Claviform

Claviform is the reverse of stalactitic; it is composed of club-shaped parallel rods which adhere by their thin extremities. Examples, brown and black hæmatite.

Two other claviform tentacula arise from the anterior superior part of the mantle [of sea slugs of the genus Doris].

The embryo is roundish, compressed, with a very large, claviform radicle, and two large, foliaceous cotyledons, full of nerves, plaited, depressed, and applied to the radicle; the colour of the embryo is white, except the nerves of the cotyledons, which are rose-coloured.

One zoarial fragment, from sample 2, may belong to Figularia. [...] The elongate-claviform zooecia have long, smooth proximal gymnocysts, extending as much as one-third the zooecial length and continuing as narrow strips along the lateral margins nearly to the distal end.

They vary in shape from filiform (thread-shaped) or claviform (club-shaped) to capitate (with a terminal knob) or moniliform (with a series of knobs).

The claviform (club-shaped) shapes are especially prevalent in the Pyrenees particularly in the Ariege [...], but they are also found in the Dordogne (Lascaux, Gabillou), in Quercy (Saint-Eulalie), and on the Cantabrian coast [...].

Solanum contumazaense [...] Style 10–11 mm long, exerted 4 mm, sparsely papillose below center; stigma claviform, light green.

The claviform comprises a vertical line with a bulge at one side; but unlike the buttocks on the stylized females, the bulge is usually on the middle or the upper half of the 'sign'! It has been suggested that the 'upper bulge' on a claviform instead represents breasts, but this is based on supposedly stylized statuettes from Dolni Vestonice and elsewhere, comprising a rod with two little lumps near the top, and thus on analogies with sites even further away in space and time from the claviforms.
