Septal spines are absent and tabulae are infundibuliform as in Syringopora.

Corolla salveriform to infundibuliform or rarely tubular campanulate; aestivation sinistrorse in Wrightia, Pleioceras, and Stephanostemma; often with conspicuous corona of flat, petaloid segments in mouth.
Calycine colleters mostly in alternisepalous groups or in continuous ring, more rarely solitary and episepalous; corolla usually divided into narrow lower tube and expanded upper throat, mostly infundibuliform or tubular campanulate, more rarely tubular or salveriform; corolla-lobe aestivation dextrorse; distinct corona usually absent; stamens mostly inserted at base of throat; lignified guide rails long, well developed; style head with neither basal collar nor upper wreath, with 5 arms, which usually project from lower part (arms forming long ridges for most of length of style head in Mandevilla and Macrosiphonia) to which anthers are attached; stigmatic zone confined to re gion on underside or lower region of style head.
Calycine colleters often one, episepalous, or several and spread across base of sepal, rarely absent; corolla salveriform, infundibuliform, tubular campanulate, campanulate (rotate in Parsonsia, Artia, Ecua, and Thernardia); corolla-lobe aestivation dextrorse, rarely valvate; stamens mostly inserted in upper part of corolla tube (near base in Parsonsia, Artia, Ecua, Pottsia, and Thernardia); anthers often partially to almost completely exserted, with large, lignified guide rails, attached near base of style head; style head cylindrical to narrowly fusiform, broadest and with (usually well developed, often membranous) collar at base and sometimes upper wreath as well; stigmatic zone located on underside of style head beneath collar.
In the latter species, there was a change in shape of most coenanthia at early male phase, from infundibuliform (Fig.
However, the coenanthia that remained infundibuliform got filled with water during heavy rains.
bonijesu, the coenanthia that retain an infundibuliform shape formed a "water reservoir" where fruits were released, thus preventing the usual dispersal process reported to Dorstenia species.
