118 MISSOURI BOTANICAL GARDEN BULLETIN 
shine is permitted for the benefit of sun-loving terrestrial 
orchids. Of interest here was a large bed of the dove orchid, 
Peristeria elata, producing upwards of fifty flower spikes, 
averaging four feet high and well filled with maturing buds. 
The soil consisted of a heavy sandy loam, and Mr. Powell 
informed me that the plants grow under like conditions in the 
wild state, except that in the wild state they grow in associa- 
tion with grasses. Sobralias were also planted in similar beds, 
two noteworthy specimens being the new species, 8. Rolfeana 
and S. Powellii, in full bloom. Other terrestrial orchids 
growing in shade were various species of Habenaria, inc'ud- 
ing several undetermined species. Associated with these 
shade-loving terrestrials were some recently collected plants 
of the Mandarin orchid, Phragmopcdilum caudatum var. 
Warscewiczii. 
‘‘The greater part of the collection is represented by epi- 
phytes, the genus Epidendrum dominating all others by its 
many species. The beautiful Epidendrum atropurpureum 
var. rhodoglossum and E. prismatocarpum were in full bloom, 
as was also the new species of the bucket orchid Coryanthcs 
Powellti and C. Hunteriana. Mr. Powell remarked that it is 
almost impossible to get the natives to climb the trees to col- 
lect bucket orchids, as the large masses of roots are invariably 
infested with numbers of stinging ants. Removing a clump 
of these plants may be comnared with disturbing a hornets’ 
nest, but, according to Mr. Powell, who had exnerienced both 
adventures, the hornets are easier to combat than the thou- 
sands of small stinging ants. 
‘‘Some of the more showy orchids were T'richopilia suavis 
and 7. marginata growing upon large blocks of wood. Of 
recent discovery was the albino form of both species, 7’. mar- 
ginata var. alba being the most striking. The oncidiums in 
flower included the showy O. ampliatum, several plants of 
which were also observed in the central parkway in Panama 
City, attached to trees. There were also several long spikes 
of O. panamcnse which somewhat resemble O. altissimum. 
Various species of Pleurothallis, Stelis, Scaphyglottis, and 
Masdevallia were in blocm, the rare white-flowered M. Living- 
stoneana being particularly noticeable. 
“On account of the atmospheric conditions the growing of 
orchids in Panama is considerably simplified. During the
