Form (botany) group with a noticeable morphological deviation. The usual taxonomic practice is that the individuals classified within the form are not necessarily known to be closely related (they may not form a clade). For instance, white-flowered plants of species that usually have coloured flowers can be grouped and named (e.g., as "f. "alba""). Formae apomicticae are sometimes named among plants that reproduce asexually, by apomixis. There are theoretically countless numbers of forms based on minor genetic differences, and only a few that have particular significance are likely to be named.

Calyx podatypa Calyx podatypa Calyx podatypa is a species of demosponge belonging to the Phloeodictyidae family. It is native to the Caribbean. The species was first described in 1934 by American spongiologist Max Walker de Laubenfels. It is commonly found in shallow reefs, among seagrass and on mangrove roots. It is described as being mostly hollow with growths that range from branched to lobate in shape and tubular projections. It has round openings between 1-5mm in size. The colour is "Brown-yellowish to greenish" on the outside and tan on the inside. A number of biologically active compounds have been isolated from "Calyx
