biate. It has much of the aspect, but not the bracts and ovaries, of 

 L. Chamissoi. 



L. CONJugialis Kellogg, Proc. Acad. Calif. 2, p. 67, fig. 15. Kel- 

 logg's plant, from Washoe, Nevada, must needs be the same as my L. 

 Breweri, Proc. Amer. Acad. 6, p. 537, and 7, p. 349, which I have 

 since collected in Mariposa County, but never with peduncles longer 

 than the leaves. It is at once known from all American species by 

 the dull dark purple and deeply bilabiate corolla, and nearly obsolete 

 bracts and bractlets. With its near relative in Eastern Asia, L. Maxi- 

 mowiczii, I have already compared it. 



L. oblongifolia Hook., confined to the Northern Atlantic States and 

 Canada, also has a strongly bilabiate (yellowish-white) corolla, and long 

 peduncles. The ovaries vary, even on the same shrub, from com- 

 pletely united to nearly distinct. 



Moxotropa (Hypopitys) fimbriata. Pedalis, inflorescentia 

 excepta glabra ; racemo brevi conferta pub'erula ; bracteis sepalisque 

 obovato-cuneatis spathulatisque fimbriatis parce pilosis ; antheris ma- 

 joribus : flos raro trimerus. — Pleuricospora Jimbriolata Gray in Proc. 

 Am. Acad. 8, p. 394 (Oregon, E. Hall no. 357), not of 7, p. 396. 

 This plant was carelessly misnamed by me : it is totally different from 

 my Pleuricospora, except in the strikingly fimbriate-lacerate bracts, 

 which misled me. There is some approach to this fimbriation in cer- 

 tain Eastern States specimens of M. Hypopitys, to which the present 

 species is nearly related. 



GHIESBREGHTIA, Nov. Gen. Scrophulariacearum.* 



Calyx alte 5-partitus, segmentis linearibus gestivatione ut videtur val- 

 vatis. Corolla ventricosa, bilabiata ; labio postico restivatione exteriori 

 erecto concavo breviter bilobo tubum late campanulatum adaequante, 

 antico requilongo trisecto patente, lobis oblongis planis. Stamina 2, 

 fundo corollaa inserta, rudimentaria nulla : filamenta exserta, divergen- 

 tia : antheras biloculares, loculis mox divergentibus apice confluentibus. 

 Stylus filiformis, e labio postico breviter exsertus : stigma subcapitato- 

 bilobum. Capsula Pentstemonis. Semina numerosissima, oblonga, im- 

 marginata. — Frutex Mexicanus, orgyalis, ramis crebre foliatis, foliis 

 alternis, pedunculis in axillis solitariis ebracteatis unifloris, flore magno
