I have thought it advisable to give Griftlth's charncter in full , as I find it docs not 

 correspond wilh my disseciions, though in othor respects ihe plant seems idenlical. 

 The fullowing are the noies made while examinitig ihis plant. Periaiith connivent.

 glands of the caiidicuia become altached. Ovary 1 celiod, placoniiferous margins

 dicula. In both rcspecls ihc drawing is wrong as wih bc al once observod on com- 

 paring fig. 7. with Ihe anthers of lig 6. which are correcily shown 1 colled, bul di- 

 laicd aiid ventricose below to ciiclose tlie iarge pollinia. In oilier rcs|>ects ibe 

 drawing is correct. 



According to Mr. Giiffitb's charncter thcre is only one perfcct stnmen „nnihor pa- 

 rallel wiih Ihe column. dorsal. Ilesliy . prolongod iiilo a long beak." In pLco of otie 

 1 find 3 such anthers. Cnn it be tluit as cora|tnrod with niine , his plants were to that 

 extfiii deficient. or were ihe anierior anthcrs ovorlookod in a huiried disstciion? In 

 eilher case it is extraodinary, fiist. as ii scems improbable tbat iwo pl;inis lo all api»ear- 

 ance so perfcclly idenlical. shouid difror so widely in so cssential an orgun; and se- 

 condly it seeiiis nboul oquatly improbnble ihat such an accurate ob.sorvor as Giiflilh 

 should commit such an ovorsighi. But coiisidering ihe former ihe more improbable 

 of Ihe two. I may remnrk tliat Ihis seems one of ihe niost curious of Orchidoous 

 planls. It hns 3 porfecl sinmens rinnishod wiih concnve pollen aiid iliese attnched to 

 a caudiclc and gland like those of Vandeae. Lindloy rejects Apostasieae as a genus 

 of Orchideoe; iliis secnis an equaily anoinalous plant ; can it also be similarly re- 

 jeciod so as in thnl way lo presorve ihe symmetry of the ordcr. For myself I 

 think not.
