 subradical leaves linear-subulate ; peduncles elongated, erect ; torus tubular, 

 with a very short limb ; calyx rather obtuse, acuminate. — Eschscholtzia te- 

 nuifolia, Benth. ! I. c.

 Be7ith. 



5. C. hypecoklps (Lindl.) : stems elongated, branched, leafy ; segirients 

 of the leaves short, linear-cuneifomi ; torus tubular, with scarcely any limb : 

 calyx Avith a short acumination. — Eschscholtzia liypecoides, Benth. ! I. c. 



California, Douglnn !—A small and slender plant. Flowers not one-third 

 as large as in C. Californica. Resembles Hypecoum grandiflorum. Benth.

Sepals 2, Petals 4. Stamens numerous: filaments filiform: anthers 

 hnear. Stigmas 2, short and rather thick, sessile. Capsule pod-shaped, fur- 

 rowed, attenuate at the summit; valves thick and coriaceous or almost 

 woody, dehiscing from the base to the apex : placentae filiform. Seeds 

 rather large and numerous, pyriform, smooth.— A branching glabrous shrub ! 

 (the juice not milky ; taste astringent and slightly acid, Nutt.) Leaves 

 rigid and coriaceous, articulated with the stem, lanceolate or oblong, cuspi- 

 date-acuminate, strongly reticulated, denticulate on the margin. Peduncles 

 axillary, 1-flowered. Flowers large, yellow.

 Barbara, Nuttall ! 



9. MECONELLA. Nutt. mss. 



" Sepals 3, somewiiat jjilose. Petals 5-6. Stamens 4-6 : filaments mem- 

 branaceous, dilated upwards : anthers very short, the cells disjoined. Stig- 

 mas 3 (rarely 4), linear, very short, sessile. Capsule pod-shaped, slender, 3- 

 (rarely 4-) valved : valves flat, 1-nerved, dehiscing from the apex to the base, 

 not separating from the placenta;. Seeds numerous, smooth and shining, 

 subglobose.— A very small, annual, glabrous and somewhat glaucous herb. 

 Stems slender, dichotomously branched. Radical leaves in a rosulate clus- 

 ter, spatulate ; cauline ones linear or linear-spatulate, opposite ; the lower- 

 most ternate, entire. Peduncles axillary, filiform, 1-flowered. Flower very 

 small, ochroleucous." 



M. Oregana (Nutt. ! mss.) 



"• Open plains of the Oregon near its confluence with the Wahlamet. 

 May.— Plant 3-5 inches high. Cauline leaves small. Peduncles 1-3 inches 

 long. FloAvers 2-3 lines wide. Petals oblong-cuneifomi, yellow at the base. 

 Capsules linear, 6-10 Unes long. Evidently related to Platystigma." Nutt. 

 —This interesting but humble "pknt seems to stand between Platystemon 

 and Hypecoum, two genera (which notwithstanding their anomalies ought 

 not to be removed from the family,) having apparently little relationship: 

 it agrees with the latter in its definite stamens, and with the former in the 

 foliage and floral envelopes, dilated filaments, &c. The torus is somewhat 

 like that of Chryseis on a very small scale.
