with a flat, often yery broad lamina to the labellum, and the 

 pollen-masses affixed to the surface of distinct flat stipites, the 

 scale-like glands also quite distinct. This would include A. ses- 

 quipedale and A. gladiifolium of Thouars, and A. funale, Bot. Mag. 

 2. Listrostachys, Reichb., in which the lamina of the labellum is 

 usually continuous with the spur, more or less concave at the 

 base, and tapering into a point, the pollen-masses attached to 

 distinct flat stipites, the glands or scales of the pollinarium also 

 distinct or more or less united. 3. Angrcecum proper, with the 

 flat lamina to the labellum of Macroura ; but the stipes of the 

 pollinarium often narrow, though flat, single and entire, but 

 often readily divisible into two, and sometimes perhaps naturally 

 bifid. The species appear to be numerous, and to a certain 

 degree polymorphous ; in several, however, the pollinarium is 

 imperfectly known. Eeichenbach has proposed a genus Aerangis 

 for an Angola species with an exceedingly long spur, in all 

 respects a true Angrcecum of this section, except that the stipes 

 of the pollinarium is divided to about the middle. A. caudatum, 

 Lindl.,has an exceedingly long spur and the column exceptionally 

 long. A. infundibular -e, Lindl., is remarkable for the long 

 funnel-shaped spur ; A. armeniacum, Lindl., for its unusually 

 small flowers ; and to the African and Mascarene species must 

 be added, notwithstanding its widely distant geographical posi- 

 tion, the (Eceoclades falcata, Lindl., from China and Japan, well 

 figured by Thunberg as a Limodorurn, as well as in Bot. Reg. 

 t. 283 and Bot. Mag. t. 2097, but with all the characters of an 

 Angrcecum of the typical section. Miquel unfortunately referred 

 it to Aerides, which led Franchet and Savatier to confound it 

 with the Aerides japonica, Lindl., a true Aerides, which has not 

 the slightest similarity with Angrcecum falcatum in habit or 

 character. Cryptopus, Lindl. (Beclardia, A. Rich., in part), is a 

 single Mascarene species, with remarkable lobed petals and a 

 peculiar pollinarium. JEonia, Lindl., has four or five Mascarene 

 species, with the pollinarium of Mystacidium and a peculiarly 

 shaped perianth, which induced Thouars to describe them under 

 Epidendrum. Mystacidium, Lindl., comprises about twenty 

 species, with the flowers usually much smaller than in Angrcecum, 

 and the pollen-masses affixed to distinct filiform stipites, either 

 exceedingly short or long, and often clavate or cup- shaped under 

 the masses. There is, however, here, as in Angrcecum, a con- 

 siderable variety in habit as in the structure of the flowers.
