short, divaricate, rigid ; leaves opposite, elliptical, 3-4" long, very shortly 

 petioled, subtomentose, with very rarely 1-2 small teeth toward the apex ; 

 flowers in small terminal umbels on very short (1-2") lateral branchlets ; fruit 

 truncate-globose, with 3 prominences, the pedicel 3-4" long. — Very near C. 

 cuneatus, Nutt. New Mexico and Northern Mexico ; Southern Utah, (Palmer.) 

 Rhus glabra, L. South"ern Utah, (Palmer.) 



Page 63. Hosackia pubeeula, Benth. Grayh 8yn., I. c, p. 349. Per- 

 ennial, slender, erect, 6'-l° high, minutely appressed-puberulent ; leaflets 

 ^ 3-6, on a short rachis, linear, lanceolate or oblong ; peduncles exceeding the 

 leaves, 1-4-flowered, the bract 1-3-foliolate ; flowers 6" long, turning purple ; 

 calyx-teeth attenuate, as long as the tube ; pod linear, 1' long, straight or 

 nearly so. — Dr. Palmer's specimens have the peduncles 1-2' long, but the 

 petiole is wholly wanting, the apparently palmate leaflets oblanceolate, spatu- 

 late-oblong, or the lowest obovate. Other specimens from New Mexico, 

 (Palmer, 1869,) and from the Rio Verde, Arizona, (Dr. Smart,) tend to unite 

 H. Wrightii with this species. Southwestern Texas, Arizona, and Mexico ; 

 Southern Utah. 



Page 64. Dalea lanata, Spreng. (Z>. lanuginosa, Nutt.) Decum- 

 bent, canescently tomentose throughout, the stems 1-3° long from a bien- 

 nial or perennial root ; leaflets 4-6 pairs, obovate-cuneate, emarginate, 3-6" 

 long, 2-3" wide ; bracts ovate, abruptly long-acuminate ; spikes usually 

 opposite to the leaves, 2-3' long, on moderately long peduncles, many- 

 (30-50-) flowered ; calyx-teeth plumose, subulate, broad at base, equaling 

 the tube ; petals deep-purple, wings and keel oval, nearly equal, the banner 

 broadly cordate, a little the longer, 2-3" long, but httle exceeding or twice 

 longer than the calyx ; pod small. — From Nebraska, (James,) Arkansas and 

 the Indian Territory to Western Texas, New Mexico, and Northern Mexico;

 spines often 3" long, sharp and stout, subrecurved ; leaflets elliptic or ob- 

 long, i-1' long; peduncles and the short-crowded racemes hispid with 

 straight glanduliferous hairs ; calyx finely hispid, the teeth subulate-lance-
