ciliatis subtrifidis. — Var. a. glabriusculum : foliis oblanceolatis seu obovatis 3-nerviis in petiolum sensim attenuatis 
glabris; ramis junioribus puberulis. — /3. pubescens: foliis nt in a., sed puberulis ; ramulis canescentibus. — y. orbicu- 
LATUM (Fh. orhkulatum, Engelrn. PI. Fendl.) : foliis obovato-orbiculatis in petiolum brevein abrupte contractis vix 
trinerviis subpubescentibus. — New Jersey to Southern Missouri and New Mexico, and south to Texas. Var. a. is the 
more northern form, mostly in low woods along water-courses ; in damp places on Ulmus, Algarobia, and also Quercus 
falcata, near New Braunfels, San Antonio, etc.; y. in Texas and Arkansas on dry sterile land, 'bn Quercus nigra and 
other oaks. Flowers, December to March ; fruit'ripens the following winter. 
The nearly related Plioradendron tomentosum, from south of the Rio Grande, has smaller leaves, longer spikes, 
etc. Fhorad&ndron villosum of Oregon has much smaller and spatulate tomentose leaves, etc. 
I take this opportunity to make some corrections and additions to my paper on Viscum and the related genera, 
printed as a note in Plantee Fendlerianee, pp. 58, 59. 
I. VISCUM Bacca globbsa, pulposa, semipellucida, monosperma, corolla persistente coronata. 
II. PHORADENDRON, Nutt. Flores dioeci, globosi. FI. masc. Perianthium 3-(raro 2-s. 4-)lobum: antherse 
loborum basi adnatee, transverssD, biloculares, poris s. rimis verticalibus duabus dehiscentes. Fl.fcem. Perianthium 3- 
(rare 2-4-)lobum: ovarium inferum, tubo adnatum, uniloculare ; ovulo unico pendulo. Stigma sessile, plus minus bilo- 
bum. Bacca globosa, pulposa, semipellucida, monosperma, perigonio persistente coronata. — Frutices Americani, etc. 
* Foliosa; foliis lamina dilatata basi attenuatis ; spicis foemineis plus minus elongatis ex articulis pluribus plurifloris 
constitutis. 
1. PHORADENDRON FLAVESCENS, Pursli^ sub Visco. Vide supra. 
,2. Ph. tomentosum, DC., sub Visco. 
3. Ph. VILLOSUM, Nutt., sub Visco: tomentosum; ramis teretibus ; foliis oblanceolatis s. spathulatis obtusis in 
petiolum brevem attenuatis obscure trinerviis s, subenerviis ; s^Dicis foemineis oppositis s. Verticillatis abbreviatis 2-3- 
articulatis ; bracteis truncatis ; articulis brevibus, inferiore 6-8-floro, superiore 2-floro ; tioribus depresso-globosis 
annulato-carinatis puberulis 3-tIdis. — Wahlamet Woods, Oregon, Nuttall. — Leaves 8-12 lines long, 3—4 lines wide. 
Spikes 3-4 lines long. Flowers 0.5-0.6 of a line in diameter, like those of the two foregoing species de- 
pressed, with an almost annular, ciliate carina. Stigma conspicuously bifid. — The narrow, long, attenuate [213] 
leaves and the short spikes distinguish it from Ph. tomentosum. 
5. Ph. lanceolatum, Engelrn. in Plant. Fendl. 
^ * Squamiosa ; foliis in squamulas connatas pel vi formes reductis ; spicis foemineis ex articulis paucis 1-^-floris 
constitutis. 
6. Ph. Californicum, Nutt. : glabrum ; ramis elongatis strictis gracilibus teretibus ; squamis ovato-lanceolatis 
patentibus basi coiinatis tenuiter ciliatis ; spicis foemineis lateralibus oppositis 3-4-flori3 ; floribus globosis trifidis 
glabris in quovis articulo singulis s. binis cupulse ciliatas immersis ; spicis fructiferis elongatis ; baccis globosis, — 
Sierra Nevada of California, on some species of Strombocarpus, Dr. Gambel. Intermediate and connecting the leafy 
and scaly species of this genus, though properly belonging to the latter. Scales longer than the diameter of the 
branch, patulous. Branches a foot or more long (Nuttall) ; ultimate joints 7-9 lines long ; flowering spikes about 
3 lines, and fruiting spikes 9 lines long. Fruit 3 lines in diameter. Flowering spikes with 2 lateral linear-lanceolate 
ciliate bracts at base, consisting of 3 joints, the lower being always sterile, the two upper ones producing each two or 
by abortion single flowers. In the fruit-bearing spike these joints are in such a manner elongated that the (typically 
axillary) fruit is carried up to the top of the joint, just below the next pair of leaves (or scales). Stigma globose, 
very slightly bilobed. 
7. Ph. juniperinum, Engelrn. in Plant. Fendl. 
III. ARCEUTHOBIUM, M. Bieh. Flores dioeci, ovati compressi. FI. masc. Perianthium 3-(raro 4-)partitum. 
Antherse lobis mediis adnatse, unicellulosoe, rima transversa dehiscentes. FI. foem. Perianthium breviter pedicel- 
latum, 2-(raro 3-)dentatuni : ovarium inferum, tubo adnatum, uniloculare ; ovulo unico pendulo. Stigma sessile, 
conicum. Bacca carnosa, opaca, ovata, compressa, perigonio persistente coronata. —Frutices gerontogei et Americani 
glaberrimi, aphylli, articulati ; foliis squamseformibus in vaginulas pelviformes s. cupuliformes connatis ; floribus axil- 
laribus terininalibusque saepe spicam simplicem s. compositam mentientibus ; fl. masculis 1-3 sessilibus, foemineis 
plerumque singulis brevissime incluso-pedicellatis ; baccis perigonio aucto plerumque discolore coronatis ssepius exserte 
pedicellatis extus carnosis intus viscidis. 
1. A. OxYCEDRi, M. Bieh. : caule ramisque oppositis s. dichotomis compresso-teretibus gracilibus strictis ; 
ramulis ultimis compresso-subquadrangulatis ; squamis triangularibus in vaginulas pelviformes connatis ; floribus 
foemineis in ultimis ramulorum articulis axillaribus terininalibusque in quavis axilla singulis s. binis ; baccis exserto- 
pedicellatis, erectis. — Southern Europe, etc. The specimen before me is from Fiume. — Lowest joints of the ultimate
