T. elegana differs markedly from T. angnstifolia in the 
following points :-(l) The plants are heterostyled, and, as 
will subsequently be seen, (2) self-Bterile ; (3) the habit 
is more branched and spreading in the former plant; (4) 
the branches are thinner and (5) more herbaceous ; (6) the 
leaves are oval and only half as long ; (7) the bracteoles are 
about 1 mm. wide, setaceous, and purple in colour; (8) the 
calyx tube and honey tube are only half as long as those of 
T angnstifolia; (9) the calyx is edged with purple ; (10) 
the corolla is of a pale cream colour, shading into yellow 
and with a dark purple spot at the base; (11) the petals 
are nearly twice as wide as those of T. angnstifolia and 
overlap when the corolla is fully expanded; (12) all the 
anthers are extrorse; (13) the fruits are more pointed at 
the apex, they are (14) more hairy, and (15) much smaller ; 
(16) the seeds number usually fewer than twelve, as against 
fifty or more in T. angnstifolia, and they are (17) nearly 
twice as large. 
In view of these differences, all of which appear practically 
constant, I would suggest the propriety of regarding this 
form as a distinct species from T. angnstifolia (ulmifolia), 
and in this case a return might be made to the name T. 
trionifiora, SimSj 1820. 
It is no doubt probable that Urban was induced to follow 
Linnseus in retaining T. elegans as a variety of T. ulmifolia 
by a study of intermediate “ varieties,” and indeed T. Cunei¬ 
forms seems to show a transition in at least one respect, 
namely, the position of the anthers. Not having had the 
opportunity of examining other forms, I can only point out 
here the striking differences which exist between these 
so-called varieties. 
In May and June of this year I began experiments in 
artificial pollination with T. elegans in the hope of being 
able to compare the offspring of legitimate and illegitimate 
pollination. Up to the present time, however, I have not 
succeeded in obtaining a single seed by the illegitimate 
method of fertilization. While engaged in this way my
