58 PLANTZ FENDLERIANZ. 
LORANTHACEX. 
281. PHorRADENDRON suNIPERINUM (Engelm. Mss.): ‘“ glabrum, caule articulato di- 
varicatim ramosissimo ramisque teretibus; ramulis compressis; foliis squamzformibus 
connatis truncatis vix cuspidatis pelviformibus breve ciliatis; spicis foemineis lateralibus 
oppositis abbreviatis bifloris; floribus bractea inferiore majore et duabus lateralibus in 
cupulam connatis ciliatis fultis globosis 3- (rarissime 4-) lobis.” Engelm. — “ Parasitic 
on the two kinds of Shrub Cedar (Juniperus) which grow on the hills and elevated plains 
about Santa Fé, and on no other tree ; sometimes forming clusters of more than a foot in 
diameter and three fourths of a foot in height. Wherever they are found, they abound on 
many neighbouring trees. The berry is globose, glossy, of a light champagne color, 
with a tinge of red when dried.” /Fend/. —The specimens are all fertile and in fruit; so 
that it is not known whether the plant has the anthers of the genus, but of this there is 
little doubt, as the species is apparently too closely allied to the Phoradendron Californi- 
cum, Nutt., which is ‘‘ parasitic on a Strombocarpus ” (Prosopis).* 
* The genus Phoradendron has recently been briefly indicated by Nuttall (in Jour. Acad. Philad. n. ser. 
1. p. 185), but was unknown to Dr. Engelmann when he communicated to me the subjoined characters of 
Viscum, Arceuthobium, and Spiciviscum, Engelm., and of some species of the latter, the name of which I 
have necessarily changed to Phoradendron. 
“}. VISCUM, Linn. Flores diceci campanulati. Fl. masc. Perianthium 4 fidum; anthere lobis totis
