102. Iris Forrestii W. R. Dykes, l. c., p. 418, fig. 190. — Rhizoma 
gracile; folia linearia, subpedalia, !/, poll. lata, supra nitida, infra glauces- 
centia; caulis pedalis, foliosus, fistulosus; spathae 1—2 florae, valvis vi- 
ridibus, acutis, 2—3 poll. longis; pedicellus 1—1!/, poll. longus; ovarium 
trigonum; tubus latus, !/, poll. longus; segmenta omnia pallide lutea; 
exteriora depressa, oblongo-cuneata, ungue castaneo-venoso; interiora 
erecta oblongo-lanceolata, ungue canaliculato; styli rami saturatius lutei; 
cristis quadratis, sese tegentibus. — North-west Yunnan: In open 
mountain meadows on the eastern flank of.the Lichiang Range (Forrest). 
— Both these Irises have yellow flowers, and they are both closely related 
to I. sibirica and I. Clarkei. They are distinguished, however, by the 
following characteristics. In J. Wüsonü the flowers are borne on long 
pedicels, as in the western forms of I. sibirica; in 1. Forrestii the pedi- 
cels do not exceed an inch in length. In the former the styies are very 
narrow and the standards spreading, as in I. Clarkei, with the edges of 
the blade curiously crimped; while in the latter the styles are broader 
than the haft of the falls, and the standards almost erect with smooth 
blades. The foliage also of the two plants is quite distinct, that of 
I, Wilsonii resembling the growth of the Oriental forms I. sibirica, while 
leaves of I. Forrestii are narrow and grassy,. and, morewer, have the 
polished upper surface and glaucous under-surface, which are so marked 
features of I. Clarkei Moreover, I. Wilsonü grows to twice the height of 
I. Forresti. 
103. Iris Bulleyana W. R. Dykes, l. c., p. 418. — Rhizoma gracile, 
late repens; folia ensiformia supra nitida, infra glaucescentia; eaulis sub- 
pedalis, fistulosus; spathae biflorae, valvis viridibus acutis. — Yunnan, 
— I. Clarkei simillima sed caule fistuloso facile distinguenda, — A link 
between Iris sibirica and Iris Clarkei, for it has the hollow stem of 
I. sibirica, although in foliage and growth it is very similar to I. Clarkei,
