 through lengthwise, as in Fig. 91.

Linear. Laiice- 

 sliaped. 



Oblong. 



Oval. 



OTate. 



Heart-shaped. 



Orbicular. 



Of these the common- 



133. Some leaves taper downwards more than upwards, 

 est forms are the 



Oblanceolate, or Inversely lance-shaped ; that is, shaped like a lance with the 

 point downwards, as in Fig. 94. 



Spatidate ; roundish above, and tapering 

 into a long and narrow base, like the old 

 form of the apothecary's spatula. Fig. 95. 



Obovate, or Inversely ovate ; that is, ovate 

 with the narrow end at the bottom of the 

 leaf, as in Fig. 96. 



Cuneate or Wedge-shaped; like the last, 



Obovate. 



Cuneate or 

 Wedge -ehiiped. 



Oblanceo- Spalulale, 



but with the sides narrowing straight down i^te. 



to the lower end, in the shape of a wedge, as in Fig. 97. 



134, Of course these shapes all run into one another by imperceptible degrees in 

 different cases. The botanist merely gives names to the principal grades. Inter- 

 mediate shapes are described by combining the names of the two shapes the leaf 

 in question most resembles. For example : — 



Lance-linear, or linear-lanceolate, means between linear and lance-shaped. 

 Lance-ohlong, or ohhng-lanceolate, means between oblong and lanceolate in shape. 

 Ovate-lanceolate, between ovate and lance-shaped ; and so on. 



135. Or else a qualifying word may be used, as somewhat ovate, slightly heart- 

 shaped, and the like. Thus, Fig. 92 is ovate in general form, but Avith the base a 

 little notched, i. e. somewhat heart-shaped. It is one of the kinds which depend upon
