« Nota 4. Nomen synonymum Bhynchostele scribendum est, sie legimus in ßotan. Ztg. (1852) 

 770 (ubi diagnosis originaria) et in Walpers Ann. VI. 845 et in Benth. et Hook. f. Gen. III. 565. 

 In Indice Kewensi hoc nomen corruptum est in Rhynchostelis, quem errorem suseepit cl. R. 

 Schlechter in Bot. Centralbl. Beih. XXXVI. 509. 



Nota 2. Odontoglossum pygmaeum Lindl. publici juris factum est in Planus Hartwegianis

Nota. Hujus speciei iconem tantum analyticam et fragmenta pseudobulbi vidi. E doscrip- 

 tione et icone dilueidissime apparet, plantam esse Leochilum non Oncidium sensu restrictiore. 



Species e genere Leochilo exeludendae. 



L. diaphanus (Reichb. f.) Schlechter nov. comb. = Odontoglossum dw/phanum 

 Schlechter in Bot. Centr.-Bl. Beih. XXXVI. (1918) 508, est Oncidium diaphanum 

 Reichb. f. in Linnaea XU. (1877) 67 cf. supra p. 190 hujus libelli. 



Nota. Qua de causa cl. Schlechter synonymum novum i. e. Odontoglossum diaphanum 

 Reichb. f. constituerit, non est intellegendum. Reichenbach ipse in Linnaea 1. c. Oncidium 

 scripsit non Odontoglossum. 



L. Dignathe Schlechter, Orchid. (1914) 498 et in Bot. Centr.-Bl. Beih. XXXVI. (1918) 

 508 = Dignathe pygmaea Lindl. in Journ. Hort. Soc. Lond. IV. (18 49) 2 68; Reichb. f. 

 in Walp. Ann. VI. 682. 



Nota. Possideo iconismum ex herbario Lindley permissu benevolo autorilatum Kewensium 

 delineatum, qui etiam Reichenbachio notus fuit, e quo elucet Dignathen esse plantam adeo pe- 

 culiarem, quae optimo jure pro typo generis habenda sit. 



Hie addere juvat, quae de plantula seimus: -»Dignathe pygmaea Lindl. 1. supra c. — Pseudo- 

 bulbus squamatus, monophyllus. Flos solitarius, resupinatus, carnosus. Sepala et petala palentia, 

 aequalia. Labellum planum, recurvum, basi subsaccatum et per lamellas 2 carnosas columnae 

 adnatum. Columna nana, acuta, semieonica, clinandrio dorsali immarginata, anthera — ? pollinia 2, 

 caudicula lineari, glandula parva ovali. — Mexico. c 



Genus Pilumnae etAspasiae affine. Columna nana, clinandrio dorsali immarginato et habitu 

 quodam valde diversum. f »Inconspicuous. Whole plant is barely 2 inch. high and forms little tufts 

 like an Alemania or Dinema. Pseudobulbs oblong, buried in leathery, acute scales. The leaves 

 are solitary,*oval, stalkcd, 3-toothed at the point. Peduncle is solitary fromthe base ofthe pseudo- 

 bulb onefiowered, as long as the short keeled petiole. A keeled acuminate membraneus bract is 

 larger than the ovary. The tiny flower is green, fleshy with a few yellowish spots upon the 

 disk and the 2 sueculent plates that unite it to the column. Both plates and column are downy.«
