ASPARAGOPSIS 59 



carriage. Endosperm slight, cartilaginous. Some give useful 

 fibres. 



Closely related to Apocyn., the only absolute distinction being the 

 presence of translators in Ascl. ; otherwise the two sub-orders of each 

 form a corresponding series, and the lower one in each is almost as 

 nearly related to the corresponding one in the other order as to the 

 higher group in its own order. Placed in Gentianales by BH. 



Classification and chief genera (after K. Schumann) : 



I. PERIPLOCOIDEAE (pollen in tetrads; translator spoon- 



like), 

 i. Periploceae : Streptocaulon, Periploca. 



II. CYNANCHOlDEAE(vQ\\\m&\ corpusculum, &c.). 



1. Asclepiadeae (pollinia pendulous on threads): Asclepias, 



Calotropis, Cynanchum. 



2. St'canioneae (pollinia erect or horizontal, 4 in each anther) : 



Secamone (only genus). 



3. Tylophoreae (do but 2 in each, erect): Ceropegia, Stapelia, 



Stephanotis, Hoya. 



4. Gonolobeae (do. but 2 in each, horiz.) : Gonolobus. 

 Asclepias L. Asclepiad. (n. i). ' 160 Am., Afr., esp. U.S. (silk-weeds). 



Herbs with umbellate infls. which spring from the stem between the 

 petioles of the opp. 1. (cf. Cuphea), or above or below this. Two 

 explanations exist, but which is right the evidence available does not 

 show. Either the inn. is axillary to the 1. below it and is 'adnate ' to 

 the stem (cf. Cuphea), or it is the termination of a shoot, and the stem 

 is really a sympodiuin. 



The cuculli of the anthers form little pockets, into which honey is 

 poured by the horn-like nectaries that project from them. Insects 

 walking over the fl. and sipping honey frequently slip their legs down 

 the sides of the gynostegium, and in drawing them up catch in the 

 slit between two anthers and remove the pollinia (cf. family). The 

 process may be watched on A. Cormtti Decne. in gardens.
