86 PROCEEDINGS OP THE AMERICAN ACADEMY 



LO&SELTA Linn. § Giliopsis. Flores paniculati vel sparsi, ebrac- 

 teati. Corollas lobi subcuneati, apice eroso-truncati vel subtridentati. 

 Folia angustissiraa nuda. (Ovula in loculis 8-10. Semina ut in 

 spec, propriis exalata!) 



LcESELiA TENUiFOLiA. E basi frutescente multicaulis, spithamasa 

 ad pedalem, glabella ; ramis gracilibus apice laxe paucifloris ; foliis 

 fere acerosis cuspidato-mucronatis integerrimis vel inferio<ibu3 sub- 

 liuearibiis paiici-pinnatipartitis, lobis subulatis ; calycis lobis subulatis 

 tubo dimidio brevioribus ; corolla punicea tubuloso-infundibuliformi 

 (pollicari), tubo lobis 3-4-plo longiore ; genitalibus longius exsertis. — 

 Northern borders of Lower California, Tantillas Mountains, especially 

 at the entrance of the Great Cafion, "W. Dunn, E. Palmer. Longer 

 leaA'es an inch long ; the upper gradually reduced to small subulate 

 bracts, but none at the base of the calyx. One lobe of the corolla 

 separated from the others by deeper sinuses ; the long capillary fila- 

 ments (which are inserted low down on the tube) more or less de- 

 clined to that side, and their summits a little incurved. 



LcESELiA EFFUSA. Spithamaea ad pedalem, e radice annua laxe 

 ramosissima, glabella ; ramis ramulisque paniculato-floribuudis gracil- 

 limis rigidulis ; foliis omnibus fere filiformibus mucroue apiculatis 

 integerrimis (radicalibus evanidis) ; calycis dentibus brevibus latis ; 

 corolla brevi-infuiidibuliformi purpurea, tubo cah'cem paullo superante 

 lobis inasqualibus baud longiore; genitalibus (sat declinatis apice incur- 

 vis) corollam parum excedentibus. — Tantillas Mountains, borders of 

 Lower California, Dr. E. Palmer. Stem sometimes as if lignescent 

 at base; but the root plainly annual. Leaves from half to a quarter 

 of an inch long, or less. Pedicels sometimes as long as the flowers, 

 mostly shorter than the calyx. Corolla (" pink," but in the dried 

 specimens violet-purple) barely half an inch long, the limb rather 

 ample and spreading, one or two lobes rather smaller and more sep- 

 arated. Capillary stamens inserted low on the tube of the corolla. 

 Ovules, seeds, &c., as in the preceding. 



Except for the declined stamens and some inequality of the corolla, 

 these two species would be referred to Gilia, the former to the section 

 Ipomopsis, the latter to Eugilia. But they accord with Lceselin, 

 except in the total absence of dilated bracts, which, considering the 

 case of Gilia, cannot be the generic character. The seeds do not 

 supply a character. These in Loeselia, as remarked in the yet un- 

 published portion of the Genera Plaiitarum by Bentham and Hooker, 

 develop mucilage wlieu wet; the mucilage-cells are underneath a
