mg the species with more exactness, partly for the sake of 
determining which of the garden plants arc 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 wdiich I am most particulaily in- 
debted to Mrs. Lawrence, Mr. Rucker, and Messrs. Loddiges. 
* Labello 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 hasi et 
apice fisso mutico intus radiatim verruculoso extus ecari- 
nato epichilio sequali, epichilio subrotundo-ovato integro, 
cornubus subtriangularibus falcatis incur vis hievioiibus, 
columna latissime alata. Brazil. Fhis 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. 1. S. maculosa , Floial 
Cabinet, t. 121 ? Maxilla: ria lyncea , Lindl. Gen. & Sp. 
Orch. p. 151. Coatzonte Coxoahitlseu Lyncea , Hernand. 
Thesaur. Rer. Med. Nov. Hisp. p. 266. Anguloa Her- 
nandezii, Kunth. Synops. 1. 332.) ; hypochilio subglo- 
hoso 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 ; 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.
