336 THE ORCHID REVIEW. [NovEMBER, 1908, 
Parana, and about 1,000 miles from its mouth, the falls being in every way 
jarger than Niagara, and incomparably more beautiful. I left early in the 
morning the little wooden house, twelve miles from the Falls, where I had 
spent the night. It was in the month of May; the cold wet mist was still 
_very thick (very much as it has been here this Ist of October, only colder), 
everything being dripping wet in the forest, and it was not till between seven 
and eight that the sun had cleared it away, and then at mid-day it was as 
hot as our early summer. As we went along I enquired from our guide, 
through a friend, who was a good Spanish scholar, if there were any Orchids 
in the forest, and he said there were, and of one, the “ Casaca Romana” 
(Roman coat), he could show me where a plant grew, so on my way back 
we halted, and there was the plant I now have growing on a dead tree. It 
did not take long to gather it, and, as I have told you, it flowered this year. 
Had I known it to be of any interest, 1 would have taken more especial 
notice when it was in flower. One thing that struck me was the way the 
pollen mass was shot forward when the lip was touched; but I must say, 
from my remembrance of the flower, I should not have thought the 
description in your article answered to mine. Doubtless this plant is 
distributed in the dense forests of Brazil, Argentina (State of Missunes), and 
Paraguay, north of Lat. 26°. My plant came from 254N., 544 W.

INHERITANCE OF ALBINISM IN ORCHII S. 
Two more interesting cases of reversion arising from the crossing of albinos 
can be added to those already recorded (pp. 228, 265). 
Two coloured flowers of Cattleya labiata have been sent from the 
collection of R. G. Thwaites, Esq., of Streatham, and Mr. Black remarks 
that they are from a batch obtained by intercrossing two varieties having 
white sepals and petals, namely, C. 1. Amesiana and R. I. Measures’ vat. 
He adds: ‘‘ We have now flowered a considerable number, and have a good 
many in bud, and all seem to be coloured. We showed two of them at the 
R.H.S. meeting yesterday.” 
The other case is that of Cypripedium insigne Dorothy x C. i. Sandere 
mentioned on page 334. Mr. Appleton raised a cross between these two 
yellow varieties, and all reverted to quite ordinary forms, having green 
ground colour, with more or less spotting on the dorsal sepal. All that we 
saw had rather small spots, and in several cases less numerous than usual. 
Both the crosses mentioned were made in the hope of obtaining albino 
varieties, and we know that many others have been made with the same 
object. The result illustrates the benefits of cross-fertilisation in much too 
graphic a fashion, and raisers will probably be driven to try self-fertilisation 
more requently in the future. R. A. R
