1. C. limbellata, Nutt. Peduncles several and conji tbose-cliistered at 

 the summit of the stem, several-Jlowei-ed ; calyx-tube conspicuously continued be- 

 yond the ovary, forming a neck to the globulav-urn-shaped fruit ; the lobes ob- 

 long ; style slender; fruit dry. Dry ground; common. May, June. Sterna 

 8' -10' high, very leafy. Hoot forming parasitic attachments to the roots of 

 trees (as shown by Mr. Stauffer). Leaves obovate-oblong, about 1' long. 



2. C. livida, Richards. Peduncles axillary, 3 - 5-Jlowered, shorter than the 

 oval flaccid leaves ; calyx-tube not continued beyond the ovary, the lobes ovate ; 

 ttyk short; fruit pulpy when ripe, red. Shore of Lake Superior, and north-

 summit : disk with 5 glands : style short and thick : stigma capitate-flattened. 

 Fruit fleshy and drupe-like, pear-shaped, the globose endocarp thin. Embryo 

 small : albumen very oily. A low straggling shrub, with alternate short-peti- 

 oled and veiny deciduous leaves ; the small greenish flowers sessile In very short

ORDER 97. LORANTHACE^E. (MISTLETOE FAMILY.) 



Shrubby plants with coriaceous greenish foliage, parasitic on trees, repre- 

 sented in the northern temperate zone chiefly by the Mistletoe and its near 

 allies; which are distinguished from the receding family more by their 

 parasitic growth and habit, and by their more reduced flowers, than by 

 essential characters : represented by 



1. PIIORAl>rVl>RON, Nutt. FALSE MISTLETOE. 



Flowers dioecious, in short and catkin-like jointed spikes, usually several 

 under each short and fleshy bract or scale, and sunk in the joint. Calyx globu- 

 lar, 3- (rarely 2-4-) lobed : in the staminate flowers a sessile anther is borne on 

 the base of each lobe, and is transversely 2-celled, each cell opening by a pore 

 or slit : in the fertile flowers the calyx-tube adheres to the ovary : stigma ses- 

 sile, obtuse. Berry 1-seeded, pulpy. Embryo small, half iinbecded in the 

 summit of mucilaginous albumen. Yellowish-green woody parasites on tho 

 branches of trees, with jointed much branched steins, thick and firm pci>:st< nt
