ME. G. BENTHA.M ON ORCHIDE^i. 287 



I shall follow up this summary or conspectus with a few ob- 

 servations on the most important tribual and subtribual cha- 

 racters, and on the exceptions to them which have come under 

 my notice, and on the genera I would include under each. 



Conspectus tbibuum (exceptis neglectis). 



Tribus 1. Epidendre^e. Anthera 1, postica, opercularis, ssepius in- 

 cumbens, loculis distinctis parallelis. Pollinia cerea, 1-2-seriata, parallela, 

 in quaque serie 2 v. 4 (in quoque loculo 1-4), libera v. visco pareo v. 

 appendicula granulosa in quoque loculo connexa, rarissime v. casu tantum 

 rostello affixa. 



Subtiibus 1. Pleurothallece. Caulis ebulbosus, folio unico et inflores- 

 centia terminatus. 



Subtiibus 2. Microstylece. Anthera erecta v. prona, saepe persistens nee 

 incumbens. 



Subtiibus 3. Liparideee. Inflorescentia terminalis. Pollinia 4, rarius 8, 

 subaequalia, eonferta, ssepius libera, inappendiculata. 



Subtribus 4. Dendrobiece. Inflorescentia lateralis v. pseudoterminalis v. 

 in scapo distincto aphyllo. Pollinia 4, rarius 2, 1-seriata, parallela, in- 

 appendiculata. 



Subtribus 5. Eriece. Inflorescentia lateralis v. pseudoterminalis v. in 

 scapo distincto aphyllo. Pollinia 8, subaequalia, eonferta, vix v. non 

 appendiculata. 



Subtribus 6. Bletiece. Inflorescentia lateralis v. rarius terminalis. Pol- 

 linia 2-seriata (rarius 1-seriata), in quaque serie 4, parallela, omnia ascen- 

 dentia, appendicula granulosa connexa. 



Subtribus 7- Coclogynece. Inflorescentia terminalis. Pollinia 8 v. 4, 

 subaequalia, eonferta, visco v. appendicula parca connexa. 



Subtribus 8. Stenoglossece. Inflorescentia terminalis. Pollinia 4, 6, v. 8, 

 in locellis distinctis 1 -2-seriata, libera v. visco tenui connexa. 



Subtribus 9. Lceliea. Inflorescentia saepissitne terminalis. Pollinia 

 1-2-seriata, in quaque serie 4, collateralia, parallela, compressa, appendi- 

 cula granulosa connexa, inferiora ascendentia, superiora dum adsint 

 descendentia. 



Tribus 2. Vande^e. Anthera 1, postica, opercularis, rostello incumbens 

 v. applicita, loculis sub anthesi ssepissime confluentibus. Pollinia cerea, 

 saepissime 2 oblique v. transverse sulcata, v. 4 per paria sibimet applicita 

 linea transversa separata, anthera dehiscente (saepius jam in alabastro) 

 rostelli processu (glandules v. stipiti) sigillatim v. per paria affixa, quocum 

 pollinarium deciduurn formant. 



Subtribus 1. Eulophiece. Folia pseudobulborum plicato-venosa. Scapi 

 florentes apbylli v. foliati. Labellum calcaratum. 



Subtribus 2. Cymbidiece. Folia pseudobulborum plicato-venosa. Scapi 

 florentes aphylli v. foliati. Labellum ecalcaratum. Columna saepissime
