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-lobed ; style filiform, 2-fid with 2 capitate stigmas, or entire with a 2-lobed 
stigma. — Nutlets 4, ovoid, rugose, trigonous ; scar basal, large flat.—Species 6 ; 
Himalaya, Siberia, the Caucasus. 
The character of the stigma, by which Bentham mainly separated Arnebia 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 fruit sometimes nearly 1 in. and sublanceolate. Corolla-tube as long as the sepals 
in flower or exceeding them by j;-iin.; lobes Àj in., varying in breadth. Flowers 
dimorphic, one form having 4 exserted anthers, and short 2-lobed stigmas, the puer 
With included anthers between the capitate stigma. (See Fisch. § Mey. l.e.) Nut ir 
nearly as in M. Benthami, but larger.—There is difficulty about the specific name 0 
this species; M. endochroma, H. f. 4 T. is a name published without a description, 
and it is not known whether it was an error for M. euchroma or whether it was inten- 
to imply a species closely allied to Lithospermum euchromum. M. cyanoc De 
Benth, (= Munbya cyanochroa, Boiss. Fl. Orient. iv. 212. Arnebia tingens, Ad ^ 
~Todr. x. 96), does not differ from M. perennis, but by being more coarsely hispid; 1t
