mersed {immersus)^sis the fruits of many Lichens ; or becldud 

 and nestUng (nidulatis^, as the seeds of the Melastonia in the 

 pulp of the berry. 



When, along with the immersion, it projects a little, it is 

 called emergens, as the fruit of Lecidea lithyrga, from the 

 crust. When a part projects a little, without being directly 

 immersed, it is called prominultLS ; Nervi foliorum suhtus 

 proviinuli. 



When a part of one organ runs downwards on the surface 

 of another, it is said to be decurrent (decurrens). 



When leaves grow in such a manner around the stem, or 

 leaf-stalk, that they seem to constitute one substance with 

 them, they are called perfoliate {perjvliata)^ as in Lonicera 

 caprifolium, Bupleurum rotundifolium, and Jungermannia 

 coalita. Hook. (Mus. Exot. ii. t. 123.) 



When several parts which are sessile, partly cover each 

 other, they are called imbricated {imhi'icatus). 



When a part has a stalk, this is variously denoted, hy pe- 

 tiolatus, in leafy parts ; by pedunculatus and pedicellatus', in 

 blossoms and fruits ; and by stipitatus, in other parts. 



Peltated (peltatus), is a part which has its stalk in the 

 centre, and not on the margin. 



Versatile (versatilis), is a part which rests in such a man- 

 ner on the point of another, that it is inserted in one point 

 only, and is easily put in motion ; for instance, the anthera) 

 of the Grasses and other plants. 



When one part is so loosely bound to another, that it is 

 held only by one small point or thread, but in every other 

 part is loose, it is called basi solutus, as the leaves of Sedum 

 reflexum, saxatile. The opposite of this is adnatus, as in the 

 leaves of Seduni se:j:angulare.
