with a geniculation near the apex, white, anthers 1-1.25 0.25-0.4 mm, oblong, yellow, laterally compressed, the pore ca. 0.1 mm wide, somewhat dorsally inclined. Ovary 5 locular, 3/4 to 4/5 inferior, glabrous apically. Style 3.5-4.25 mm long, curving towards the apex, vertical distance from the anther pore to the stigma 1.5-2 mm, horizontal distance absent or up to 1 mm, stigma truncate, ca. 0.35 mm wide. Berry 3-4 × 3-4 mm, purple-black. Seeds 0.35-0.5 mm, pyramidate, smooth with verruculose angles.

Conostegia consimilis is a common species especially in lowlands and middle elevation in Costa Rica and Panama. It can be recognized by its large leaves with decurrent bases and strongly plinerved venation. Its flowers are quite small and its petals are quite narrow and somewhat acute at the apex which prompted in its original description in the genus Leandra . Other useful characters are its yellow anthers, exserted styles, and angulate seeds with verruculose angles. In general, Conostegia consimilis shares its rusty indument and petal shape with its close relatives which include Conostegia iteophylla , Conostegia jefensis , Conostegia peltata , and Conostegia trichosantha . Of the latter taxa, it is most similar to Conostegia iteophylla and the common morphotype of Conostegia jefensis . From Conostegia iteophylla it can be distinguished by its much larger leaves, and from Conostegia jefensis by its white petals (vs. magenta). The drawing in the protologue ( Almeda 2000) evidences the exserted style which is common in section Geniculatae .
