B. Leaves oblong, pale green beneath; fruit globose, constricted above the line at 



which the perianth joins it. W. E. C. umbellata 



BB. Leaves linear or narrowly lanceolate, or those of the main stem oblong, glaucous 



beneath; fruit ovoid-oblong, constricted at the line at which the perianth joins it.

short. E. C. livlda (GREEN COMANDRA) 



LORANTHACEAE (MISTLETOE FAMILY) 



Herbs or shrubs, green or yellowish- or olive- or brownish-green,

AA. Shrubs, parasitic on Quercus or Juniperus or Libocedrus; anthers 2-celled ; 

 berry sessile ; inflorescence bracted. PHORADENDRON (p. 78) 



RAZOUMOFSKYA (SMALL MISTLETOE) 



Herbs, perennial, parasitic on branches of conifers, fleshy, small or minute, 

 glabrous; branches 4-angled. Leaves scalelike, opposite. Flowers 

 solitary or several together in the axils of the scales. Perianth of staminate 

 flowers 2-4-parted; stamens usually i on each perianth lobe; anthers 

 sessile. Perianth of pistillate flowers with 2-parted limb. (Honor of 

 A. Razoumofski, a Russian botanist.) 



A. On Pinus contorta or Pinus flexilis; staminate plants 5-10 cm. high, 0.5-2 mm. 



thick at base; pistillate plants much smaller; staminate flowers dichotomously 



paniculate, nearly all terminal on pedunclelike joints. W. E. R. americana 



AA. On trees other than those in A; staminate flowers nearly all axillary, forming 



simple or compound spikes. 

 B. On Pinus ponderosa; stems 5-13 cm. high, 4-5 mm. thick at base. W. 



R. campylopoda (SNAPPERS) 

 BB. On conifers other than Pinus; stems 0.8-4 cm. high. C. E. R. douglasii 



PHORADENDRON (MISTLETOE) 



Shrubs, parasitic on trees, yellowish-green or olive-green; twigs brittle, 

 usually jointed. Leaves flat, coriaceous. Flowers small in bracted spikes. 

 Perianth 2~4-lobed. Anther i at the base of each perianth lobe, sessile, 

 transversely 2-celled. Ovary inferior ; stigma entire. (Gk. phor = a 

 thief, dendron = a tree ; because it is parasitic on trees.)
