The Evansia Section 
for it is not quite so uniform as that of Loppio and yet the darker mottlings are not nearly so con- 
spicuous as those on the falls of /. teclorum. The foliage is not identical with that of either of the 
parents and the same is true of the ovary, tube and spathes, 
A still more obvious compromise between the characters of the two parents is to be found on the 
blade of the falls, where the crest splits up into fine hairs to form a scanty beard. (Cf. the enlarged 
drawing of a part on Plate XX1\.) . . .. . , 
More recently Herr F. Scheubel of Oberlahnstein has obtained similar results by crossing some 
early dwarf Pogoniris, probably some variety of I. chamaeiris, with pollen of /. tedorum. I have not yet 
seen living flowers of this cross, but from the dried fragments that were sent to me and from the 
description, it was easy to see that a similar compromise between the characters of the two parent 
SPeC1 U^fort U nrtely e<1 these hybrids, as well as others which have resulted from crossing widely separated 
soecies have so far proved to be completely sterile. In consequence, they have not thrown much light 
on the’ questions of the origin of the beards and crests in Irises as we know them to-day, and of 
their relationship to the beardless species. 
The species comprised in the section may be differentiated as follows: 
f Stem not produced or extremely short. 
\ Stem produced. 
( Stem unbranched. 
\ Stem branched. 
C Spathe consisting of a single valve. 
2 ' (Spathe consisting of two valves. 
( Leaves thick, smooth, with glossy upper- and glaucous under-surface. 
3 ' \ Leaves thin, distinctly ribbed, both surfaces slightly glaucous. 
fRhizome green, stem tall, much branched, flowers small. 
* ( Rhizome buff, stem shorter, less branched, flowers large.
