212 MR. R. A. ROLFE ON THE APOSTASIER. 
a certain analogy in the staminal arrangement, and perhaps in 
the economy of fertilization, to Cypripedium. Both the species 
are admirably illustrated. 
In 1833 * Lindley raised Apostasiez to the rank of a distinct 
natural order, another group of Orchidex being also so separated 
under the name Panillacee. This latter group was abandoned 
in a later work f, though Apostasiee was retained, on account of 
the three-celled ovary and the style being free for the greater 
part of its length. Here Lindley remarks, “the Order seems as 
if connecting Orchids with Hypoxids.” 
Between 1830 and 1838 Bauer's * Illustrations of Orchidaceous 
Plants’ appeared, in which Apostasia is admirably figured 1, with 
the single exception of the pollen. That of Apostasia nuda is 
here represented as cohering in tetrads, a point in which no sub- 
sequent author agrees, and which is quite at variance with my 
own observations. 
Attention was called to this very point by Griffith $ in describing 
Apostasia Brunonis, in the following note :—“ With respect to the 
pollen, in this species at least, it has no affinity with that of Or- 
chidee ; Mr. Bauer, however, has figured that of A. nuda, which 
has a manifest and close resemblance to that of Orchidee.” He 
then describes the pollen from his own observations as “ pul- 
vereous " and differing *only from the common form of pollen 
in having but one tegument. It appears to be lanceolate-ovate, 
with one or three elevated lines of a whiter colour than the 
remaining part. Immersed in water, the lines generally disappear, 
and it appears like an oval or roundish vesicle, very transparent, 
containing very minute granules and a viscid fluid. "There is no 
ternary or quaternary cohesion." But on examining Griffith's 
specimens l find them to be identical with A. nuda, R. Br., so 
that the error must be simply one of observation, and perhaps 
arose from Bauer not clearly seeing all the details and trying to 
make the pollen fit with that of other Orchideous genera. 
In 1834 a second genus of Apostasiee was described by Blume ||, 
under the name Neuwiedia, differing from Apostasia in its sub-
