 Brit, (mistletoe) is a semiparasitic shrubby evergr., growing on apple, 

 hawthorn, oak, &c., and drawing nourishment from its host by suckers. 

 It is repeatedly branched in a dich. manner, the central stalk usu. 

 ending in an infl. Each branch bears two green leathery 1., and 

 repres. a year's growth. The unisexual dioec. fls. are in groups of 

 three. No calyculus. Sta. completely fused to the P-leaf. Pollen- 

 sacs very numerous. Ovary as usual. The fls. secrete honey and 

 are visited by flies. Pseudo-berry. The layer of viscin prevents the 

 bird that eats the berry from swallowing the seed, which it scrapes 

 oft" its bill on to a branch, where it adheres and germinates.

 which repres. modified infls.; the stem is usu. regarded as a sympo- 

 dium, each axis in turn ending in a tendril, but there has been much 

 argument upon the subject. The tendril may attach itself by the 

 ordinary coiling method, or may be negatively heliotropic and thus 

 force its way into the crevices of the support : in these crevices the 

 tips of the tendrils form large balls of tissue, the outer parts of which
