74 CROCION ACHLYDOPHYLLUM 
curious sp. deemed a garden hybrid produced by Q. coccinea and 
Q. pinnata, leaves variously cut few alike, some reniform -with 
shorter cuts, flowérs handsome, large purple, tube clavate, limb 
flat stellate pentagone, stamens exserted. Seen alive in gardens, 
where sometimes spontaneous.”’ 
The Quamoclita pinnata Raf. above is certainly Ipomoea 
Quamoclhit Linn,. Sp. Pl, 159 (1753), the only pinnate leaved 
Quamoclit known by him at the time, and it is moreover the oldest 
binary application of the plant under the genus Quamoclit ante- 
dating Choisy’s name Quamoclit vulgaris' nine years, unless of 
course one admits the stupid duplicate binaries like Quamoclit 
OQuamoclit.

CROCION ACHLYDOPHYLLUM (GREENE.) 
An Ecological and Anatomical Study. 
BY R. M. KACZMAREK. 
In “Studies in Viola I”’ in the AMERICAN MIDLAND NATURALIST 
in the February issue of 1914 we intimated that the presence or 
absence of cleistogamous flowers in plants in the genus Viola, as 
hitherto held by most botanists, is becoming a recognized character 
for classification. It was undertaken to segregate the plants of 
this group taking into consideration their habit and the number 
of stamens in the so-called ‘“‘apetalous flowers’’ when present. 
On account of these important characters of distinction we pro- 
posed the segregates on the basis of this difference. 
We proposed the genus Crocion Nieuwland and Kaczmarek? 
for the stemmed yellow violets of which V. pubescens (Ait.)§ is 
the type. In our opinion the western plant confused by botanists 
under the name of V. ertocarpa (Schwein.)4 is really V. achlydo- 
‘Whether the Jpomoela Cardinalis (Cardinal Creeper) offered by A. 
Boddington, of New York, is the same as Quamodit Slotert, I have been un- 
able to find.
