﻿PLANTS FENDLERIANJE. 59 



f 282. Arceuthobium Oxycedri, M. Bieb. ? (A. gracile, Engelm, Mss.) A slen- 

 der form, or perhaps an undescribed species, as Dr. Engelmann considers it ; but the 

 fruit is unknown. Mountain-sides, around Santa Fe, parasitic on Pinus edulis, Engelm. 

 283. A. Oxycedri, M. Bieb. ? (A. robustum, Engelm. Mss.) Ravines, on the 

 lower part of the mountains around Santa Fe, parasitic on Pinus brachjptera, Engelm. ; 

 March, April, in young fruit. — The same as Oregon, Californian, and Mexican speci- 



" PHORADENDRON, Null. 

 * Aphylla. 



1. [P. Califoknicum, Null. I. c. Mountains of California. Perhaps same as the next.] 



2. " P. juniperinum, Engelm. supra. Santa Fe. 



* * Foliosa. 

 •^ 3. P. flavescens (Null. 1. c.) : " ramis teretibus; foliis obovatis in petiolum attenuatis 3-nerviis, juni- 

 oribus puberulis; spicis folio brevioribus ; bracteis truncatis ciliatis ; floribus in quovis articulo 6 - 10 depres- 

 so-globosis annulato-carinatis parce pubescentibus 3- (rarissime 2-) lobis. (V. flavescens, Pursh.) — On Plata- 

 nus and Ulmus, in the woods of the lower Ohio and from there south ; on Populus, along the Rio Grande 

 below Santa Fe (Dr. Wislhenus). A well-known species; flowers half a line in diameter. 



*- 4. "P. orbiculatum (sp. nov.) : ramis teretibus; foliis orbiculatis s. ovato-orbiculatis breviter et abrupte 

 petiolatis indistincte trinerviis pubescentibus demum glabratis ; spicis folio brevioribus puberulis, etc., ut supra. 

 — On different species of Quercus; on Q. nigra, sterile hills of Arkansas (Engelm.') ; on several Oaks, San 

 Felipe, Texas (Lindheimer). — Leaves on the older branches exactly orbicular, 6 to 10 lines in diameter; 

 young leaves somewhat longer than wide: petioles a line and a half long: flowers half a line in diameter. 



w 5. " P. tomentosum : tomentosum ; ramis teretibus ; foliis obovatis s. oblanceolatis obtusis in petiolum 

 brevem breve attenuatis, senioribus subtus obscure trinerviis ; spicis masculis folium longe superantibus ; brac- 

 teis truncatis, articulis elongatis multi- (15-25-) floris ; spicis foemineis folio subbrevioribus oppositis s. verti- 

 cillatis ad apicem caulis paniculatim congestis, articulis brevioribus sub 8-floris ; floribus immersis depresso- 

 globosis annulato-carinatis puberulis 3- (rarissime 4-) lobis. (V. tomentosum, DC. Prodr. 4. p. 670.) — On 

 Algarobia and one or two other Mimoseas, near Rinconada, Northern Mexico, Dr. Gregg. — No doubt the 

 same as De Candolle's plant, which was collected in Northern Mexico by Berlandier, also on Mimoseae. 

 Leaves an inch or one and a quarter long, and half as wide. Sterile spikes one and a half to two and a half 

 inches long : female spikes only about an inch long : flowers very similar to those of both the foregoing spe- 

 cies, and of the same size or rather smaller. Fruiting spikes slightly elongated, an inch to an inch and a half 

 long : berries one line and three fourths to two lines in diameter. 

 • 6. "P. lanceolatum (sp. nov.): glaberrimum ; ramis teretibus; foliis lanceolatis elongatis subfalcatis 



obtusiusculis in petiolum brevissimum sensim attenuatis 3- 5-nerviis ; spicis masculis folio brevioribus ; bracteis 

 triangularibus connatis ; articulis 8-18-floris; floribus immersis globosis 3- (rarius 4-) lobis. — On 'Live- 

 Oak,' Rinconada, Dr. Gregg. — Leaves 3 inches long, half an inch wide : sterile spikes an inch and a half to 

 two inches long. Flowers less than a line in diameter; distinguished from those of the foregoing species by 

 being destitute of the horizontal edge, and entirely glabrous, as is the whole plant. Anthers very distinct, sim- 

 ilar to the common form of two-celled anthers, opening longitudinally, while in the other species they open by 

 two pores. — Apparently near V. Schiedeanum, DC, but distinguished by the terete branches." Engelm. Mss.
