Involucel, (dim. of involucrum, a wrapper), “a secondary involucre, usually not containing more than one or two flowers” (Lindley); “a secondary partial involucre” (Jackson); “a secondary involucre, as that of an umbellet in Umbelliferae” (Fernald 1950); the epicalyx, or external series of envelopes beyond the calyx, as in Malva” (Lindley): involucellum,-i (s.n.II), abl. sg. involucello, nom. & acc. pl. involucella, dat. & abl.pl. involucellis; see epicalyx;

- fructus (achaenium) involucello persistente arcte inclusum saepeque parietibus suis plus minus adnatum, fruit (an achene) closely enclosed by the persistent involucel and often more or less adnate by its own walls.

- involucellum carnosum, urceolato-depressum, obscure dentatum, intus setis plumoso-barbatis densissime pulvinatis vestitura (B&H), the involucel fleshy, urceolate-depressed, obsculely dentate, inside clothed with plumose-bearded, very densely pulvinate bristles.

- capsula (a nobis non visa) 3-locularis, involucello aucto carnoso inclusa (B&H), the capsule (by us not seen) 3-locular, included in an enlarged, fleshy involucel.

- involucellum urceolatum, truncatum, 6-denticulatum (B&H), involucel urceolate, truncate, with 6 small teeth.

- involucelli foliolis indivisis stipulisque linearibus (F. Mueller), the leaflets of the involucel undivided and the stipules linear.

- involucelli triphylli foliolis minutis oblongis (F. Mueller), the leaflets of the three-leaved involucel minute, oblong.

- involucelli foliolis lineari-subulatis calyce parum brevioribus (F. Mueller), the leaflets of the involucel linear-subulate, somewhat shorter than the calyx.

- spicula terminali solitaria involucellum diphyllum superante (F. Mueller), with the spikelet terminal, solitary, over-topping the two-leaved involucel.

- involucro involucellisque 5-6-foliolatis (Boissier), with the involucre and involucels 5-6-leafletted.

- involucro involucelloque nullis (Boissier), with the involucre and involucel none.

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
