 hairs. EUlform = thread-like. Acicn^r (fig. 264). Linear (fig. 265).

 having three or more angles. Deltoid = like the Greek letter A. Obovate 

 (fig. 262). Cuneate = wedge-shaped and attached by its point to the petiole. 

 Spathulate (fig. 261). Cordate (fig. 257). Obcordate (fig. 263). Reniform 

 (fig. 258). Auriculate, when the base of the lamina assumes the form of 

 two ear-like processes (auricles). Sagittate (fig. 259). Hastate (fig. 260), 

 Ensiform = sword-shaped. Falcate = sickle-shaped. Peltate = shield-like 

 (as m'^Tropaolum).

ginate (fig. 269-1). Mucronate = ending in a special pointed prolongation 

 of the mid-rib. Apiculate = ending in a short small point.
