57. ASCOTAINIA Ridl. 



The genus Ascotainia contains about three species: Ascotainia 

 penangiana Ridl. from Penang Hill, A. Hookeriana Ridl. from 

 Sikkim, and the following: 



1. Ascotainia Elmeri comb. nov. Tainia ~E\meri A??ws in Elmer's 

 Leaflets of Phil. Bot. 5 : 1570. 

 Luzon. 



58. SPATHOGLOTTIS Bl 



About thirty-five species from Java, Sumatra, Borneo, Malay 

 Peninsula, New Guinea, and Celebes have been described. The 

 distinguishing characteristics are not clearly understood, conse- 

 quently it is difficult to differentiate between the species which 

 have already been described. 



1. Spathoglottis aurea Lindl Journ. Hort. Soc. 5 : 34. This spe- 

 cies has been reported from the Philippines, but I have not seen 

 any material quite referable to it. S. Elmeri Ames is a near ally. 



2. Spathoglottis chrysantha Ames Orchidace^e 2 : 161. 

 Luzon. 



3. Spathoglottis Elmeri Ames in Elmer's Leaflets of Phil. 

 Bot. 5 : 1572. This species exhibits the tendency toward varia- 

 tion in the middle of the labellum which is characteristic of 

 S. aurea Lindl. In my herbarium a specimen from the type col- 

 lection has a linear middle lobe to the labellum without any 

 indication of lobules or dilation. The basal lobes and the calli 

 are smooth. The oblong lateral lobes serve to distinguish S. El- 

 meri from S. Kimballiana. 



Negros, Mindoeo? 



4. Spathoglottis Kimballiana var. angustifolia Ames var. nov. 

 Folia linearia, ± 40 cm. longa, 5-11 mm. lata, in sicco, valde ner- 

 vosa, 3-5-nervia. Sepala lateralia 2 cm. longa. Petala 2.5 cm. longa.
