ing the species with more exactness, partly for the sake of 

 determining which of the garden plants are mere varieties, 

 and also with a view to the correction of a few errors. For 

 this reason the following enumeration of the species has been 

 prepared, in drawing up which I am most particularly in- 

 debted to Mrs. Lawrence, Mr. Rucker, and Messrs. Loddiges. 



*' Lahello apice integro. 



1. S. insignis (^ Frost in Bot. Mag. tt. 2948 & 9. Lodd. Bot. 



Cab! t. 1985. Lindl. in Bot. Reg. t. 1837. Gen. & Sp. 

 Orch. no. 1.) ; hypochilio globoso antice intruso basi et 

 apice fisso mutico intus radiatim verruculoso extus ecari- 

 nato epichilio sequali, epichilio subrotundo-ovato integro, 

 cornubus subtriangularibus falcatis incurvis brevioribus, 



columna latissime alata. Brazil. This species is 



remarkable for the globose form of the base of its lip, by 

 which all its varieties are readily distinguished. It is 

 also in almost all cases sprinkled with small violet spots, 

 which reach even to the tip of the labellum. In co- 

 lour, however, it varies very considerably. The winged 

 margin of the column is wider than in any other known 

 species. 



2. S. Devoniensis (Lindl. Sert. Orch. t. L S. maculosa, Floral 



Cabinet, t. 121 ? Maxillaria lyncea, Lindl. Gen. & Sp. 

 Orch. p. 151. Coatzonte Coxoahitl seu Lyncea, Hernand. 

 Thesaur. Rer. Med. Nov. Hisp. p. 9,6Q>. Anguloa Her- 

 nandezii, Kunth. Synops. 1. 332.) ; hypochilio subglo- 

 boso antice gibboso basi mutico epichilio sequali, epichilio 

 ovato integro v. obsolete tridentato, cornubus falcatis in- 

 curvis sequalibus, columna marginata. Mexico. 



Very much like S. tigrina, from which it is distinguished 

 by the undivided middle lobe of the lip, and the almost 

 wingless column. To >S'. insignis it approaches in form, 

 although so different in colour j but the lower half of the 

 lip is prominent in front instead of being pressed back- 

 wards. The flowers are yellow, with deep crimson-brown 

 blotches ; the lip is white with a few spots here and 

 there, and a deep purple stain over half the lower part. 

 Little doubt can be entertained that S. maculosa is a bad 

 specimen of this, for although its epichilium is described 

 as 3-lobed, it is represented as perfectly entire.
