virides, subventricosae; pedicellus nullus; ovarium rotundato-trigonum; 
tubus 1—2 poll. longus, purpureo striatus; segmenta omnia nigro-purpurea, 
exteriora obovato-cuneata, barba ex albido coerulescente, interiora paulo 
pallidiora, obovato-unguieulata. — While going through the Portuguese 
specimens of this /ris in the Kew Herbarium I found one plant that 
differed from I. subbiflora in several ways, and which was collected on 
Monsanto, The chief difference lies’ in the fact that, whereas in sub- 
biflora the stem bears several small bract-like leaves, and has small 
purple-stained spathes, the Monsanto plant has a naked stem, and remar- 
kably long and broad, green spathe valves.

similem, haud tamen ita gravem exhalantes, — From Baron Max von 
Fürstenberg, Hugenpoet near Essen. — This plant is allied to Z. Mur- 
rayanum (Gardn.), a half-forgotten species, described and figured 71 years 
ago in the Bot. Mag. (t. 3674), and mentioned by Mr. Rolfe in this 
journal (1888 II), and in the Flora Braziliana, Il, 575. Our plant is 
smaller in every part, and without any trace of red on the lip and 
column, but, except for these differences, it is certainly a very similar 
plant, so that now we have a little group of two species. "Therefore, I 
cannot but declare Z. Binotii (de Wildem.) synonymous with Z. Murray- 
anwm (Gardner) The descriptions, for instance, in Flora Brazil, IL, 575, 
and Ill, 575, practically identical, and there are no discrepancies of any 
systematie value, neither in form nor in dimensions between the old and 
the new species, De Wildeman considered his plant to be a hybrid 
between Zygopetalum and Colax, or perhaps other plants. I regret that 
I must decline to follow this gentlemen in this direction. On account of 
its hairiness inside, I regard my new species as a hybrid between a 
Zygopetalum and a Lycaste, and, because of its peculiar perfume, I con- 
sider it to be derived also from a Stanhopea. Z. Binotii is said to be 
found near Theresopilis, in the province of Rio de Janeiro, but it is not 
very probable that a botanist like the late Glazion, who knew every 
spot of this province, and who was a very experienced connoisseur of
