LOCK : ECOLOGICAL NOTES 
Descriptive .—Specimens of the form previously known 
here as T. trioniflora were sent to Kew this year and there 
determined to belong to the variety T. elegans of Urban. 
A good figure of this variety appeared in Curtis’s Bot. Mag., 
vol. XXVI., No. 2,016, in which the long-styled form is 
accurately represented under the name Turnera trioniflora. 
The figure of T. angustifolia, vol. IV., No. 281, is also quite 
unmistakable. 
The plants of T. elegans which I have examined are 
markedly dimorphic. The flowers are perigynous, and in 
both long- and short-styled forms the petals are inserted 
on the tubular receptacle nearly 2 mm. above the level of the 
top of the ovary. The stamens are inserted between the 
petals, but lower down just on a level with the insertion of 
the styles upon the ovary. At this point, that is to say, the 
edges of the band-like lower part of the filament become fused 
with the receptacle ; but the central part remains free, and a 
space is thus left which forms the honey tube or nectary. The 
opening of the nectary is thus outside the base of a stamen 
and between the bases of two petals. Its mouth is protected 
by fine hairs situated on the bases of the adjoining petals. 
The three free styles terminate in much branched brush-like 
• stigmas. 
The presence of two styles only was noted as a rather 
frequent abnormality. This condition appeared to be always 
due to a fusing together of two of the three normally free 
styles ; and in this way the semblance of a small fasciation 
was produced. The anomalous flowers seemed to be as 
frequently of one form as of the other, and made up nearly 
1 per cent, of those which I was able to examine. 
The anthers of the long-styled form and the stigmas of 
the short-styled lie relatively close above the opening of the 
nectary. The longer styles or stigmas stand higher up, but 
spread out so as to leave only a narrow space between them¬ 
selves and the funnel-shaped corolla. All the anthers 
become completely extrorse by twisting during the later 
development of the bud.
