355 Commonwealth Avenue, Boston, I. .so. October 10th, 1523 
Bear Mr. Powell: 
The package with the Hexisea species came through 
all right, this morning. This package came by the Port of Boston. 
In future it will he wise to send by Boston boats. The Custom 
officials of Boston seem to have more education than those of Hew 
York. So much for that. 
333 Ujg&Um -QDJioaftifalia Reichb. f. This differs 
from £, ibldeiitata in the outline of the perianth segments and 
in the heavy callus on the base of the labellum. It is a mighty- 
rare species. I know it from the Mexican type. I am surprised to 
have it turn up in Panama. I should like to see more material 
of this species. Up to the present time it has been difficult to 
do much with the Hexisea species as they are not well represented 
in herbaria. Only about five species have been described. The 
one doubt regarding £[. hldentiifa is the fact that your material 
does not exhibit the bidentate character of the column wings on 
which Bindley founded the specific name, 
I turned up a new species of Pleurothallls to¬ 
day among Lahkeater , s specimens; an odd little thing with an elon¬ 
gated rhizpme and alternate orbicular leaves. I am publishing 
this in Sched. Orch. 6. 
Many thanks for the additional specimens of 
EBiflfiBdKum imdlc-qa sp. nov. There is no doubt but that this is 
a notable addition to the genus. I have it figured and described 
for Sched. Orch, 6 , 
Mr. Schweinfurth has a fresh supply of bottles 
for you. It is surely a profound pleasure to work on your species 
when the alcoholic material is at hand. A word of advice; When 
you send Stanhopeas Coryanthes and similar things, it will be 
well to put cotton in the bottles to keep the flowers from swash¬ 
ing about. Unless they are guarded in some way they break. It 
would also be well to use very weak alcohol and let us strengthen 
the solution here. But such bottles should be marked. Weak alco¬ 
hol prevents brittleness. 
305 may be new. I have been unable to run it 
down, but It may be a color variation . 
307. Haxill&ria sp. Only one flower with the 
specimen. This is closely allied to If, curtipes Hook, f. but the 
sepals appear to be narrower etc. This may be new. I would rather 
wait for additional material before describing it.It is also close 
to H. Powellii Schltr, but different. 
In a few days I will have more determinations 
for you. I intend to be very punctilious and at short intervals 
I will eend you bulletins to keep your spirits high. 
With the best of good wishes, 
Yours faithfully,
