5. Calycera. 
The type of this genus, Calycera Cavanillesii, was the earliest 
known species of this family, having been described and figured 
by Cavanilles in 1797, under the name of Calicera herbacea. 
The genus is distinguished by the extreme growth of its calycine 
segments, which become expanded into very long spines. In 
this respect it approaches Anomocarpus and Acicarpa. From 
the latter it is distinguishable only by its free achsenia and by the 
much greater length which their spinescent lobes attain ; from 
the former it is distinguished hy the much greater length of the 
peduncles that support the capitula, and by the dififerent form 
of its seeds. 
The genus Gyrnnocladus has been proposed by Dr. Philippi 
(Linnsea, xxviii. p. 705) upon the slender character of the partial 
abortion of the leaves of the involucre and a globose receptacle, 
in a plant which otherwise possesses the habit and all the floral 
• Tl)is plant is represented in Plate 49 b.
