vated spathes of the inflorescence, besides the accordance 
of habit. ‘This may seem an unimportant feature, but marks 
like this are not to be slighted in the composition of generic 
groups; especially in a tribe of plants of such simple confi- 
guration as that of the Ensatew, where they are found to de- 
termine in the general habit of the species changes as real as 
are consequent upon the apparently more important ones in 
tribes where the plants are of greater complexity of configur- 
ation. The value of a mark is to be estimated on the one 
hand by the degree of general likeness consequent upon its 
presence throughout the species of a group, and on the 
other by the degree of general difference consequent on its 
absence in the species of the confining ones. In the Ensatw 
very strange and conspicuous disparities in the proportions 
and inflections of the corolla and floral organs, are frequently 
found to be followed by no difference in the general habit 
of the species greater in degree than that which must always 
exist even between the nearest members of a genus. While 
avery obscure and inconspicuous mark of some other kind 
is often found to determine peculiarities in the general habit 
of a greater or less portion of species; and which peculia- 
rities are also seen to disappear by phases that answer to 
and keep pace with others, through which the disappearance 
of this mark takes place at the confines of the group, 
- Grandiflora is native of the Cape of Good Hope, and | 
was cultivated at the Chelsea Garden by Miller, in 1758. 
The drawing was taken this spring in the same garden. 
Bulb-tuber about the size of a Filbert, with pale fibro- 
membranous integuments. Leaves 5-8, collaterally distich, 
‘ensiform, equitant, finely striated, shorter than the stem, 
generally bulbiferous in the axils. Flowers 1-5 or more, 
distantly spiked, upright, two inches in depth, parti- 
-coloured, sometimes almost entirely of deep violet. purple, 
at others white or yellow and variously marked with purple, 
without scent. Spathe whitish, subdiaphanous, equal to the 
tube. Corolla regular, funnelform, outspread, limb about 
4 times as long as the faux and tube taken together, stel- 
lately expanded, segments cuneately oblong. ~Stamens 
-twice shorter than the limb, inclining one way and diver- 
gent: anthers long, linear, cream-coloured. Stigmas spread- 
ing, white, half an inch long, linear, foldingly channelled 
and pubescent on the inner side. So
