Maorotomia."] c. BORAGINEJB. (C. B. Clarke.) 177 



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.

ALPINE WESTERN HIMALAYA and WESTERN TIBET, alt. 10-14,000 ft., from the 

 Karakorum and Kashmir to Kumaon, frequent ; Royle, Thomson, &c. DISTRIB. 

 Cabul, Kashgar, Yarkand, Alatau Mts. 



Root perennial; stems 8-20 in. Radical leaves 5 by g- in., striated ; cauline 1-2 

 in., sessile. . Cymes 3-4 in. diam., many-flowered, pedicels 0-^ in. in M. endochroma, 

 H. f. & T. ; or condensed capitate few-flowered in Koyle's examples on which Litho- 

 .spermum euchromon, Koyle, was founded. Sepals ^-^ in. in flower, patently hirsute, 

 in fruit sometimes nearly 1 in. and sublanceolate. Corolla-tube as long as the sepals 

 in flower or exceeding them by ~~ in. ; lobes in., varying in breadth. Flowers 

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

 with included anthers between the capitate stigma. (See Fisch. fy 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. Sf 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- 

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

 Benth. (= Munbya cyanochroa, Boiss. Fl. 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.

Hispid herbs or undershrubs. Leaves alternate. Racemes simple or cymose, 

 one-sided, bracteate. Floivers yellow or purple, sessile or shortly pedicelled. 

 Calyx 5-partite or 5-fid ; segments acute, in fruit sometimes enlarged. Corolla 

 tubular or ventricose, throat dilated or contracted ; lobes 5, very short. Stamens 

 5, filaments attached near the middle of the corolla-tube linear short or long 

 or greatly dilated at the base ; anthers lanceolate, acuminate, free, conically
