BY A. GRAY. 
The Californian species of this group (in the section Antir- 
rhinastrum) have been somewhat increased in number since the 
revision in the Synoptical Flora. The following key may help 
to a better understanding of them: 
Flowers comparatively large, in a naked spike: lower lip of corolla (with very 
protuberant palate and comparatively short lobes) very much larger than 
the upper: seeds lightly reticulate-favose (truly mature seeds still a desider- 
atum), . A. CouLTERIANUM, Benth. 
_ est spatulate-lanceolate: plants glabrous up to the inflorescence. 
Seeds tuberculate-favose. A. ORCUTTIANUM, n. sp. 
Seeds longitudinally cristate-costate. A. NIVENIANUM, n. sp. 
Scattered : leaves ovate or oblong: herbage glandular or viscid-pubescent : 
seeds longitudinally cristate-costate. 
Leaves petioled, mostly subtending axillary slender-peduncled flowers: 
stems and branches at length diffuse. A. NUTTALLIANUM, Benth. 
Leaves all sessile or nearly so, upper more reduced and bract-like: 
peduncles shorter than the more approximate and racemose flowers, 
often shorter than the calyx: stem erect. A. SUBSESSILE, n. sp, 
Scattered, small, short-peduncled: leaves mostly narrowly linear: plant 
Slabrous: seeds scrobiculate-tuberculate. . A. Kineu, Wats. 
_ Comparatively large but short: seeds undulately cristate and at length ru- 
f0se-tuberculate
