quite as " enervis " as Pringle's Arizona examples. The 

 specimens from Comondu have some of the lower leaves 

 an inch in length, somewhat cordate at base and in these 

 larger leaves the veins are much more evident. The 

 plants from Sierra de la Laguna have a more spreading 

 pubescence and the lower cordate-ovate leaves are two 

 inches in length on petioles half as long. Carlozvrio-Juia 

 cordifolia Gray, at least our example of Palmer's No. 

 224, of 1885, differs very much from the other species; 

 the tube of the corolla is short, but the three anterior 

 lobes are united for some distance above the separation 

 of the dilated posterior lip; the deltoid filaments are much 

 shorter than the corolla and the ovate capsule is almost 

 sessile, the single mature seed is ovate-acuminate. The 

 whole plant is very minutely pubescent and the flowers, as 

 Mr. Rose notes, are arranged unilaterally along the spike. 

 These variances from Dr. Gray's description are so many 

 and so great as to lead to the suspicion of the mixture of 

 plants under the number. 



452. Carlowrightia ? PECTiNATA. Perennial in 

 thick clumps, 2-3 dm. high; branches slender, ramose, 

 geniculate and rooting at the swollen joints wherever 

 in contact with the damp earth, the bark of the older 

 ones white and shreddv, the younger ones apt to be 

 pubescent in lines: leaves glabrous, linear-acuminate, 

 3-4 mm. broad, 25-45 mm. long, becoming revolute : 

 inflorescence, somewhat paniculate-spicate : flowers dark- 

 purple, scattered on the slender branchlets : calyx deeply 

 5-cleft; lobes linear, nearly equal, as long as the corolla 

 tube, a little shorter that -the bracts and longer than the 

 bractlets which are very like them in form: corolla 6-'6 

 mm. long, three times the length of the calyx, almost rotate, 

 the deeply 4-parted limb four times the length of the tube : 

 fllaments pubescent, nearly equaling the corolla; anthers
