We learn from the lady who brought this to England, that 

 the seeds are employed in Mexico as a source of arrow-root. 

 The plant must therefore be extremely common in some parts 

 of that country ; and we believe it has actually been imported 

 in some abundance by a collector, who sold his stock to 

 Messrs. Loddiges. 



83. LINDLEYA mespiloides. 



Humboldt Sf Kunth nov. gen. et sp. plant. 6. 239. t. 56^. 



This very rare and curious plant has just flowered in the 

 Garden of the Horticultural Society, where a single specimen 

 exists, which was raised sometime since from Mr. Hartweg's 

 Mexican seeds. It has something the appearance of Crataegus 

 mexicana, but has a dry capsular fruit. It proves evergreen, 

 and may possibly be hardy : but of that we have as yet no ex- 

 perience. Humboldt compares it for habit with the common 

 Apple, but it would be better likened to a small narrow-leaved 

 Medlar. 



84. SPIRANTHES rosulata. 



S. (Sarcoglottis) rosulata; foliis oblongis coriaceis rosulatis glabris, scapo 

 aphyllo hirsute 2-3-vaginato, spica ovata hirsuta, bracteis lineari-lanceo- 

 latis dorso glabris, labelli oblongi rotundati venosi ungue apice excavate 

 basi bicruri. 



A Guatemala plant, not unlike Spiranthes picta. It has 

 a scape about nine inches high, and a close spike of green 

 flowers. The leaves are most beautifully coated on the under- 

 side with vesicular cells, which give them a peculiar frosted 

 appearance. Mr. Hartweg sent it to the Horticultural 

 Society from Guatemala. 



85. EPIDENDRUM collare. 



E. (Aulizeum) collare ; caulibus fusifonnibus elongatis apice triphyllis, foliis 

 coriaceis canaliculatis patentibus, racemo laxo paucifloro, ovario cunicu- 

 lato, sepalis petalisque conformibus petaloideis lanceolatis, labello ovato 

 obtuso undulato apice recurvo basi trilamellato, clinandrio margine ele- 

 vate denticulate cincto. 



From Guatemala, where Mr. Hartweg found it. Its 

 stems are 18 inches long, strong and deeply furrowed. The 

 flowers are white, changing to yellow and brown as they go 

 off. The anther-bed is surrounded by an elevated edge,
