the hood, broad ascending, horizontally incurved over the cusps of the anthers; pollen-masses lance-linear, slender, 
slightly curved. 
ry sandy “ washes” of the Virgen River, flowers in June, fruit not seen. Stem 3-5 feet high ; upper leaves 
3}—4 inches long, 1}-14 wide near the base, gradually enlarging downwards, white tomentose on both sites, becoming 
mottled when old. Peduncles about 1 inch, pedicels ? inch in length; flowers about the size of those of A. Cornuti, 
with yellowish green corolla and yellow crown. This species is closely related to two other white-woolly south- 
western species, viz.: A. vestita, H. & A., and A. eriocarpa, Benth. ; the former of which has also long-acuminate [349] 
leaves, but those of the latter are oblong and obtuse at both ends; all these have a short-stalked crown, broad 
ovate truncate or rounded hoods, and a short broad horn 
In A. leucophylla the hoods are largest and fully as long as the anther-tube, rounded and not dentate at the 
upper inner edge ; the broad faleate horizontally incurved horns originate from the base and lower half of the hood ; 
cartilaginous margin of anthers long, obtuse-angled at base; pollen-masses slender, # line or more long; paitile 
glabrous. 
In A, eriocarpa (Hartweg’s original specimen in herb. A. Gray, Remy in Mus. Paris) the hoods are shorter than 
the tube, angular or forming a tooth where the upper and inner margins meet, with two distinct saccate lateral pro- 
jections ; the broad, falcate, horizontally incurved horns originate from the entire midrib of the hood or its upper half; 
cartilaginous margins of the anthers shorter, sharp-angled below ; pollen masses and pistils as in the last. 
In A. vestita (Douglas’ original and Bolander’s specimens in herb. A, Gray) the short hood reaches to the top of 
the anther-tube and has a long horizontal tooth where the upper and inner margins meet ; the broad obtuse horn, 
incurved but more erect and exsert than in either of the allied species, originates from the middle and lower part of 
the tube; cartilaginous margin of anthers short, rounded below; pollen-masses only $ line in length, broad in pro- 
portion and more curved; pistil hairy. 
209. AstepHANUS UraHeEnsis, n. sp. Glabrous, slender, spreading stems from a thick cylindric root; [349] 
linear or filiform leaves; axillary few-flowered umbels ; dull yellow minute flowers; corolla deeply campan- 
ulate with sub-erect cucullate lobes with inflexed points; follicles slender, long-acuminate, smooth ; seeds scaly. 
Drifting sandhills near St. George, the fleshy roots penetrating to a great depth, giving origin just below the surface 
to the slender branches, that twine on adjoining shrubs or swing loosely on the scorching dry sands, Flowers in 
May; fruit in June. 
This very peculiar little Asclepiad has its nearest relatives at the Cape of Good Hope, with one or two stray 
species in the West Indies and South America. The whole plant is of a grayish green color, the thick cylindric root 
light brown ; the branching stems from less than a span to over a foot in length ; leaves about one inch long, { line 
wide ; flov ers about 1-1} lines wide. The corolla is almost closed by the utente inflexed points of the lobes, and is 
glandular papillose internally, so that here these lobes themselves assume the shape and perform the functions of the 
hoods of other Asclepiads, to allure and retain insects to assist in the fertilization of the pistil. The pendulous broadly 
oval pollen-masses are only one tenth of one line long; slender follicles 2-24 inches long; comose seeds usually rough 
by scale-like protuberances.*
