THE ORCHID REVIEW. 173 
the suffusion of the purplish rose which occurs in so many forms of the 
latter. The small and numerous, sometimes line-like spots of O. gloriosum 
are seen in combination with the yellow ground, as in O. x hebraicum, 
with the white ground, as in O. x Jenningsianum, or with the suffused rose 
ground, as in some forms of O. x Ruckerianum. Or in each case they may 
be few and larger, and ranging from chestnut to deep red-brown ; or, occa- 
sionally, they may be almost or quite absent, as in unspotted forms of O. 
crispum. The branched inflorescence ‘of O. gloriosum also appears in O. 
hebraicum. With regard to shape, some forms have broad segments, 
approaching those of O. crispum, and others very narrow, asin O. gloriosum ; 
or the increased size of O. crispum may be devoted entirely to lengthening 
the segments, as in O. x Brassia, a form with very long, narrow segments, 
not matched among varieties of either parent. This form, originally almost 
unspotted, has now appeared with the dense spotting of O. x hebraicum, 
and the others are all connected by various intermediates, so that it is 
almost impossible to say where Andersonianum passes into Jenningsianum 
on the one hand, and into Ruckerianum on ‘the other, and this again into 
baphicanthum, which in its turn grades into Leeanum and deltoglossum, 
while the shape of lip of the latter co-exists with quite different colours. 
Jenningsianum again passes into hebraicum, and hebraicum into Brassia 
and deltoglossum, and so the cycle is completed in various directions, in the 
innumerable forms now in gardens. 
From the very nature of the case this must be so, when a series of 
hybrids are derived from the same two species, and in the present instance 
it seems to me that the best course would be to consider them all as 
Varieties of O. x Andersonianum. ‘They are not distinct hybrids, nor can 
they properly be placed as varieties of either parent, and the course pro- 
posed is the only alternative. Reichenbach proposed to make them varieties 
of one, under the name of O. x lanceans, but there is no need to coin a new 
Name for the purpose, when the old one answers so much better. 
Our knowledge of these forms has only been acquired by slow degrees, 
and two or three other species have been mentioned as probable parents. 
0. prestans has already been disposed of; O. leucopterum, mentioned by 
Reichenbach under O. x deltoglossum, has no better claim; while O. 
Odoratum, whose aid has been invoked to account for the yellow forms, 
does not grow with O. crispum at all. 0. gloriosum has been considered 
a$ Synonymous with it, but the two are not identical, though nearly allied. 
0. odoratum grows in Venezuela, where no gloriosum occurs, but is not 
found in New Granada, where it is replaced by O. gloriosum. In any case 
0. odoratum proper is not concerned in the parentage of the present hybrid. 
So far as I can ascertain the following is a complete list of the forms 
derived from QO. crispum and O. gloriosum, with references to original 
: descriptions and published figures :-—
