4IO ORCHIDS 



Otochilus. 

 and is in reference to the ear-like appendages at the base 

 of the lip. Flowers loosely racemose ; sepals and petals 

 almost equal, free, narrow, spreading ; lip sessile at base 

 of column, saccate at base. The species belonging to 

 this genus are rarely seen outside botanic gardens. 



PACHYSTOMA. 



As understood by Kew, this genus of terrestrial Orchids, 

 belonging to the tribe Epidciidrecs, does not include 

 Ipsea — a plan that has been followed in this work. 

 Blume's name is from padiys, thick, and stoma, a mouth, 

 in allusion to the thick lip. The species are natives of 

 tropical Africa, the East Indies, and the Malayan 

 Archipelago. Flowers mediocre, or rather large, pendulous, 

 in a simple raceme ; sepals connivent, the lateral one 

 sometimes \exy shorth' adnate to the base of the column ; 

 petals similar to the lower sepal, but smaller ; lip affixed 

 to, or adnate to, the base of the column, the lateral lobes 

 oblong and erect, the middle one short. Probably the only 

 species in cultivation is P. Tlionnoniana (Rchb. /.). This 

 is rarely met with outside botanic collections. The cultural 

 requirements are the same as those recommended for the 

 small-growing section of Ccvlogyjic, better known in gardens 

 as Plcionc. 



P. Fortune! {Rilib. /.). — A synonym of Spathoglottis Fortunei. 



P. speciosum {Rchb. f.). — A synonym of Ipsea speciosa. 



PALUMBINA {Rchb. /,). This is now merged with 

 Oncidium. 



PAPHINIA (LiiidL), This is now included under Lycaste. 



PARADISANTHUS. 



Reichenbach's ( pi/s) name for a small genus of Orchids 

 belonging to the tribe J^aiidcu-. It is derived from 

 Paradcisos, park, Paradise, and anthos, a flower, and is 

 in reference to the beauty of the plant. Flowers white, 

 curiously striped with deep purple ; sepals oblong-lanceolate, 

 acute, the two lateral ones slightly unequal at the base ; 

 lip shortly clawed, often pendulous ; pollen-masses four,
