81. Culmal (culmale) having the form of a 

 culm, or the stem of the grass tribe. 



The term is also used for an aggregate fulciment, when the 

 stirplets are considered collectively. 



#.) Stirplet (stirpula) each distinct or separable stirp, rising from 

 the common base of an aggregate fulciment. 



Tubule (tubuhu\ a simple tubular stirplet. 



Culmule (culmulus) a jointed, tubular stirplet. Vide Tube and 

 Culm. 



B. Parts of the stirp. 

 c.)Branch (ramus) is the subdivision of a stirp. 



Branchlet (ramulus) the subdivision of a branch. Tn 



a foliaceous or leaf-like stirp, the primary divisions are 

 better expressed by the term Lacinia, or segments; and the 

 secondary, or subdivisions of the laciniae, by Lacinulee or 

 little segments. 



Rachis (rachis) that part of the stirp from which lateral branches 

 are put out; as in Sertularia frutescens, Ell. Z. T. 6. f. a. 

 Sertularia Pennatula, Ell. Z. T. 7- f- 1. 2. &c. &c. 



Axil (axilla} the angle which a branch forms with the stirp. 

 <?.)Joint (articulus) that part of an articulated stirp which lies be- 

 tween two knots; as in his Hippvris, T. 3. f. 1. 5. Ellis. 



Knot (zeniculum) the juncture of the joints the part by 

 which one joint is united to another; as in Isis Hippuris 

 Tubular ia 'ndivisa. Ellis. When the knot is formed by an 

 intermediate body, distinct in substance or structure from the 

 joints which it connects, it is properly called the 



Inteniode (internodium) as in his Hippuris Isis coccineg, 

 T. 12. f. 5. Ellis. These distinctions between the joint, 

 knot, and internode, are not, however, those which are al- 

 ways observed by authors in other parts of natural history. 

 Vide Mart t/n's Language of Botany, art. Articulus, Nodus, 

 Gcniculum, &c.
