on the upper surface. Sepals greenish. Petals yellow internally, virides- 

 cent externally, not white ! Stamens yellow ; anther yellow-purpurascent. 

 Ovary viridescent-yellow. Flowers July. 



I have a living specimen before me, by the kindness of Viscount Y. 

 Matsudaira, who collected it on Mt. Amagi in the province of Idzu, where 

 it was found growing on the large trees. 



MIYOSHIA Makino gen. nov. (PI. V.) 



Perianth perigynous, 2-seriate, persistent ; tube ; lobes short, im- 

 bricated, erect-patent or patulous, the sepals smaller. Stamens 6, 2-seriate, 

 equal, all perfect, the oppositisepalous 3 free, the oppositipetalous 3 shortly 

 adnate to the base of petals at the base ; filament subulate ; anther 2-celled, 

 rounded-ovato, introrse, dehiscing longitudinally, basifixed ; pollen yellow, 

 oblong. Ovary semi-inferior, 3-locular, the loculament opposite to the sepals, 

 the superior free portion entirely separated into 3 parts, each short-conical, 

 opposite to the sepals ; style short ; stigma terminal, simple ; ovules many in 

 each loculament, pluri-seriate along the elongated placenta, sessile, anatropous. 

 Capsule semi-inferior, accompanied by the peristent perianth, dehiscing loculi- 

 cidally through the ventral suture of the superior free portion. Seeds minute, 

 many, sessile, ferruginous, with the transparent thinly membranaceous loose 

 outer coat ; the inner coat longitudinally striate, adherent to the nucellus ; 

 endosperm copious ; embryo very minute. 



Saprophytic small aphyllous quite glabrous terrestrial perennial, destitute 

 of chlorophyll. Khizome hypogteous, shortly elongate, ascending, squami- 

 gerous, with fibrous roots. Scape gracile, slender, simple, provided with 

 membranaceous sparse scales. Inflorescence terminal, more or less panic- 

 ulated raceme ; bract small ; bracteoles often with the minute unexpanded 

 flower-bud. Flowers regular, hermaphrodite, small, pedicellate, laxly dis- 

 posed, quite glabrous ; pedicel arising from the axil of bracts. 



This genus seems to be nearly related to Aletris of Liliacece, but the 

 saprophytic, entirely glabrous, leafless, non-chlorophyll habit ; ovary which is 

 separated in the superior free portion ; and perianth destitute of the free tube, 

 are the principal characters to separate this plant from that genus ; it is 

 perhaps better to establish for it a new family, Miyoshiacece, having 

 affinities to Liliacece, Bromeliacece, Hcemodoracece, and Amaryllidacece. 



I have proposed to dedicate this genus to Dr. Manabu Miyoshi, Pro- 

 fesser of Botany in the Science College, Imperial University of Tokyo.
