The species are all American, excepting one in the Sandwich Islands, most numerous near and 

 in Mexico. Of the seven known within the United States four inhabit California ; and n fifth, 

 N. stcnocarpinn, Gray, common on the southern border of Arizona (and well marked by its almost 

 linear capsule) may yet be found near the southeastern frontiers of our State. 



§ 1. Annuals, pubescent or hirsute : flowers terminal and lateral or in the forks, short- 

 pedwicled or sessile : seeds with a thin and translucent close coat. 



1. N. hispidum, Gray. A span to a foot high, repeatedly forked, hirsute or 

 hispid : leaves linear-spatulate, most of the upper ones sessile : liowers lateral and 

 solitary, or 3 to 5 in terminal and one-sided nearly bractless clusters: sepals narrow- 

 linear, hardly if at all broadened upward, shorter tlian the purple corolla : capsule 

 narrowly oblong, 30-40-seeded : seeds nearly smooth. 



Along the Rio Colorado (mostly a low form, with soft pubescence, and occasionally 3 or 4 styles 

 and placentae!), thence east to Texas. 



2. N. demissum, Gray. Dwarf and depressed, commonly 2 or 3 inches high, 

 pubescent, hirsute, or sometimes rather hispid : leaves linear-spatulate, all or most 

 of them tapering into a petiole : ilowers subsessile in the forks : sepals very naiTOw- 

 linear, not at all broader upward, usually much shorter than the bright purple or 

 "crimson" corolla: capgulo ehort-oblong, 10- IG-scodod. 



Interior (loHort region, from the Uio Colorado and tlio Mohnvo, tlirongli W. Arizona, Nevada, 

 and Utah, to Waslnngton Territory. Flowers showy, ns in Conmif.kus, which it much resembles 

 (but that has the styles united into one) : corolla 4 or 5 or even lines long : fihunents very 

 unequally inserted, somewhat subulate. Seeds much larger and fewer than in the preceding. 



3. N. Coulteri, Gray. A span high, diffusely branched, hirsute-pubescent and 

 somewhat viscid : leaves short, oblong-spatulate, the lower tapering into a petiole : 

 flowers short-pedicelled in the forks : sepals with spatulate-dilated tips, not half the 

 length of the narrow funnelform corolla: capsule narrowly oblong, 50- 60-seeded : 

 seeds obscurely wrinkled or pitted. 



No. 4G3 of the Califoniian collection of Coulter ; not since found ; perhaps really collected in 

 Arizona or Mexico. 



§ 2. Suffruticose, silky-rvoolly : flowers clustered. : ovary and styles hirsute. 



4. N. Lobbii, Gray. Depressed and procumbent, forming broad matted tufts ; 

 the older stems woody and rigid : leaves narrowlj-- spatulate or linear, tapering to a 

 nearly sessile base, an inch or two long ; the younger ones Avhito with tlio soft vil- 

 lous wool; tho older becoming naked and thnir margins r('V()Iul(\ morn or less ]ior- 

 sistent: flowers clustererl in the upper axils and at tho summit: sepals very slender, 

 more than half tho length of tho funnelform purple corolla (this half an inch long).
