THE CAPSULE AND ITS KINDS. 279 



rather than a Capsule. Gaertner applies it 

 to Chenopodium, as well as to Clematis, 

 &c. In the former it seems a Pellicula, 

 in the latter a Testa, as we shall hereafter 

 explain. 



Samara is indeed a species of Capsule, 

 of a compressed form and dry coriaceous 

 texture, with one or two cells, never 

 bursting, but falling off entire, and dilated 

 into a kind of wing at the summit or sides. 

 It is seen in the Elm, the Maple, the Ash, 

 Engl. Bot. t. 1C92, and some other plants. 

 This term however may well be dispensed 

 with, especially as it is the name of a genus 

 in Linnaeus ; an objection to which Co- 

 tyledon too is liable. 



Folliculus, a Follicle or Bag, reckoned 

 by Linnaeus a separate kind of seed-vessel 

 from the Capsule, ought perhaps rather to 

 be esteemed a form of the latter, as Gaert- 

 ner reckons it. This is of one valve and 

 one cell, bursting lengthwise, and bearing 

 the seeds on or near its edges, or on a re- 

 ceptacle parallel therewith. Instances are 

 found in Vinca, ^.514, Paonia, t. 1513, 

 and Embothrium, Pot. of New Holland, 

 t.7—10.
