folds to nearly or quite the rotate. In one the petals are 

 comparatively narrow, their margins not meeting when the 

 flower is fully open; in all the rest they are broad, and over- 

 lap each other when expanded. 



The torus does not appear to have been at all carefully 

 examined by any of the authors who have written upon the 

 genus. It has commonly been described as being either 

 simply turbinate, or as dilating to a broad rim. The true 

 state of the case is this: the upper portion has always two 

 distinct rims, the inner always short, thin, scarious, nerved 

 or nerveless, and usually erect. Outside of and below this 

 is a separate one, generally more herbaceous, aud this in 

 two or three species is very broad and conspicuous; but in 

 others it appears as a mere fleshy ring, or is more rarely 

 thin and hyaline, like the inner one. 



Due attention has been given to the characters of the 

 seed; bat these have not been found to be of greater value 

 than those of the corolla and the torus. As a rule the seeds 

 are perfectly globular, with a black or very dark brown 

 testa, which, under a good lens, appears scrobiculate in all 

 the species. The coarser and usually angular reticulation 

 of lighter color, which marks the seeds of most species, is 

 wholly wanting in those of a new one from the Mohave 

 Desert, while in an old one not of late recognized as a spe- 

 cies, but now restored, this appendage takes not the form of 

 reticulation, but rather of scattered, pyramidal, or often 

 flattened, strap-shaped processes, which in some specimens 

 are so dense as to entirely hide the testa and give the seed 

 the appearance of a burr. The seeds of a new species from 

 the peninsula of Lower California are exceptional in being 

 perceptibly elongated and having an apiculation at each end. 

 Those of the new one from the Mohave are peculiar not only 

 in their lack of reticulations or other apppendage, but in 

 being deeply pitted and of an ash-gray color. 



The Eschscholtzias are far from being always smooth. 

 Half the species are more or less hairy or scabrous; but all
