 this may be 



Coalescent (coalescentes) cohering with one another in distant 



parts only; as in Madreporaflexuosa, T. 31. f. 5. Ellis. 

 &.)Alternate (alterni) coming out regularly, one after another, from 

 different sides of the main stirp ; as in Sertularia Filicula* 



T. 6. f. C. c. Ellis. Alternate branches may be 



Pinnatedly-alternate (pinnate-alt erni) arranged alternately on 

 the two opposite sides of the main stirp ; as in the species 

 just referred to or 



Circularly-alternate (circulatim-alterni) arranged in a spiral 

 manner about the stirp rising by steps round the stirp 

 This disposition of the branches, a common one in plants, 

 is, perhaps, rare in the present bodies; we have a speci- 

 men of fossil millepore coral, however, in which it takes 

 place. 



Opposite (oppositi) placed over against each other opposite 



branches may be 



Pinnatedly-opposite (pinnatc-oppositi) arranged on two sides 



of the stirp; each branch being opposite to another or 



Decussatedly-opposite (decussatim-oppositi) arranged, cross- 

 wise, in four rows; each pair of opposite branches being 

 at right angles with the pairs next above and below it. 

 c.)Scattered (spar si} neither opposite nor alternate without any 



regular order. Crowded (conferl'i) Verticillate (verti- 



cillati) Fascicled (fasciculati} &c. &c. &e. All the 



terms employed in Botany to distinguish the situation, direc- 

 tion, and structure, of the branches of a plant, are applica- 

 ble to the branches of an arbuscular fulciment. 



The RACHIS of the Stirp (Rachis) 



Even(/<mY)with an even surface Striated (striata) marked with 

 slender lines. Wrinkled (rugosa) Nodous (nodosa) &c 

 &c. &c.
