inch long. Sepals barely 3 lines long, united below the middle, triangular-ovate, 

 not pointed, in fruit becoming 4 or 5 lines long, and appearing acuminate by the 

 involution of the edges towards the tip. The fructiferous calyx is as widely spread- 

 ing as in A. hastata. Petals about 5 lines long, yellow, tlie nearly truncate summit 

 obscurely erose-crenulate. Fruit depressed and stellariform, as in the genus f^ener- 

 ally, about 5 lines in diameter, very hirsute, usually of 1 1 carpels ; each of them 

 produced on the back into an appendage as long and conspicuous as in many speci- 

 mens of A. hastata {Gen. III. 2. t. 124), but broader and more spur-shaped. Seed 

 as in the other species. — I have not seen A. crenatiflora, Ort. (A. parviflora, Cav.) ; 

 but judging from the description, and from the figure of Cavanilles, our species is 

 to be distinguished by its undivided and not cordate leaves, its glutinous pubes- 

 cence, its longer peduncles, its petals about twice the length of the calyx, the obtuse 

 lobes of the latter, and the manifest dorsal appendage of the carpels. A. pubes- 

 cens, Schlecht. is said to have deeply cordate and sharply acuminate leaves, very 

 acutely acuminate sepals, and muticous carpels. The character of A. lanceolata. 

 Hook. Sf Am. (of which the corolla is doubtfully said to be yellow), accords better 

 with our plant ; but that has the leaves velvety underneath, and the petals (nine 

 lines long) thrice the length of the calyx. 



A. HASTATA, Cav. Diss. 1. t. 11./. 2; Gra^, Gen. III. 2. t. 127; var. depauperata, 

 floribus parvis. — Mountain valleys at the copper mines. New Mexico, and near 

 Santa Cruz, Sonora; Aug., Sept. (895.) — Another small-flowered form of this, 

 or perhaps a different species, was sparingly gathered, in flower only, in valleys of 

 Chiricahui Mountains.

A. Sonora (sp. nov.) : caule erecto petiolisque pilis longis patentissimis hirsutis ; 

 foliis rotundo-cordatis acuminatis subtrilobis crenatis vel duplicato-dentatis 7-9- 

 nerviis supra velutino-puberis subtus mollissime cano-toraentosis ; stipulis caducissi- 

 mis ; floribus laxe paniculatis parvulis ; pedunculis plurifloris ; calycis laciniis ovatis 

 acutiusculis petalis flavis capsulaque puberula apice truncata dimidio brevioribus ; 

 carpellis 7-11 chartaceis mucronatis trispermis. — Hill-sides on the Sonoita, in the 

 nortliern part of Sonora ; Sept. (899.) — Stem 1 to 4 feet high, herbaceous, some- 

 what branched, below densely, above more sparsely hirsute, as well as the petioles, 

 with shaggy and rather stifi' spreading hairs. Leaves 3 or 4 inches in diameter, the 

 deep sinus nearly closed. Floral leaves very small ; the large and loose terminal 

 panicle nearly naked. Peduncles mostly several-flowered, nearly glabrous. Pe- 

 dicels articulated towards the summit. Petals only 3 lines long. Capsule 4 or 5 

 lines long, fully twice the length of the calyx ; the carpels not inflated, their apex 

 dorsally tipped with a short and abrupt mucro.
