PLANTS FROM BAJA CALIFORNIA. 129 



the sepals are four tooth-like processes, alternating with 

 the four petals and apparently in the same whorl; the 

 two upper petals are somewhat longer than the lower. The 

 irregularity of the flower is apparently caused by the elon- 

 gating stipe of the ovary developing to the lower side, lifting 

 and passing beneath the inferior tooth-like process that 

 embraces it as an oblique ring; this tooth longer than the 

 upper and four times longer than the lateral ones, becoming 

 also superior. The stamens are six, gradually tapering, 

 from a somewhat bulbous base, not abruptly as in the 

 figure, and in the numerous flowers examined, no trace of 

 staminodia has been found. The petals are all curved 

 to the upper side. — San Gregorio. 



Oligomeris subulata Bois. — Magdalena Island and 

 throughout the whole region traversed. 



Helianthemum nutans. Densely and minutely stellate 

 pubescent throughout: stems woody, much branched, about 

 9 inches high: leaves linear, obtuse, slightly tapering to the 

 base, 5-7 mm. long, 1mm. wide: pedicels solitary from op- 

 posite to the axils of the upper alternate leaves, recurved, 

 14 mm. long, jointed near the base: inner sepals 6 mm. 

 long, ovate, acute, the outer linear, half as long: petals 

 slightly exceeding the sepals, broadly caneate, acute: 

 stamens about 20: seeds covered with white strap-shaped 

 papilhe. 



The lower portion of the small bushes is covered with 

 fascicles of axillary leaves, that joersist after the primary 

 ones have fallen, and give to the plants an cricoid appear- 

 ance. — Very abundant in rock}^ soil about the plains of San 

 Julian . 



loNiDiUM POLYGAL^FOLiUM Yent. /. llneave Torr. — Santa 

 Margarita Island.
