 antherre ovales. Ovula in loculis plurima, rarius pauca. Annuaa, 

 pusilla? vel tenues, saspissime sparsifloros. 



* Flores in dichotomiis subpedicellati. Corolla campanulata, tubo 

 proprio nullo, lobis integerrimis. Folia pleraque tripartita. 



1. G. demissa, n. sp. Divaricato-ramosissima, depressa, glabella; 

 foliis rigidulis, segraentis acerosis ; calyce fere 5-partito, segmentis in- 

 tequalibus lanceolato-subulatis marginibus scariosis, longioribus saspe 

 foliiformibus corollam albam medio 5-lobam adaequantibus ; staminibus 

 inclusis corollae basi insertis ; ovulis in loculis 7. — S. E. California 

 and adjacent part of Arizona, Fremont ; mouth of Diamond River, 

 Newberry (G., Dactyhphylhim, n. sp. in Ives Exped. p. 22); near 

 Fort Mohave, Cooper. Plant 2-3 inches high. Flowers somewhat 

 cymosely crowded, the upper internodes being short : pedicels at most 

 a line long, often almost wanting. Corolla 3 lines long. 



* * Flores sparsi tenuiter saspius longissime pedicellati. Corolla 

 aut breviter infundibuliformis aut fere rotata, lobis integerrimis. 

 Folia 3 - 7-secta, superiora saepius alterna, scabro-hispidula, hirsu- 

 tula, vel fere glabra. Gilia sect. Dactylophyllum, Benth. 



2. G. liniflora, Benth. Folia Spergulce facie ; pedicellis capil- 

 laribus ; corolla (alba) fere rotata, lobis latis calycem bis terve supe- 

 rantibus ; filamentis summo tubobrevissimo insertis basi pubescentibus ; 

 ovulis in loculis 6-8. — Forma major, G. liniflora, Benth., corolla 

 majuscula, lobis lin. 6-4 longis. — California. 



Var. pharnaceoides (G. pliarnaceoid.es, Benth.; Hook. Fl. 2,

 laribus ; corolla (purpureo tincta seu albida fauce luteola) lobis lato- 

 obovatis fauci subcampanulatae cum tubo proprio brevissimo sequilongis 

 seu longioribus ; filamentis sub sinubus insertis basi fere glabris ; ovulis 

 in loculis 3-5. — Forma Chilensis, minor, G. pusilla, Benth. corolla 

 calyce parum longiore. — Var. Californica : corollae lobis amplioribus 

 calycem bis superantibus. G. Jilipes, Benth. Hartw. p. 325. 



4. G. Bolaxderi, n. sp. G. pnsil/ce simillima, differt corolla (cae-
