Detmaria gracilis, Cham. & Schlecht. Stems very lax, from a 

 perennial root, glabrous throughout : leaves cordate or deltoid-ovate, 

 acute : inflorescence much branched and diffuse : sepals thin, nearly 

 nerveless, acute or acutish, 1^ to 2 lines long. — San Luis Potosi- 

 (130 Schaffner, in part) ; Guanajuato (Duges) ; also 57 Parry & 

 Palmer, 21 and 2659 Bourgeau, 706 (?) and 710 Coulter. 



Drtmaria Fendleri. Annual ; the erect or ascending stems 

 and the petioles usually more or less pubescent : leaves broadly sub- 

 reniform-cordate or the base sometimes truncate, acute or shortly 

 acuminate : flowers on short pedicels and more or less fascicled, the 

 pubescent and somewhat rigid sepals long-acuminate, distinctly 1-3- 

 nerved, about 2 lines long. — From New Mexico and Arizona to 

 Central Mexico ; 60 Fendler (B. cordata, Gray, PI. Fendl. 13) ; 

 866 Wright, also Thurber and Bigelow (Z>. glandulosa, Gray, PI. 

 Wright. 2. 18 ; Torrey, Pacif. R. Rep. 4. 70, and Bot. Mex. Bound. 

 37) ; Greene, 42 Rusby, and 510 Lemmon ; near San Luis Potosi, 

 130 Schaffner, in part; Valley of Mexico, 552 (?) Bourgeau. Two 

 other species of this group, more or less confounded with the pre- 

 ceding, may be characterized as follows : — 



Drtmaria villosa, Cham. & Schlecht. {D. pahistris, Cham. 

 & Schlecht.) Sparingly villous on the petioles, lower side of the 

 leaves, and calyx : stems very lax and slender, from a slender root- 

 stock, often rooting at the lower nodes : leaves subreniform-cordate, 

 abruptly short-acuminate : inflorescence very lax and open : sepals 

 thin-membranous, lanceolate, acute, 1 to 1^ lines long. — 944 Botteri ; 

 Sumichrast ; cult. Hort. Kew. 



Drtmaria glakdulosa, Bartl. (D. ramosissima, Schlecht.) 

 Glandular-pubescent throughout: stems ascending or decumbent, 

 from a stout rootstock : leaves triangular-ovate, acute or acuminate : 

 inflorescence very diffuse : sepals rather rigid, lanceolate, acuminate, 

 1-nerved, 2 lines long. — 51 Parry & Palmer; 1308 Berlandier ; 

 Palmer (Carmen Island). The original of the species is described 

 as an annual. 



Drtmaria suffruticosa, Gray, in herb. Suffrutescent at base, 

 much branched, nearly a foot high, smooth and glaucous : leaves 

 narrowly linear, 6 to 12 lines long: cymes few-flowered, terminal, 

 the flowers large and reflexed: sepals ovate or rounded, 2.V lines 

 long; petals included, fimbriately margined below, cleft above into 

 several linear lobes : capsule broadly ovate : seeds surrounded by a 

 conspicuous fimbriate crest. — At San Lorenzo de Laguna, Coa-
