CALIFOENIAN FIELD NOTES.— I. 



By Ansteuthee Davidson, M. D. 



Calocliortus. 



In the Botany of California Mr. Watson grouped the Mari- 

 posa lilies proper under this heading: 



Flowers and fruit ered on sioid pedicels: flowers open- 

 campanulate: gland usually densely hairy: capsule {except 

 in C. Greenei) narrowly ohlong, with thick lohes, acute, 

 septicidal: sepals often hairy or suhglandular or spotted 

 within: seeds ascending and somewhat turgid, with white 

 loose and spongy miyiutely tessellated testa. 



In this group all the upright Mariposas are included except 

 C. CatalincB, which he has very properly I think separated 

 under the following subdivision. 



Fruiting 



edsflai 



ial, in one row in each cell, with close white testa. 



These definitions, apart from the character of the seeds, 

 which I have not had the opportunity of examining in all the 

 species, separates C. CatalincB on account of the capsule 

 which Watson describes as obtuse and loculicidally dehiscent 

 at the summit. This dehiscence is apparently limited to the 

 part forming the apex of the obtuse capsule and, while well 

 marked, is not peculiar to this species; the same mode of

^ all our South Calif ornian species, unless C. luteus 



7nd clavatus are to be excepted, as having beaks too firm and 

 acute to readily split in this manner. 



In a CatcdinoB the seeds are as described by Watson; flat 

 and horizontal with close white testa. The circular pits that 

 look like nuclei in the centre of the pavement epithelium 

 forming the outer coat of the testa are very distinct. This
