Mostly the protoconch projects a little above the first teleoconch whorl and is slightly down-tilted, but in some species it is strongly exsert
(Clypeostoma salpinx, Pholidotrope gloriosa, Perrinia konos) or slightly sunken below the level of the first teleoconch whorl rendering the apex truncated (Danilia spp., Perrinia angulifera, Vaceuchelus cretaceus).
septa was inappropriate and labor intensive.
33C): Translucent white; diameter 260-280 um; moderately exsert
and relatively globose; worn in all available material; terminal lip shallowly convex; superficial sculpture mostly eroded, but with traces of granulation remaining near suture.
Using low voltage, high-resolution FESEM, we identified four principal crystal forms on the growth surface of exsert
septa sampled from polyps of Galaxea fascicularis.
Diagnosis: Shell small, profile conical with narrowly indented suture; suture level with subperipheral cord; sculpture coarsely cancellate with scale-like projections on spiral cords; columella with a single basal tooth; interior of outer lip thickened and set with ridge-like denticles, that nearest columella largest and separated from basal columella tooth by a U-shaped notch; denticles do not extend into aperture as in-running ridges; umbilical and parietal region covered by glossy inductural callus shield; aperture obliquely tangential to base of last adult whorl; outer lip with low subterminal external varix; protoconch exsert
A female requiring 9 d to exsert
95% of the silks would produce 15% fewer kernels, and leave more than 50% of the exposed silks unpollinated (Fig.
Each day, a new group of plants begins to exsert
silk simultaneously with a second group in its second day of silk exsertion, along with those in their third day, and so on.
0.8 x 0.4 cm, green, tubular, 5-lobed, cuspidate, without rifts, slightly pubescent, with tector trichomes and glandular trichomes, without nectaries; corolla 4.5-5.5 x 1-1.3 cm, red to orange passing pink after pollination, with red to orange fauces, infundibuliform, pubescent, stamens exserted
, dorsal filaments ca.
, each time with fewer legs, claws and/or eye stalks than
Pistillate inflorescences capitate, arranged in 2-5 racemes, each with 4-7 flowers, peduncles to 20 mm long, congested in anthesis, expanded after fertilization, pedicels short < 1mm long; involucre well differentiated 1-2 mm long, sacciform to urceolate in shape, very thick, with 4-5 lanceolated lobes < 1 mm long, bicolor, the basal half darker than the upper; stigma somewhat exserted
, lobed and decurrent; lower part of the perianth consists of 4 lanceolate involucral bracts 1 mm long; indumentum densely short velutinous; no staminodes are present.
Diagnosis: Caudal fin rear margin truncate or slightly emarginate in females, convex or truncate in males, upper and lowermost ray exserted
in some males; dorsal fin 15-17 rays, 3rd spine longest, 1-6% SL longer than 4th spine of males; pectoral fin rays 16-17; anal fin rays 7, fin of both sexes enlarged, pointed, reaching past caudal-fin base; pelvic fins of male much elongated, 1st and 2nd rays enlarged, reaching middle anal fin rays or past anal fin base.
