The fructification of a plant may afford zfructual 

 or a floral reliquium. 



Repand (repanda) flexuose; but flat, with respect to the sur- 

 face of the stirp Undulated (undulata) bent into folds, 

 which affect also the surface of the stirp &c. $c. 

 The AMBULACRA of the stirp (ambulacra) 

 fl.)Flattish (planiuscula) scarcely elevated into ridges; as in Ma. 

 drepora scabrosa, Ellis. 



Carinated (carinata) forming more or less elevated ridges; 

 as in Madr. ampliata, T. 41. f. 1.2. Ellis. 



Foliaceous (foliacea) rising in leaf-like forms; as in Madr.Lac- 

 tuca, T. 44 gyrosa, T. 51. f. 1. Ellis. 



Spread out (explanata) somewhat foliaceous; but spreading ho- 

 rizontally over the surface of Hie mass. T.63? Madr.cris- 

 tata,T. 31. f. 3. 4. Ellis. 



#.)Straight (recta) running in nearly straight and parallel lines, 

 across the surface of the mass. Madrepora phrygia, T.4S. 

 f. 2. Ellis. 



Flexuose (flexuosd) running in lines more or less bent. Ma- 

 dr epor a meandrites, T. 48. f. 1. Ellis. 



Tortuose (tortuosa) winding in various directions over the sur- 

 face flexuose in a high degree. Madr epor a gyrosa, T. 51, 

 f. 1. 



c.)Simple (simplicia} forming simple ridges only not exhibiting 

 the junction of the margins of the cells. Madrepora phrygia, 

 T. 48. f.2. Ellis. The ambulacra are formed by the unit- 

 ing of the margins which define the apertures; but in a simpk 

 ambulacrum, this union takes place in a single line; in the 



Doubled (duplicata) ambulacra, both margins of the connected 

 cells are evident; giving a double line along the ridges Ma- 

 drepora gyrosa) T. 51. f. 1, Ellis.
