PLANTE FENDLERIANZ. 59 
7 282. ArceuTHosium Oxycepri, 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 Fé, parasitic on Pinus edulis, Engelm. 
283. A. Oxycepri, M. Bieb.? (A. robustum, Engelm. Mss.) Ravines, on the 
lower part of the mountains around Santa Fé, parasitic on Pinus brachyptera, Engel. ; 
March, April, in young fruit.— The same as Oregon, Californian, and Mexican Speci-

1. [P. Catirornicum, Nuit. 1.c. Mountains of California. Perhaps same as the next.] 
2. “P. JuNIPERINUM, Engelm. supra. Santa Fé. 
* « Foliosa. 
3. P. rLavescens (Nutt. 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 Fé (Dr. Wislizenus). A well-known species; flowers half a line in diameter. 
4. “P. oRBICULATUM (sp. noy.): 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. 
5. “P. romMenTosum: 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 faemineis 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 Mimosez, 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 Mimosez. 
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. LanceoLarum (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 ahd 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.
