324 civ. OROBANOHACE^. (J. D. Hooker.) [Cistanche. 



campanulate ; lobes 5, subequal, obtuse. Corolla-tube long, incurved, 

 dilated above ; limb spreading, oblique, lobes 5 broad, subequal. Stamens 

 4, subexserted ; anthers subtrans verse, often villous, cells equal parallel, 

 bases obtuse. Ovary 1-celled ; placentas 4, equidistant or in pairs ; stigma 

 broad. Capsule ovoid, laterally compressed, 2-valved to the base. Seeds 

 numerous, subglobose, reticulately punctate. Species 12, of the Mediterra- 

 nean region and N. central and subtropical Asia. 



C. tubulosa, Wight Ic. t. 1420, bis (C. lutea in letterpress) ; glab- 

 rous or pubescent, very stout, scales lanceolate, spike deDse-fld., calyx- 

 lobes obtuse, corolla-tube 2-3 times as long as the calyx, filaments hirsute 

 below, anthers woolly not apiculate. C. lutea, Wight III. t. 158 b, f. 4.

PUNJAB and SCINDE. DISTEIB. Central Asia and westwards to Arabia. 



Stem 1-5 ft., often as thick as the wrist, unbranched. Scales |- 1 in. Spike 

 6-10 in., sometimes 3 in. diam.; bracts lanceolate, longer than the calyx, bracteoles 

 narrower and shorter, linear. Calyx ^-f in. long. Corolla 1-lf in., yellow, much 

 incurved, base slender, tube inflated ; mouth f-1^ in. diam. ; lobes short. Anthers 

 subexserted, tip rounded or obscurely apiculate. Placentas 4, subequidistant. I 

 doubt this being specifically different from the common C. lutea, which extends to 

 Spain and Morocco, for I find an obscure mucro on some of the anthers. 



VAE. tomentosa ; stem above bracts and calyx sparsely woolly. Lahore, Thomson.
