192 THE WOODLANDS ORCHIDS 



boldly ribbed. The petals, dark at base, change to green, and 

 towards the tips have an edging of profuse crimson specks. 

 The slipper, very wide at the mouth, is greenish. 



Dauthierii albino. — A wonderful sport. Up the grass- 

 green dorsal, edged with white above, run strong lines of 

 darker tone. The petals, very narrow at base, are yellowish 

 green, suffused and lined with copper above, paler below. 

 The slipper shows similar colouring. 



On the same plant, open at the same time, but from 

 another stem, was a flower of the common Dauthierii type. 

 Still more remarkable, one year this second stem bore a 

 flower of which half the dorsal was pale yellow, the other 

 half coppery green, as is usual, thus betraying a futile in- 

 clination to rival its albino sister. The petals were scarcely 

 affected, however. 



Dauthierii marmoratum. — Another abnormal form. The 

 point of the dorsal, and the high shoulders, are white, the 

 rest crimson-maroon. From the point descend three or four 

 broad lines, or long splashes, of green, with striking effect. 

 The petals are marbled longitudinally with purple on a dusky 

 ground. The lip is dull, dusky crimson. 



hord Derby (Rothschildianum x superbiens). — An im- 

 mense flower — the grand dorsal rosy white, tinged with pale 

 green in the middle, pale purple on either hand, dark lines 

 circling upward over all. The petals, outlined with purple at 

 the base, change to pale green, almost to white, below and at 

 the tips. Great spots of darkest crimson stud the whole. 

 Slipper maroon, greenish at the toe. 



Evenor (Argus x bellatulum). — Ground-colour through- 

 out ochreous yellow. The dorsal has a purplish base and 

 maroon lines of dots. Broad round petals, closely spotted 

 with maroon. Slipper purplish above, ochre below. 



Excelsior (Rothschildianum x Harrisianum). — Dorsal 

 long, high-shouldered, greenish, with darkest crimson edging
