FOK FOH.MS AND QUALITIES. 31 



ters, 1. We may consider the situation of parts, in reference 

 to the things whicli surround tliem. We thus call them 

 Jtoating\ submersed, buried. Of these we shall speak on an- 

 other occasion. 2. We may consider the situation of a part, 

 in relation to the organ which lies under it. This is called 

 tlie insertion {hisertio), which is either mediate or immediate. 

 Tlie mediate insertion supposes an intervening substance, by 

 which means a kind of articulation is produced. Such an in- 

 sertion, we observe, for instance, in the labia of some of the 

 Orchidea^, as in Dendrobium, Sw. 



When we mean to signify, generally, that one organ rises 

 out of another, or is inserted on it, we form a derivative from 

 the name of the organ which serves as its support. We thus 

 say, radicaiis, caulinus, rameuSy petiolaris. These denote 

 that which springs from the root, from the stem, the branches, 

 or the leaf-stalks, or which is inserted on them ; Flores pe- 

 tiolares of Turn era cuneiform is, (Tab. V. Fig. 12.) We al- 

 so sometimes form words from the names of both the organs, 

 — from that which is inserted, and that which serves as tlie 

 support. We thus say calyciflorus, calycostemon, (when 

 the filaments spring from the calyx) ; gynandrus, (when the 

 anthers are set upon the pistillum) ; rhizanthus^ thalamic 

 JioruSy (when the flower is set on the receptacle.) 



We also use the prepositions ep'i and hypo, to denote more 

 precisely the insertion. We thus say, epipetahis, liypophyh 

 lus, and so forth. Lastly, [the expressions dorsalis, lateralis, 

 basilaris, terminalis, are important. We signify by them 

 that an organ is inserted,, on the back, on the sides, on the 

 base, or on the summit. 



We also attend to the situation, as it is in the centre, or 

 in the axis, (centralis, axilis), or out of the centre {excentri- 

 cus) ; and also to the tendency towards the centre, or from 

 the centre, (centrifugus, centripetus) ; which terms are espe- 

 cially employed respecting the situation of the cmbryon, and 

 its radicle in the albuminous substance.
