|discussion=<p>Species 3 (2 in the flora).</p><!--
--><p>Five species have been described in the genus; most authors accept <i>Conopholis</i> as including only from one to three species (R. R. Haynes 1971; A. G. Rodrigues et al. 2011, 2013). All taxa in the genus are strikingly similar morphologically. Differences in scale leaves, floral bracts, flowers, vestiture, and plant size have been used to separate species and varieties; the variability of these characters within taxa occasionally exceeds between-taxon differences. There is considerable overlap in any character set used to separate taxa. J. W. Thieret (1971) suggested that all taxa could be considered conspecific. Molecular and morphological studies by Rodrigues et al. (2011, 2013) provided strong evidence that three species should be recognized. The third taxon, C. panamensis Woodson, is known only from Central America. Hosts are all members of <i>Quercus</i> (Fagaceae).</p><!--
--><p><i>Conopholis</i> fruits develop a woody texture at maturity. Although members of the family are generally stated to produce capsular fruits, those of <i>Conopholis</i> generally remain indehiscent until degraded by either physical abrasion or invasion by predatory insects, such as ants. Seed dispersal tends to be of two types: short-range dispersal by the action of gravity, wind, and/or water following the breach of the wall; and longer-range dispersal following ingestion of the plants by various mammals.</p>
