APPENDIX. 439 



grass-like leaves, but the root, wliich has not boon collected, is described as an edible " bulb" instead of 

 thickly fibrous as in the rest of the tribe. The stem is 2° high, the yellow flowers 2' long, on short jointed 

 pedicels, the segments twice longer than the tube and 5-7-nerTOd; stamens 6, with equal filiform fila- 

 ments inserted in the throat; capsule subglobose, substipitate, many-seeded; leaves with a membranous 

 and strongly undulate margin. Found in New Mexico and Western Arizona. 



The tribe Odonfostemonew, characterized by a bulbous root, racemosely panicled flowers, and sparingly 

 leafy peduncle, is limited to the single Californian genus and species Odontostemum Hartwegi, Torr. Pac 

 S. E. Sun. 4. 150, t. 24. This is 1-2° high, with grass-like leaves, and white tubular flowers 5-6" long, 

 the at length reflexed segments equaling the tube ; pedicels strict, 3-6" long, in a loose 10-30-flowered 

 raceme ; stamens 6, on short filaments united at base and inserted in the throat, alternating with 6 linear 

 stammodia ; style elongated; capsule sessile, globose, 3-6-seeded, loculicidally 3-valved. 



The Millem are characterized as bulbous herbs, with naked peduncles, and umbellate or rarely solitary 

 flowers, and are divided into the following genera. 



* Corolla-tube furnished with a crown. 



1. ANDROSTEPHIUM, Torr. Tube funnelform, equaling the segments. Filaments united into a 

 crown at the throat of the tube. Capsule loculicidally 3-valved, many seeded.— A Texan genus of a single 

 species, A. violaceum, Torr., Bot. Mex. Bound. 218, having a tunicated bulb, an umbel of 3-4 flowers 

 upon a scape 2-4' high, the perianth 10-12" long. 



2. BESSERA, Sohult. Tube carapanulate, 4-6 times shorter than the segments. Filaments united to 

 the middle, filiform above. Capsule septicidally 3-valved, many-seeded.— A single Mexican genus and 

 species, B. elbgans, Sohult., having a tunicated bulb, a 4-10-flowered umbel on a fistulous scape 1-2" high, 

 and a deep-red perianth 9-10" long, with carinate segments. 



* * Without crown. 



3. LEUCOCOEYNE, Lindl. Perianth funnelform or subrotate, the segments equaling or shorter than 

 the tube. Anthers 3, sessile in the tube. Staminodia 3, spur-shaped, inserted at the throat.— Chili and 

 Peru. 



4. BEODMIA, Smith. Perianth funnelform, (in B. coecinea broadly tubular,) the segments longer or 

 shorter than the tube. Anthers 3, sessile, or nearly so, at the throat. Staminodia 3, petaloid, in one 

 row with the anthers. 



5. MILLA, Cav. Perianth funnelform, the tube cylindrio or campanulate, the segments equaling or 

 2-4 times longer than the tube. Stamens 6, perigynous, in 1 or 2 rows. 



BEODI^A. 



§ 1. EUBEODIJilA. Scapes erect ; perianth funnelform, the oblong-lanceolate segments equaling or 

 exceeding the tube ; anthers not winged. 



* Umbel loose, the pedicels elongated ; ovary shortly stipitate. 



1. B. GRANDirLORA, Sm. Bulb brown-coated; leaves 4-6, subterete, 1^" broad; scape 6-18' high; 

 valves of the spathe many, linear; umbel 2-8-fiowered, pedicels unequal, 3-18" long; perianth 9-15" long, 

 violet, the segments exceeding the tube, the throat 1^-2" broad; anthers 3" long, on 1" long filaments ; 

 staminodia subentire, equaling the anthers ; style 3-4" long ; cells 3-4 seeded. — From British Columbia 

 to California. Var. maokopoda, Torr., has a very short scape, the pedicels 3-6' long. Var. majok, Benth., 

 is taller and stouter, the perianth 18-21" long, with a broader throat and longer segments. 



* * Umbel dense, the pedicels short or almost wanting ; ovary sessile. 



2. B. CONGBSTA, Sm. Bulb brown-coated ; leaves 3-4, subterete, l|-2" broad ; scape 1-2° high ; 

 valves of the spathe 3-4, lanceolate ; umbel 6-12-flowered, the pedicels 1-3" long ; perianth 8-9" long, 

 deep violet-blue, the segments about equaling the tube ; anthers sessile, 2^" long, deeply notched at top ; 

 staminodia cuoullate, deeply emarginate ; style 2" long ; cells 5-6-seeded. — From British Columbia to 

 N. California. 



3. B. MtTLTiFLOKA, Benth. Scape 1-2° high ; flowers 6-20, blue, 6-10" long, exceeding the pedicels, 

 the segments about equaling the ventricose tube ; anthers 2" long ; staminodia lanceolate, entire. See 

 page 353. 



5 STEOPHOLIEION. Scape long and twining ; perianth funnelform, the oblong-lanceolate segments 

 about equaling the ventricose tube ; anthers winged. 



4. B. voLUBius, Baker. {StroplioUyion CaUformeiim,Toii., Pac. B. B. Sun. 4. 149, t. 23.) Leaves 3-4" 

 broad ; scapes 4-12° long ; valves of the spathe 4-5, lanceolate ; umbel 15-20-flowered, pedicels 3-9" long ; 

 perianth rose-purple, 5-6" long ; anthers sessUe, emarginate-winged, IV long ; staminodia ligulate,
