54 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



been repeatedly introduced into cultivation; yet no one seems to 

 have given critical study even to these culti\ated plants. 



The African analogues of Orchyllium are confined to the moun- 

 tains of the mainland and islands of the gulf of Guinea; twp species, 

 Utrictdaria Mannii Oliver and U. bryophila Ridley, have been 

 described, and both are recognized in the "Flora of tropical 

 Africa," but they are probably not distinct. All the material of 

 both so-called species in the herbaria of the world could probably 

 be mounted on a single sheet of standard size without over- 

 lapping. Enough is known of this group to indicate a valid genus, 

 but not enough to characterize it properly; for the present it is 

 referred here, but no attempt has been made to include it in the 

 characterization of the genus Orchyllium. 



9. Stomoisia Raf. FI. Tellur. 4: io8. 1838. (? Trixapias Raf. 

 1838; ? Askofake Raf. 1838; Nelipus Raf. 1838; Enskide Raf. 

 \%^^; PersonulaYLdii. 1838.) Herbae scaposae terrestres, ramulis 

 brevibus radiciformibus et stolonibus tenerrimis foliatis a basi scapi 

 radiantibus, radicibus veris nullis. Folia diftormia, alia erecta et 

 viridia, linearia vel sublinearia, alia subterranea et radiciformia, 

 ascidiifera. Ascidia minuta, valde reducta, rostrata. Scapus 

 erectus vel flexuosus vel tortilis, squamatus, bracteatus, i-multi- 

 florus; squamae basifixae; bracteae basifixae; bracteolae consimiles 

 sed angustiores interdum filiformes. Calyx 2-partitus; lobi tenues, 

 venosi, superior plerumque major, capsulam arete amplectentes, 

 saepe accrescente valvati. Corolla xanthica vel cyanica, profunde 

 2-labiata; labium superius distincte unguiculatum, inferius gale- 

 atum, cum margine plus minus expanse; palatum praeter galeam 

 nullum; calcar conicum, pendens. Antherae bilobatae. Capsula 

 subglobosa, stylo persistente rostrata, calycis lobis arete inclusa. 

 Semina subglobosa vel prismatica, areolata vel reticulata. 



Species typica, Stomoisia cornuta (Michx.) Raf. {Utricidaria 

 corniita Michx.). 



This genus, of about 50 or more species, is widely distributed in 

 southern Asia, in Africa and Australia, and in eastern North and 

 South America; it is lacking in Europe, northern Asia, and through- 

 out the Andean region. With the exception of Utricidaria and 

 perhaps Calpidisca, it is the largest genus of the family. It is 

 strikingly characteristic in habit, and usually readily recognizable 

 at a glance. Most of the species have yellow corollas, strongly 

 laterally compressed, and the galeate lower lip is a prominent 

 feature in all.
