FOR FORMS AND QITALITIES. 35 



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

 certain order or train. We hence understand what is meant 

 by bi- and tri-seriatus. 



Spiral (spiralis), when the parts form a spiral line around 

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

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

 Gyrosiis is used respecting level surfaces, as respecting the 

 fruit of Lichens. 



Rose-like {rosaceus, 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. 



38. 



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

 respect to one another, they are called sparse (sparsa). If, 

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

 be crowded (con/erta, or congesta). But the parts are called 

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

 cate (intricatus), 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 (fascicidata)\ and conglomerated (conghmerata), 

 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 (caspitosus), 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-- 

 garitp, in opposition to soUtaria. 



Parts are contiguous (contiguus), when their margins seem 

 to meet each other. Continuous {contimms), is a part which 

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

 organ which goes on without interruption.
