Tribe 4. — Opheyde_*j. Anther terminal, erect (adnata to the top of 



the column). 

 Tribe 5. — Arethuse.e. Anther terminal, operculate (over the 



rostellum). 

 Tribe 6. — Nelittiejs. Anther dorsal (behind the rostellum). 

 ir. — Anthers two or three (Abnormal Tribes). (Diandr.e). 

 Tribe 7. — Cypeipedie.i;. Ovary one or three-celled. 

 Tribe 8.* — Apostasie.i:. Ovary three-celled. 



The. Genera and Species and the Folia U/'chUlar/'a reniained the 

 authoritative systematic treatises on the Orchide.e till the s\iliject was 

 taken in hand by Benthani for the Genera Phaifarum, although 

 Reichenbacli had compiled a synopsis of the Order Avith the exception 

 of tlie Tribe Cypripedie.e in Walper's Annales Bofanices Si/sfemafirte 

 published during the years 18G1 — 66. This synojisis was worked out 

 mainly on the lines laid down by Lindley, the whole of wliose Folia 

 Ordiidarea was incorporated in it, together with much fresh material 

 that had been placed within the author's reach. It pr()\'ed for the 

 time a valualjle source of reference for botanists. 



llentham also elaborated the ORcniDEiE on tlie Liudleyan system 

 witli a few modifications of tlie Tribal divisions founded chiefly upon 

 tlie characters of tlie appendage of the pollinia to which Lindley a[>plied 

 the common name of caudicle, Init as already pointed out, he applied it to 

 three very different parts of the pollinary aijparatus.f As the distinction 

 set up by Tandley lietween the Tribes Mai.axtoe-K and Epidendre^ 

 cannot be maintained Bentham has merged the first-named into 

 Epidendre/E. He has also merged Arethuse.e into Xeottie.k on the 

 ground that " the separation has proved to be purely artiticial without 

 even the advantage of a constantly definite, distinctive character. i And 

 lastly the small anomalous Tribes CYPniPEoiEa-: and Ai'ustasie.e are 

 consolidated into a single one. 

 Mr. Bentham^s Tribal divisions therefore stand thus : — 

 Tribe 1. — Epidendrei:, includino' Lindley's Malaxide.k. 

 Tribe 2. — A'ande.e, co-extensive with Lindley^s Yande.k. 

 Tribe 3. — Neottie^, including Lindley^s Arethcse.t^:. 

 Tribe 4. — Ophryde^, co-extensive with Lindley's Ophrviie.e. 

 Tribe 5.— Cypripediea', enlarged by the addition of the anomalous 



genera Apostasia and Neuwiedia.
