608 lanceolate — lance-shaped, in bryology narrow and tapered from near the base; narrowly 
ovate-acuminate [used elsewhere for narrowly elliptical and tapering equally to both 
ends] [f571, g625, s698]. 
609 lanuginose — woolly, tomentose [f574, g1091, s699]. 
610 lateral — at the side; e.g., lateral branches or thallus wings (cf. basal and terminal) [f575, 
g627, 917, s701]. 
611 lax — loose; referring to large thin-walled cells, as well as to nature and spacing of leaves 
on stem, or of stems in a tuft [f561, g648, s702]. 
611a leaf — a photosynthetic outgrowth from the stem; in bryophytes generally consisting of a 
unistratose lamina with or without a multistratose costa (see phyllidium) [f404, g153, 
s625]. 
612 leaf initial — see initial [(537, g158, s627]. 
613 leaf primordium — see primordium [f788, g161, s631]. 
614 leaf trace — a hydroid strand extendind from the leaf costa into the stem; costal hydroid 
strand may be continuous with those of the stem hydrome (true leaf trace) or may end 
blindly in the stem cortex (false leaf trace) [f1003, g164, s1108]. 
615 leiodont — a type of nematodontous peristome found in the Polytrichales that lacks a 
longitudinal wing-like crest on the inner (ventral) surface (opposed to pterygodont) [f576, 
g633, s709]. 
616 lenticular — doubly convex, lens-shaped; e.g., gemma of Oedipodiella; apical cell with two 
segmenting surfaces as in Metzgeria, Fissidens [f577, g646, s703]. 
617 leptodermous — thin-walled; especially leaf cells or exothecial cells [£578, g239, s704]. 
618 leptoid — conductive cell similar to sieve tubes in form and function; found in the central 
strand of stems and setae of some mosses; e.g. , Vobtibsuae di g636, pus 
619 leptome — a phloem-like tissue consisting of leptoids y s [£580, 
g637, s706]. 
620 leucobryoid — having leaves in cross section with inner layer(s) of chlorocyst sandwiched 
between outer layers of hyalocyst; e.g. Leucobryum, Theriotia, (opposed to Sphagnoid; 
see: -oid) [f581, g638, s707]. 
621 leucocyst -- see hyalocyst [(582, g639, s708]. 
622 lid —- see operculum [f681, g198, s1081]. 
623 ligulate — strap-shaped; narrow, moderately long, sides parallel (cf. lingulate) [f586, g128, 
s710]. 
624 limbate --bordered by distinct, elongate and incrassate marginal cells; e.g., Fissidens, 
Syrrhopodon |f588, g388, 640, 873, s711]. 
625 limbidium (pl. lambidia) —- border; differentiated leaf margin; e.g., Fissidens bryoides 
[f589, g-, 5712]. 
626 limb — leaf blade above a differentiated leaf base; e.g. Polytrichum [f587, g957, s713]. 
627 limicolous — growing in mud, margin of pools or lakes [f590, g641, s714]. 
628 limnodophilous — thriving in marshes [f1089, g642, s715]. 
629 limnophilous — thriving in ponds or stagnent water [f591, g643, s715]. 
630 lineage pattern — the direct line of descent from an initial to the mature tissue or organ 
[f585, g8, s716]. 
631 linear — very narrow, elongate with nearly parallel sides; narrower than ligulate [f592, 
g644, s719].
