' 281. Phoradendron juniperinum (Engelm. Mss.): " glabrum, caule articulato di- 

 varicatim ramosissimo ramisque teretibus ; ramulis compressis ; foliis squamseformibus 

 connatis truncatis vix cuspidatis pelvifortnibus 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 Fe, 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." Fendl. — 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, Arceulhobium, and Spiciviscum, Engelm., and of some species of the latter, the name of which I 

 have necessarily changed to Phoradendron. 



" 1. VISCUM, Linn. Flores dioeci campanulali. Fl. masc. Perianthium 4 fidum ; anthera lobis totis 

 adnata multicellulosa, poris plurimis dehiscentes. Fl. fccm. Calyx tubo cum ovario connato, margine inte- 

 gro, limbo obsolete Corolla 4-petala, summo calyci inserta. Ovarium inferum, uniloculare ; ovulo unico pen- 

 dulo : stigma sessile, obtusum, subbilobum. Bacca pulposa, corolla persistente coronata, monosperma. — Fru- 

 tices gerontogei, foliosi, parasitici ; foliis oppositis ; floribus masculis glomeratis terminalibus ; fcemineis in 

 spicas articulatas breves terminales congestis, in qucevis bractea; axilla singulis. 



" I have examined only Viscum album, and based the characters on that species. 



"2. SPICIVISCUM (nov. gen.) [lege Phobadendkon]. Flores diceci glohosi. Fl.masc. Perianthium 3- 

 (raro 2- s. 4-) lobum ; anlheraz lobis imis adnata, transverse biloculares, poris s. rimulis verlicalibus duabus 

 dehiscentes. Fl. fam. Perianthium 3- (raro 2- s. 4-) lobum. Ovarium inferum, uniloculare ; ovulo unico 

 pendulo: stigma sessile obtusum. Bacca pulposa, perianthio persistente coronata, monosperma. — Frutices 

 Americani foliosi s. aphylli, parasitici ; floribus in spicas axillares longiores interruptas articulatas s. abbrevia- 

 tas dispositis, saepe pluribus supra quosvis bracteae axillam rhachidi immersis; bracteis abbreviatis connatis va- 

 ginulam pelviformem formantibus. 



"3. ARCEUTHOBIUM, M. Bieb. Flores dioeci, ovali, compressi. Fl.masc. Perianthium tripartitum, 

 anthera lobis mediis adnata, globosa, uniloculares, rimula transversa dehiscentes. Fl.fozm. Perianthium 

 brevissime stipitatum, bidentatum. Ovarium inferum, uniloculare ; ovulo unico pendulo : stigma sessile coni- 

 cum. Bacca (pulposa?) corolla persistente coronata, monosperma. — Frutices gerontogei et Americani, 

 aphylli, articulati ; foliis ad squamas connatas pelviformes reductis ; floribus axillaribus terminalibusque, mas- 

 culis 1-3, fcemineis singulis.
