[9 Oct. 1867] Ihre Beobachtungen über Orchideen sind ausgezeichnet, besonders die Bestätigung in Bezug auf Cypripedium, und dies sollte sicherlich eines Tages veröffenlicht werden. Es ist fast ein so schönes Beispiel wie das von Coryanthes mit ihrer mit Wasser gefüllten Lippe, wie es Crüger beschrieben hat Sie sprechen von dem Geruch des Cypripedium, aber bei einigen ausländischen Arten sah ich kleine Flüssigkeitströpfchen an den Haaren innerhalb der Lippe, welche ein wahrscheinlicheres

effected in these cases is not yet known. That insects are the agents there can be no doubt; for Dr. Crüger saw a bee (Euglossa) with a pollinium of a Stanhopea attached to its back; and bees of the same genus continually visit Gongora. Fritz Müller1 has observed, in the case of Cirrhæa (Bot. Zeitung, Sept. 1868, p. 630), that if one end of the pollen-mass be inserted into the narrow entrance of the stigmatic chamber, this part, from being bathed by the stigmatic fluid, swells, and the whole

lateral entrances; within this chamber there are curious fleshy ridges. The most ingenious man, if he had not witnessed what takes place, could never have imagined what purpose all these parts serve. But Dr. Crüger saw crowds of large humble-bees visiting the gigantic flowers of this orchid, not in order to suck nectar, but to gnaw off the ridges within the chamber above the bucket; in doing this they frequently pushed each other into the bucket, and their wings being thus wetted they could

essentially the same manner, but entailing changes in every part of the flower. The nectar may be stored in variously shaped receptacles, with the stamens and pistils modified in many ways, sometimes forming trap-like contrivances, and sometimes capable of neatly adapted movements through irritability or elasticity. From such structures we may advance till we come to such a case of extraordinary adaptation as that lately described by Dr. Crüger in the Coryanthes. This orchid has part of its labellum or

Von solchen Bildungen kommen wir dann zu einer solchen Höhe vollendeter Anpassung, wie Crüger neuerdings bei Coryanthes beschrieben hat. Bei dieser Orchidee ist das Labellum oder die Unterlippe zu einem großen eimerartigen Gefäße ausgehöhlt, in welches fortwährend aus zwei über ihm stehenden absondernden Hörnern

The long-projection on Labellum surprisingly thick sweet pleasant taste - the so-called nectary has not thin walls no doubt answers to cavity; the difference is that it lies close to column. It is impossible to understand how disc, with upturned end rests. In this species the hinge is elastic the pollinia springy, to one side rests on little upturned end of disc - no doubt this hinge elasticity replaces hygrometric movement we know
