rom the preceding quotations it appears that the term “ scor- 
pioid”’ has been used in two soa senses by continental authors, 
by DeCandolle and by Le Maout and Decaisne it is applied in- 
differently to all a ay by all the other authors it is 
applied to a particular form of unilateral cyme. 
We will now proceed to enquire as to the sense in which this 
term has been used in England. In the English edition of the 
‘ Traité Générale’ the words of Le Maout and Decaisne are literally 
reproduced, and t saci “‘scorpioid”” is evidently used in the 
Saat sense ae to it by the French authors. In Prof. Bentley's 
nual of Bot y? (Brd edition, 1873), on page 200, the words 
* helicoi a” and a» aeare oid are used synonymously, and a dia agram 
of a unilateral cyme is given which exactly resembles that given 
above, No. 1. These terms are applied indifferently to all uni- 
lateral cymes. In Prof. Balfour's ‘Manual’ (5th edition, 1875),

a scorpion’s tail—hence its name. . 278 (fig. 273 is a

sketch of this arrangement. The false axis ormed by

false axis, but in this case the bracts, which should a appear on the 
moat side, are not developed, and hence the cyme is not 
mplete. 
“In the helicoid cyme there is also a false axis formed by the 
basal portion " the separate axes, but the flowers are not placed in

this case the axes are arranged, not in two rows along 
one side of a false axis, but are elope at regular serve, so as to 
form an elongated spiral roun 
Masters, in the last edi tion of Henfrey’s ‘ a oenen 
Course,’ page 83, describes these inflorescences as follows, a figure 
of the ca ea cyme being given which is similar to o 
‘“« The subsidiary flower-stalks are sometimes developed all on the 
same side, when the inflorescence a curled from the greater 
growth on one side than on the other. Such cymes are called 
scorpioid cymes. At other times the subsidiary pedicels or flower-
