 upon a figure in Hermann's Paradisus (Hermann, Para- 

 disus Batavus, t. 230, 1705), which represents a plant 



anth-tube : fr. 3-celIed, many-seeded. Native of the 

 mountain and table land region of Mes.— Five species 

 have been described, but recent explorations have 

 brought to light some 5 or 6 additional species. While

Alba, Boiss. Wild Mustard. Tall : Ivs. pinnatifld 

 and rough-hairy: pods spreading, hairy, the lower part 

 thick and few-seeded : seeds pale brown, large. Weed, 

 from Europe. 



Sinapistrum, Boiss. Charlock. Tall : Ivs. strong- 

 toothed, or sometimes nearly lyrate : pods knotty, 

 glabrous or hairy, the upper third indehiscent and 

 2-edged, usually 1-seeded. Weed, from Europe. 

 BB. Pod distinctly 4-angled.

 spreading and loose grower : Ivs. pinnatifld, somewhat 

 hairy : pods short and erect, glabrous ; seeds small and 

 dark brown, pungent, supplying the mustard of com- 

 merce. Cult, in Eu., but a weed in this country. -Com- 

 mercial mustard is the flour of the seeds of this species 

 chiefly, but the seeds of B. alba and probably of B. 

 juncea are sometimes used. L_ jj_ B_ 



BBAVOA ( Bravo, Mexican botanist). Amaryllid&cece . 

 A small genus, much resembling in some of its species 

 the tuberose (Folianthes), and considered by the writer 

 as hardly distinct from it. Stems slender, from small 

 thickened rootstocks: Ivs. mostly basal: inflorescence a 

 lax spike or raceme; fls. always in pairs more or less 

 bent or curved ; stamens 6, included within the peri- 



the flowers are not as showy as the common tuberose, 

 yet the genus should be found in every choice bulb col- 

 lection. Only one species has been cultivated to any 

 extent, and even this species is not well known. As the 

 in the high mountains of Mexico, 

 they ought to be hardy in the 

 southern stretches of the tem- 



geminiflora, Llav. & Lex. 

 Mexican Twin Flower. Stems 

 1-2 ft. high: bulbs small, 1-1}^ 

 in. long, the outer scales cut 

 into fine fibers at the top : basal 

 Ivs. linear, erect, 6 lines or less 

 broail, smooth : fls. in a slender 

 raceme, reddish or orange-col- 

 ored ; lobes minute, rounded. 

 B. M. iH\. — Handsome, and 

 worthy of more attention. 



B. Bulliana. Baker. Basal Ivs. 

 described as lanceolate, 1-lH in. 

 broad : fls. in 5 or 6 pairs, white. 

 Seemingly too near the little known 

 Polianthes Mexicana. Not in cult.— 

 B. sessilifldra, B. denaiflbra, and B. 

 singulifldra are rare species, only 

 known from herbarium specimens. 

 The latter two, however, should 

 probably be excluded from this 

 group. j_ N. Rose.
