791 phaneropore — with superficial stomata; with guard cells at the same level as other 
exothecial cells and not sunken in chambers (opposed to cryptopore) [f737, g761, s497]. 
792 phascoid - with a sessile and cleistocarpous capsule; with a bud-like habit as in Phascum 
[f738, g762, s502 
793 phenovariant -- the altered external appearance of an individual as a result of 
environment/genotype interaction; a taxon exhibiting phenotypic plasticity is comprised 
of a range of phenovariants [f1036, g760, $505]. 
794 photophilous - sun-loving [f739, g763, s528]. 
795 photophytic — plants of sunny habitats [f740, g764, s529]. 
796 phyllidium (pl. phyllidia) -- leaf of mosses or leafy liverworts (see caulidium) [f741, g765, 
$510]. 
797 phyllodioicous — nanandrous; with dwarf male plants resting on leaves or tomentum of 
larger female plants [f742, g766, s512]. 
798 phyllotaxy -- the arrangement of leaves on a stem. This is commonly expressed 
numerically as a fraction: the numerator equals the number of revolutions around the 
stem needed to go from one leaf to the leaf attached directly above it; the denominator 
equals the total number of leaves passed in the revolution(s) [f743, g165, s513]. 
799 piliferous — with hair point (see awn) [f745, g431, s873]. 
800 piliform -- long flexuose, hair-pointed (see awn) [f746, g429, s874]. 
801 pilose — with long hairs; e.g., calyptra of some Orthotrichum species [f763, g623, s875]. 
802 pinnate — with numerous, spreading branches on opposite sides of the axis and thus 
resembling a feather [f719, g368, s876]. 
803 pit —- a small depression or cavity in a cell wall [f772, 1024, s955, 1097]. 
804 pitted — having small depressions or holes in the cell wall; sometimes called pores; in 
chlorocysts they are conspicuous as depressions in thickened walls between adjacent cells; 
e.g., Dicranum; pitted dead cells - Pere (see pore) [f773, g398, s954]. 
805 placenta (pl. placentae) -- the phyte, phyte interface, often containing 
transfer cells [f749, g768, 881]. 
806 plane -- flat, not curved or wavy, referring to leaf margins or blade [f750, g-, s882]. 
807 pleisiomorphous (ples-) —- showing primitive characters [f756, g769, 1048, s889]. 
808 pleurocarpous - producing sporophytes laterally from a perichaetial bud or a short 
specialized branch (see cladocarpous) rather than at the stem tip; with stems usually 
prostrate, creeping and freely branched mosses growing in mats rather than tufts [f757, 
g770, 916, s890]. 
808a plica (pl. plicae) —- longitudinal furrow or pleat [f758, g318, s891]. 
809 plicate —- with longitudinal furrows or pleats (plica) [f759, g319, s888]. 
810 plumose -- closely and regularly pinnate; feathery [f760, g321, s893]. 
811 pneumathode - see air-pore [f761, g771, 782]. 
812 polar spore — spore with discernable proximal and distal faces; e.g., spore with 
conspicuous triradiate ridge [f-, g772, s444]. 
813 polycarpic — with two or more sporophytes per perichaetium or perianth; e.g., 
Ptychomitrium lepidomitrium (see polysety) [f764, g776, s894]. 
814 polyembryony - producing more than one sporophyte from a single archegonium, and thus 
sharing a single calyptra (cf. polysety) [f765, g774, s895]. 
815 polygamous -- see heteroicous [f766, g775, s896].
