LORENTZIA 395 



sympodial, often dichasial, e.g. in Viscum, and the 1. u.su. evergr. and 

 leathery. 



Infl. cymose, the fls. usu. in little groups of 3 (or 2, by abortion 

 of the central fl.). When the fls. are stalked, the bracts of the lateral 

 fls. are always united to their stalks, up to the point of origin of the 

 fl. (see Viscum and Loranthus). Infl. sometimes in spikes, with the 

 fls. on the internodes as well as on the nodes. 



The recept. is hollowed out, and the P springs from its margin. 

 In the Loranthoideae there is below the P an outgrowth of the axis in 

 the form of a small fringe the calycttlus. Some look upon it as a 

 K, many as an outgrowth of the axis; and this is perhaps the safest 

 view. P either sepaloid or petaloid. Fls. $ or unisexual. Sta. as many 

 as, and (as in Proteaceae) united with, the P-leaves. The pollen is 

 often developed in a great number of loculi, separate from one another, 

 though often becoming continuous when mature. Ovary i-loc., sunk 

 in, and united with, the receptacle, the ovules not differentiated from 

 the placenta. Embryo-sacs > one, curiously lengthened (cf. Casuarina). 

 Fr. a pseudo-berry or -drupe, the fleshy part really the receptacle. 

 Round the seed is a layer of viscin, a very sticky substance. [For 

 full details of the many interesting features of this fam., the infl., 

 fl., pollen, development and structure of ovule and embryo-sac, fruit, 

 seed, germination, haustoria, &c., see Engler in Nat. Pfl. and papers 

 by Wiesner in Sitz. k. Akad. Wren, cm. 1894, and Keeble in Trans. 

 Linn. Soc. v. 1896.]
