Corallum tall caespitose; branches arising from almost horizontal stem. Stem and branches almost of same diameter; slightly sinuous; swollen at level of corallites, constricted at intervals between adjoining corallites; generally cylindrical, no palmation even at level of ramification; surface all over (including that of branchlets) appear smooth (terete) because septocostal ridges of even height. One branch has these dimensions; height 8 cm, diameter at base 10 mm, at tip 7 mm, at level of corallite 13.5 mm.
Terminal branchlets with rounded tips; some only slightly tapering, others definitely so. One cylindrical branchlet has following dimensions; height 5.5 cm, diameter at base 9.5 mm, at tip 6 mm, at level of corallite 9 mm. One tapering branchlet: 5 cm high, 7 mm across at base, 2.5 mm at tip, 9.5 mm at level of corallite.
Corallites various sizes, largest at basal (older) region, smallest towards tips of branchlets. One big corallite at base of branch 10 mm diameter (in the absence of wall, this measurement is taken across columella from point where septum becomes continuous with corresponding costa on opposite sides). Corallites very unequally distant even on same branch – from 10 mm to 40 mm (measured from centers of calices); situated on different sides of branches, sometimes at level on opposite sides of a branch so that septocostae connecting two of them girdle the branch producing marked discordance to their predominantly longitudinal courses.
A corallite usually situated at point of bifurcation of a branch. Older corallites appear protruding slightly because of exertion of thicker septa.
Primary septa as thick as or thicker than intervening loculi: secondaries slightly thinner, both attached to columella; 3 or 4 septa on proximal side of calice very much thickened as to become triangular in appearance. Tertiaries thin, not reaching columella, some of them join the secondaries at their medial ends. Septal edge and surface armed with low, blunt spines, crowded inside the calice, becoming dispersed towards outside.
Septocostae some distance out of calice become subequal in height, but alternation of thick and thin ones quite evident; their courses generally longitudinal up the branches and branchlets, except when they connect corallites at opposite sides when they run obliquely or horizontally across. Edge of septocostae lined with low spinules, those on thicker ones little more prominent and sometimes set in two rows.
Columella circular or oval, an almost solid mass producing numerous tiny tubercles on surface.
