FOU FORMS AND <;iUALITIES. 



35 



In rows {serialis)^ when the parts follow one another, in a 

 certain order or train. We hence understand what is meant 

 by hi- and tri-seriatus. 



Spiral {spiralis)^ when the parts form a spiral line around 

 the common axis; (Tab. III. Fig. 25, Tab. V. Fig. 1.) 

 TrocMearis is the same (13.), only applied to solid bodies. 

 Gyrosus is used respecting level surfaces, as respecting the 

 fruit of Lichens. 



Rose-like (rosaceits, or rosaceo-congestus), when the parts, 

 by their crowded position, form rosettes, as the leaves of 

 Bryum roseum and Alyssum nebrodense, (Tab. VII. Fig. 5.) 



Radiated (radiatus and radians) , when the parts are 

 placed like the spokes of a wheel.

If no order be observed in the position of the parts with 

 respect to one another, they are called sparse {spar so). If, 

 in addition to this, they are thickly placed, they are said to 

 be crowded (cofiferta, or congesta). But the parts are called 

 aggregate^ when several of them rise from one point : Intri- 

 cate {intricatus)y when the parts are so heaped together that 

 their origin and direction are altogether undistinguishable ; 

 Hyplia Sporotrichi^ Lin. 



If they do not originate in exactly one point, but spring up 

 in the neighbourhood of each other, they are then said to be 

 fasciculated (fasciculata ) ; and conglomerated (conglomei^atd), 

 when they have no peculiar support, but touch one another. 



We also apply the expression compact (coarctatus)^ when 

 the parts, without regard to their origin, stand thick together. 

 We use also the word turf-like (ctespitosus), respecting stalks 

 or branches, which seem to stand thick together, and to grow 

 from one point. 



When plants grow in distinct patches, they are called gre-- 

 garia, in opposition to soUtaria. 



Parts are contiguous (contigims), when their margins seem 

 to meet each other. Continuous (continuus), is a part which 

 seems to be one with some other part, or it is an individual 

 organ which goes on without interruption.
