48 THE ORCHID REVIEW. 
particularly with regard to hybrids from L. furfuracea and L. grandiflora, 
but I believe they are warranted by the facts. The absence of hybrids from 
both L. anceps and L. autumnalis with L. furfuracea and L. grandiflora is 
perhaps accounted for by different altitudes at which they occur.

MASDEVALLIA ORTGIESIANA. 
The Royal Botanic Gardens, Glasnevin, have long been famous for a2 
collection of Masdevallias, which is one of the most complete in existence, 
Mr. F. W. Moore, the curator, having for many years lost no opportunity of 
extending it. Consequently it contains many rarities which are only to be 
found in a very few other collections where these charming little plants find 
special favour. The above species is one of these rarities which is now 
flowering there. It belongs to the section Coriacez, and is the next ally to 
M. striatella, Rchb. f., though the tube of the sepals is shorter and broader. 
The leaves are linear-oblong and about four inches long, the slender single- 
flowered scapes being considerably shorter. The flowers are five lines long, 
and pale greenish white with three faint purple nerves on each sepal. 
There are no distinct tails, but the sepals are gradually narrowed to the 
apex. There are also three light purple nerves on the lip, which is papillose 
in front. It is a very interesting little plant.

ODONTOGLOSSUM x ANDERSONIANUM PULVEREUM. 
The wide range of variation in colour and marking of Odontoglossum x 
Andersonianum has already been considered in detail in these pages (vol. i. 
p- 170), and the difficulty of distinguishing its different forms, owing to the 
way they grade into each other, pointed out. It is becoming increasingly 
evident that the only practical way of dealing with these glorioso-crispum 
forms is to treat them as varieties of the original O. x Andersonianum, for 
the lines of demarcation between them are being gradually filled up by 
the appearance of intermediate forms. A brilliantly coloured and handsome 
form has appeared in the collection of De Barri Crawshay, Esq., Rosefield, 
Sevenoaks, which comes nearest to the variety Leeanum (O. x Leeanum, 
Rehb. f.). It has flowers of a very bright clear yellow, with very numerous 
small cinnamon-brown spots on the lower half of the sepals and petals, and 
a few similar ones on the lip, with a small blotch in front of the crest. 
Leeanum, as seen in the published figure (Orchid Album, iii., t. Ior), has 
deeper coloured flowers, with the sepals and petals somewhat suffused with 
orange-buff towards the margins, and the spots extending almost to the tips, 
while the blotch on the lip is larger.
