Ir ever I had great doubts about the affinity of plants it has occurred in the case of Zygopetalum Mackaii and Z. inter- 
medium. I never believed in the characteristic value of the hairiness on the surface of certain parts of the labellum. 
After seeing flowers again and again, I determined finally to watch the shape of the lip itself. I had been prevented 
from doing so by our magnus Apollo, Dr. Lindley himself. This excellent observer had then just combined the cuneate 
lipped form of Sir William (then Professor) Hooker (see Bot. Mag., tab. 2748, and Lodd. Bot. Cab., 1614), with the other 
form having an abruptly dilatate lip (Bot. Reg., 1433). Now, indeed, the Lindleyan dilatate lipped form has the lines on 
the labellum usually velvety, while the Hookerian type with the cuneate lip, smaller flowers, and flat sepals and petals, 
has the veins usually naked, though there are exceptions. 
Zygopetalum intermedium has a tendency, now and then, to get an undulation on its petals and sepals, which has 
been carefully represented by Mr. Moon in the present plate. This species is decidedly far superior to Z. Mackaii, Hook. 
For years Z. intermedium alone was to be found in gardens, but of recent years the Hookerian plant has appeared here 
and there. The merits of Z. intermedium have also been acknowledged by Dr. Lindley, who distinctly remarked that “ It 
is perhaps the finest of the genus,” HI. G. Rehb. f. 
In the depth of winter, when even Orchid flowers are not plentiful, then are the merits of this favourite old Orchid 
most appreciated, its flowers being so beautiful and so fragrant, and borne in such an elegant way on tall spikes, 
which last for as long as eight weeks in perfection. It is one of the few Orchids that have found their way into 
general cultivation, for it is often seen finely grown in gardens where other Orchids are almost unknown. It is a native 
of Brazil, where it occurs in several provinces, but chiefly in St. Catharina and on the Organ Mountains. There it is 
often found growing on exposed rocks, away from the shade of trees, hence we may infer that it is a sun lover, although 
it is also found growing in partial shade on trees. 
Z. intermedium, like Z. Mackaii, isa very free growing plant and extremely easy to cultivate to perfection. We have 
seen specimens bearing from fifteen to twenty spikes, with from five to seven or even eight flowers on a spike—a beautiful 
sight in midwinter. It requires to be grown in a heavier compost than the generality of Orchids, as it is as much a 
terrestrial plant as an epiphyte. It may be grown admirably in turfy loam, provided the pot is well drained. Being 
a strong rooting plant it requires to be potted annually, the best time for this being as soon as the flowering season is past. 
It commences to form new growths simultaneously with the flower spikes, usually in December and January. It is then 
that it requires an abundance of water and a temperature ranging from 60 deg. to 65 deg. F., and a moist atmosphere. 
It continues to develop its new pseudo-bulbs throughout the summer, and when thes 
> are fully grown the plant should 
be rested by placing in a cool airy house and keeping it drier. The resting period is comparatively short, and the bulbs 
require longer time to mature in this country than in Brazil, where the resting season extends over a few months.
