THE STELLATE TRIBE. 



In hedges and thickets, throughout Europe and northern Asia, from 

 the Arctic Circle almost to the tropics, and now spread over North 

 America. Abundant in Britain. Fl. the whole summer, and often in 

 autumn. Slender or short varieties, less hispid, and with smaller 

 fruits, have been distinguished under the names of G. Vaillantii (Eng. 

 Bot. Suppl. t. 2943) and G. spurium (Eng. Bot. t. 1871), but the latter 

 name is also given to luxuriant forms of the corn G. 



10. Corn Galium. Galium tricorne, "With. (Fig. 473.) 



(Eng. Bot. t. 1641.) 



Yery near the cleavers G., but a 

 smaller plant, seldom above a foot long, 

 the leaves shorter, the peduncles shorter 

 than the leaves, with only 1, 2, or 3 

 flowers, the pedicels of which are rolled 

 back and thickened after flowering, and 

 the fruit is granulated only, without 

 hooks or bristles. 



A much more southern plant than the 

 cleavers G., very common in waste and 

 cultivated places in the Mediterranean 

 region, and eastward to central Asia ; 

 becomes a cornfield weed in central Eu- 

 rope, and as such extends over most 

 counties of England, but disappears in 

 the north. Fl. with the corn, or some- 

 -p. ^n times later, on the stubble,

III. ASPEEULE. ASPERULA. 



Differs from Galium only in the shape of the corolla, which tapers at 

 the base into a tube at least as long as the lobes, and often several 

 times longer. 



The species are less numerous than those of Galium, and the geo- 

 graphical range is not so extensive, being limited to Europe, northern 

 Africa, northern and central Asia, and Australia. 



Leaves lanceolate, about 8 in a whorl. Fruit hispid ... 1. Woodruff A. 

 Leaves linear, opposite or 4 in a whorl. Fruit small, glabrous 2. Small A.
