three hundred years. The use of the name has been extended to cover the 
form with spotted leaves, and it has recently been sought to limit it to this 
form, but this, according to the latest evidence, is a hybrid with O. maculata. 
A recent account of the distribution of the so-called O. pratermissa 
suggests that the green-leaved form is a constant and distinct species, which 
is in complete accord with many of the earlier records of the widely-diffused 
O. latifolia. 
The Madeiran O. foliosa affords a quite parallel example, for it has 
unspotted leaves, hence the surprise felt by Mr. Wolley Dod when he found 
plants with spotted leaves in his garden. Examination, however, showed 
that the latter were spontaneous hybrids with O. maculata, which was 
growing near by. The same hybrid has since appeared with Sir A. Buchan 
Hepburn under similar circumstances, and the hybrid is now known as O. 
Hepburnii (see p. 151). This affords a parallel case to that of O. Braunil 
(see pp. 164, 177), and the question remains whether all the so-called O. 
latifolia with spotted leaves are not forms of O. Braunii or its derivatives, 
for the two parents often grow together, and the resulting hybrids are com- 
pletely fertile. |

It is true that there are forms of O. maculata with unspotted leaves, 
but in such cases the flowers are white or nearly so, and it is simply a case 
of albinism, for in O. maculata the leaves are copiously spotted with brown as 
anormal character, not unspotted as in O. latifolia proper, and in O. foliosa. 
Further observations where O. latifolia grows by itself should help to 
elucidate a very interesting problem. And several others await solution 
where allied species grow together and yield natural hybrids. 
eRs.—A remarkable flower of Cattleya 
Iris (bicolor % Dowiana), is sent from the collection of Sir Jeremiah 
Colman, Bart., Gatton Park, in which the lip may be described as half 
petal, half lip, while the column has an additional perfect anther, containing 
four pollinia. It illustrates once more t ct that the Orchid 
lip consists of the two lateral stamens © ' 
confluent with the median petal, and modified into petaloid staminodes. 
these staminodes happen to revert, by wandering from their usual course 
and joining the column, the result is that three anthers are developed, each 
containing the usual number of pollinia, as in the case of a flower of 
Cattleya labiata previously recorded (0. R., ii, P- 358). sess the present case 
Only one stamen has reverted, namely Az of the Darwinian notation, the 
result being as follows. One side of the lip (A3) has developed in the usual 
Way, the fleshy substance, purple colour, and the sinall auriculate side lobe
