The Didieri group of Tulips are allied to the Gesneriane 
in stature, in the size of the flower and in the glabrous 
leaves and peduncles, but they differ by having the three 
outer segments of the perianth subacute. There are four 
principal forms, Didiert, mauriana, planifoliaand Billietiana, 
which differ from one another principally in the colour of 
the flower. They flower a little earlier than the Gesneriane 
and are found wild in the neighbourhood of St. Jean de 
Maurienne in Upper Savoy, whence we received a supply 
of bulbs at Kew in 1889. These at first produced a fine 
yellow flower, but next year it was tinged with red. Our 
plate was drawn from a plant that flowered at Kew in the 
last week of May, 1891. We have received from Mr. H. J. 
Elwes a form with a black spot at the base of the perianth- 
segments and black instead of yellow filaments. 
Descr. Bulb ovoid, bearing many accessory bulbs; outer 
tunics brown, with only a few adpressed hairs inside. 
Leaves four, subglaucous, much undulated, not hairy on 
the surface nor ciliated on the edge, the lower one oblong- 
lanceolate, six or eight inches long, the others smaller. 
Pedunele long, glabrous, erect. Perianth campanulate, 
above two inches long; segments pure bright lemon-yellow,
