690 RypBperGc: STUDIES ON THE Rocky MounTAIN FLORA 
O. floribundus Chois ; DC. Prod. 137: 433. 1849. 
A. nyctaginea ovata Morong, Mem. Torrey Club, 5: 146. 
1894. 
In dry soil from Missouri and South Dakota to Wyoming, 
New Mexico and Texas. 
3. ALLIONIA HIRSUTA Pursh, Fl. Am. Sept. 2: 728. 1814 
Oxybaphus jursutus Sweet, Hort. Brit. 1: 334. 1825. 
In sandy soil from Minnesota and South Dakota to Colorado. 
/4. Allionia pilosa (Nutt.) 
Calymenta pilosa Nutt. Gen. 1: 26. 1818. 
Oxvbaphus pilosus Sweet, Hort. Brit. 1: 334. 1825. 
This has been confused with the preceding, but I think it 
amply distinct. So it was regarded by Nuttall and by Sweet. It is 
perhaps nearer related to A. floribunda and Nuttall cites A. ovata 
Pursh as a synonym; but it is well to note that Nuttall describes 
the stem of his species as pubescent, which does not agree with 
Pursh’s plant. A. pilosa grows in dry sandy soil from Wisconsin 
and North Dakota to Texas and Louisiana. 
5. ALLion1A GLABRA (S. Wats.) Kuntze, Rev. Gen. 533. 1891 
Oxybaphus glaber S. Wats. Am. Nat. '7: 301. 1873. 
A rare plant from the arid districts of southern Utah, Arizona, 
and New Mexico. 
/6, Allionia bracteata sp. nov. 
A branched, more or less viscid perennial: stem glabrous 
below, densely viscid-pubescent above, 4-12 dm. high, erect OF 
ascending: leaves subsessile; blades oblong to linear-lanceolate 
or linear, 3-9 cm. long, thick, mostly ciliate, glabrate: leaves © 
the inflorescence elliptic or oblong, to lanceolate, reduced,: less 
than 1 cm. long, more or less viscid-pubescent : involucres often 
numerous in terminal cymes, 10-14 mm. wide; lobes broadly 
ovate, obtuse: perianth white or pale, about 10 mm. broad: fruit 
oblong-obovate, 5—5.5 mm. long, prominently 8-ribbed, apiculate, 
_ constricted near the base. 
This species has been mistaken for A. /inearis and A. a/bida, 
_ but is easy distinguished by the reduced leaves of its inflorescence: 
__ It grows in dry rocky soil.
