The thanks of the Academy were tendered to

 of a Linariad considered new — it was found by 

 Dr. Andrews near Puuta de los Reyes. 

 Antirrhinum vexillocalyculatum, Kellogg.-Stem 

 erect, brandling, extremities and branchlets long 

 filiform, pubescent, glandularly pilose, and slightly 

 viscous on all parts, (except stem and leaves be- 

 low,) leaves and branches opposite below, alter- 

 nate above; ovate acute at both ends, 3-nerved, 

 smooth sub-pubescent on long petioles below, 

 gradually diminishing above uutil sessile, subcor- 

 date and very minute. Flowers axillary on short 

 peduncles; calyx 5-parted, upper division very 

 large, leafy, ovate, acute, mucronate 3-nerved, as 

 long or longer than the flowers' lower divisions, 

 two" on each side, linear-lanceolate mucronate 

 (1 -nerved) intermediate lateral divisions smaller 

 or sub-equal, as long as the tube; corolla person- 

 ate, palate very prominent, limb 5-parted, upper 

 lip reflexed, 2-parted, divisions oblong eniargin- 

 ate, lower lip 3-parted, divisions obovate emar- 

 ginate, middle lobe largest, lateral lobes reflexed, 

 tube sub-cylindric, pubescent, gibbous at the base 

 on the lower side, pseudo-spur compressed. 



Stamens 4, inserted into the tube of the corol- 

 la, didynamous, included, filaments twisted com- 

 pressed, kneed at the base, or ascending, glandu 

 larly pubescent above, anthers 2-ceiled, cells 

 parallel before expansion, afterwards reniform or 

 divided, sub-lateral; style filiform;glandular pubes- 

 cent, stigma, 2-lobed, upper longer lobe beaked; 

 eapsnle 2-cHled many-seeded, oblique at base; 

 seeds oblong-ovate. 



This plant is one of the Linariads of Lindley, 

 "'MiiTiinnly known as Figworts, Snapdragons, or 

 Toad-flax &c. This description is taken from a 

 dried specimen, of which we have seen but one, 

 further examinations are needed to determine its 

 > omplete characters, our specimen has no mature 



fruit. The peculiar leafy division of the calyx 

 is aboul one third longer than the flower. 

 the tube aboul half an inch long, il appears 

 t.i be an annual plant, somewhat like flux. 



Dr. K. also reported on the native Millet refer- 

 red to him, accompanied with a drawing and de- 

 scription. 



This specimen furnished by Mr. Dosh of Shas- 

 ta is from the head valley of the Sacramento 

 River. It is remarkable for ils size, being ten to 

 twelve feet high, bearing a head from ten inches 

 to one foot in length, dense clustered, and very 

 prolific. Horses and cattle eagerly devour it. — 

 When we consider the great changes caused by 

 culture, there is no donbt but this will prove a 

 valuable acquisition to the farmer. It furnishes 

 the most wholesome food for birds; it also 

 abounds in farina to such an extent as to be ca- 

 pable of furnishing Hour for domestic and eco- 

 nomical purposes. It is quite similar to the S. 

 Italica and S. Germanica or Italian and German 

 Millets, the stalk with its large swelled joints em- 

 ulates the common Broom-Corn, the ripe grain 

 is shining with a light golden tinge. 



Setaria californica, Kellogg. — Sheaths hirsute 

 and ciliate at upper point where the laminae first 

 embraces the stem; the compound paniculate 

 spike, cylindric, very long, erect, in heaped clus- 

 ters or spikelets; bristles in bundles, about four, 

 bearded upwards, three or four times longer than 

 the seed; valves three, two ovate concave sub- 

 equal },£ to }4 shorter than the seed (outer very 

 small.) 5-nerved, rachis densely hirsute, seed chan- 

 nelled and slightly flattened on one side. 



It is to be hoped flowering specimens will be 

 sent by our friends in that vicinity to enable us 

 to complete the description. 



Dr. K. also exhibited a drawing and specimens 

 of the Dendromieon rigidum, or California Yel- 

 low Rose Tree. 



The comparatively recent discovery of this 

 beautiful flowering shrub in California, has elicit- 

 ed much interest among botanists, as forming a 

 connecting link between the Poppyworts and 

 Rock-roses.
