1. D. palustris L. A shrub 6 to 15 dm. high, with white and soft very brittle 
wood: fibrous bark remarkably tough (used by the Indians for thongs, whence the 
popular name),—Damp rich woods, extending from the northeastern states into 
eastern Texas, 
LORANTHACEZA. (MISTLETOE FAMILY.) 
Shrubby plants, with coriaceous greenish foliage, parasitic on trees, 
represented in the north temperate zone chiefly by the mistletoe and 
its near allies; distinguished from the next family more by the para- 
sitic habit and more reduced flowers than by essential characters. 
1. Razoumofskya. Authersa single orbicular cell: berry compressed, fleshy: 
leaves scale-like (or none), connate. 
2, Phoradendron. Anthers 2-celled: berry globose, pulpy: leaves foliaceous. 
1. RAZOUMOFSEYA Hofim. 
Glabrous diccious parasites on conifers, with rectangular branches, 
flowers solitary or several in axillary or terminal spicate or paniculate 
clusters, mostly compressed calyx (staminate usually 3-parted and 
pistillate 2-toothed), obicular anther-cell opening by a circular slit, and 
fruit on a recurved pedicel. (Arceuthobium Bieb.) 
1. R.vaginata (Kichler.) Kuntze. Leafless: stems quadrangular, but branches 
round, compressed, the articulations bearing a sheath which is 2-toothed at apex: 
Howers 2, opposite, sessile in the sinus, (Arceuthobium vaginatum Eichler, 4, cryp- 
topodum Eng.)—From Texas to central Mexico. 
2. PHORADENDRON Nutt. (Fase MISTLETOE, ) 
Yellowish green diccious parasites on the branches of trees, with 
jointed much-branched stems, thick and firm persistent leaves (or only 
scales in their place), short catkin-like jointed wxillary spikes (usually 
several to each short fleshy bract or scale and sunk in the Joint), 
3 (rarely 2 or 4)-lobed globular calyx, anthers sessile on the base of the 
calyx-lobes and opening by a pore (except in No. 3), sessile obtuse 
stigma, and a semi-transparent berry crowned with the persistent 
sepals, 
Leaves foliaceous, mostly dilated upward from a narrow base. 
1. P. flavescens Nutt. (AMERICAN MISTLETOR.) Stems round, often 8dm, long: 
leaves oblanceolate to ovate or orbicular, obtuse, 1.5 to 5 em, long, yellowish, 3-nerved, 
at last glabrous: staminate spikes shorter than the leaves, 3 to 7-jointed, with fra- 
grant flowers: berries white, 4 mim. in diameter.—From Eagle Pass to central Texas. 
Reported on Ulmus, Querens, and Prosopis. Var. VILLoSUM Eng. has small or middhe- 
sized orbicular tospatulate leaves which are permanently pubescent or tomentose, and 
slender rather short spikes. —Extending into Texas fromthe west and northwest. 
2. P. Bolleanum Eichler. Puberulent,at length glabrous: leaves spatulate to 
linear, 12 to 24 mm, long, nerveless, obtuse: staminate spikes of two 6 to 12-flowered 
joints; the fertile a single 2-flowered joint: fruit white, 3 mm. in diameter.—From 
the Guadalupe mountains to E] Paso, on Juniperus occidentalis. 
* * Leaves reduced to short mostly connate scales : spikes opposite, mostly few-flowered. 
3. P. Californicum Nutt. Pubescent or at last glabrous: branches round, slender, 
3 to5 dm. long: seales broadly ovate, aente, spreading: staminate spikes of 2 or 3 
(rarely 5) flower-bearing joints, each with 2 to 6 ovate-subglobose tlowers, anther 
cells opening by a slit; fertile spikes with nearly as many joints which are elongated
