BOTANICAL TERMS. 



19 



Linear : narrow compared with the length (Fig. 44). 

 Oblong : not more than three times as long as broad, and 



with sides inclined to be straight (Fig. 45). 

 OvAii, or Elliptical : not more than twice as long as broad 



(Fig. 46). 

 Orbicular : round, or nearly so (Fig. 47). 



2. Of leaves broadest below the middle. 



Subulate : awl-shaped (Fig. 48). 

 Lanceolate : as in Fig. 49. 

 Ovate : as in Fig. 50. 



Deltoid : about as broad as long, and rather triangular 

 (Fig. 51). 



3. Of leaves broadest above the middle. 



Oblanceolate : the reverse of lanceolate (Fig. 52). 

 Spathulate : like the last, but more rounded at the top 



(Fig. 53). 

 Obovate : the reverse of ovate (Fig. 54). 



WedCtE-Shaped, or Cuneate : like the last, but with the end 

 more flattened and the margins nearly straight (Fig. 55). 



In describing outlines, it will often be necessary to 

 combine terms, as for example : linear-oblong, linear- 

 lanceolate, oblong-ovate, etc., as the case may require. 



Margin. 



Entire : not indented in any way (Fig. 56). 



Serrate : with sharp teeth pointing forward like the teeth of 



a saw (Fig. 57). 

 Serrulate : very finely serrate (Fig. 58). 

 Dentate : with teeth pointing outward (Fig. 59). 

 Crenate : with teeth rounded at the point (Fig. 60). 



A margin may also be dotihly-serrate (Fig. 61), doul)ly- 



denfate, or douhhj-crenate (Fig. 62), when the larger 



teeth are themselves serrate, or dentate, or crenate. 

 Sinuate : deeply wavy (Fig. 63). 

 CiLiATE : with a fringe of hairs. 

 Bevolute : with the edge turned back. 

 Rep AND : like the edge of an expanded umbrella (Fig. 64). 

 PiNNATiFiD : when the edge of a pinnately-veined leaf is very 



deeply lobed (Fig. 65).

(Fig. 66).
