148 PACIFIC COAST PLANTS VASEY AND ROSE. 



leaflets and more glabrous capsules, but in other respects is like the 

 Socorro Island plant. Dr. Palmer says it is very rare in Lower Cali- 

 fornia. 



Two species were collected near Dr. Palmer's station by Xantns in 

 1859 and 1860. Neither of these was Dr. Gray able to definitely de 

 termine on account of poor material. One he refers to ''C. molle, H 



B. K. I," of which but a single specimen was collected. This we have 

 not seen ; it may possibly be the same species, but ours is certainly not 



C. molle. The other species of Xantus was referred to as '•'■Gardios- 

 permum, sp. nov." iVIr. Watson thinks it may be G. tortuosus, although 

 Dr. Gray was doubtful. (See Watson, Bibliographical Index, p. 79.) 

 Bentham's plant was collected by Mr. Hind in 1837, from Magdalena 

 Island, and Mr. Brandegee has collected it from the original station 

 this past season. He did not find it at all on the main-land. Our 

 plant is clearly not this species. G. HaUcacahum, the only other species 

 from the peninsula, is almost glabrous, with smaller flowers. Four or 

 five other species occur in Mexico, but differ in hypogynous glands, 

 foliage, etc. 



The species to which it comes nearest is G. Loxense, H. B. K., from 

 Peru, South America, but this has leaves with petiole 1^ to 2 inches 

 long, the outer sepal half the length of the inner, and with the capsule 

 " pubescenti-hirtelles," etc. 



Dr. Gray referred here, with some uncertainty, a plant from Wilkes's 

 expedition, with perfectly glabrous capsules. Our plant resembles it, 

 but has broader leaflets, longer peduncles, etc.

This may be a new species, but the material is insufficient and for 

 the present it is referred to the above species. It is quite glabrous 

 throughout: the largest leaves IJ inches long, cordate at base, obtuse 

 at apex: corolla small (2 lines broad), with a large purple eye, anther 

 bluish green*
