loides L., and Kraus’ found it also in the families of the Cam- 
panulaces, Lobeliaceew, Goodeniacee, and Stylidiacew, which, 
from a systematic point of view, are each and all connected 
with the Composite. Inulin has, moreover, been proved by 
Kraus to occur in the roots of Jonidium Ipecacuanha, of the 
family of Violacew.* In the family of Composite, inulin pos- 
sesses the function of amylum ;* it is distinguished, however, in 
general from the latter by the following main points.‘ 
Fia. 54 a.—Globular aggregations of crystals (sphzero-crystals) from Radix Inule, by 
keeping fresh pieces ‘of the root for a long time in glycerin. B, cells filled with 
Inulin; 4, separate, strongly magnified aggregations (Sachs). Fic. 52, VI., represents 
such an aggregation in polarized light (Dippel). '

the chlorophyll granules, the stomata cells, as also the starch-sheaths 
and sieve-tubes of plants which form inulin contain starch throughout.
