the throat of the corolla, with the stigma in the middle of the tube ; or anthers 

 in the middle of the corolla-tube with the stigma, at the mouth. Ovary deeply 

 •4-lohed ; style filiform, 2-fid with 2 capitate stigmas, or entire with a 2-lo'bed 

 stigma. Nvtlets 4, ovoid, rugose, trigonous ; scar basal, large flat. — Species 6 ; 

 Himalaya, Siberia, the Caucasus. 



The character of the stigma, by which Bentham mainly separated Amebia from 

 Macrotomia, is largely sexual ; there is, however, no difficulty in separating the In- 

 dian species, the Arnebias having yellow flowers, the Macrotomias purple.

 in flower or exceeding them by i-| in. ; lobes ^ in., varying in breadth. Flowers 

 dimorphic, one form having J exserted anthers, and short 2-lobed stigmas, the other 

 <with included anthers between the capitate stigma. (See F^ch. ^ Mey. I. c.) Nutlets 

 (nearly as in M. Benthami, but larger. — There ,is difficulty about the specific name of 

 this species ; M. endochroma, H.f. ^ T. is a, name published without a description, 

 and it is not known whether it was an error for M. euchroTiia or whether it was inten- 

 ded to imply a species closely allied to Lithospermum euohromum. M. cyanochroa, 

 Benth. (= Mnnbya cyanochroa, Boiss. PI. Orient, iv. 212. Arnebia tingens, A. DC. 

 Prodr. X. 96), does not differ from M. perennis, but by being more coarsely hispid ; it 

 is frequent in Cabul and Persia.
