A STUDY IN ENDEMLSM. 2s!? 



father large leaves. Seeds very small and probably acciden- 

 tally carried. Common in the moist lower montane zone. 



46. Ehretia buxifolia, Roxb. (fide Trimen). Summit. Fruit 

 drupe, bird-carried, but common in dry zone. 



47. Didymocarpus Humboldtianus . Gardn. (fide Trimen ; 

 I did not see it). Summit. Seeds very small, but occurs on 

 rocks at Sigiri and other places in the dry zone. 



48. Wrirjhtia angustifolia . Thw. Summit. Seeds with a 

 bunch of hairs, wind- carried. Occurs in the dry zone, at 

 Dambulla, Anuradhapura, &c. 



49. Thunbergia fragrans. Roxb. var. parviflora . Trim. 

 (Journ. Bot. XXVII.. p. 165) Summit. Transport probably 

 accidental. None was noticed on the way up. but the type 

 occurs in the dry zone. The variety is endemic to Riti- 

 gala. 



50. Daedalacanthus montanm. And. Summit. Transport 

 method doubtful, but common in the dry zone. 



51. Stenosiphonium Russellianum , Nees. Summit, &c. 

 Common. Transport method doubtful. Common in the 

 dry zone. These specimens are thickly clothed with 

 glandular hairs, and thus differ considerably from all in the 

 Peradeniya herbarium excepting one sent in by Mr. Vincent 

 who reported on the Ceylon forests many years ago ; this 

 specimen is labelled by Trimen, Northern Province. 



52. Strobilanthes viscosus, And. (?) No flowers, so the 

 identification must remain uncertain. Captain Gage of 

 Calcutta also thinks it is this species. Summit. Means of 

 transport doubtful. Common in the montane moist zone 

 from 3,000 to 7,000 feet. 



53. S. stenodon, Clarke. Summit. Transport method 

 doubtful. Very rare in the intermediate district. Onh 

 recorded for Lagalla, and below Lakkaigala both in Mat ah- 

 East. The specimens from Ritigala probably represent a 

 local variety, the leaves being densely hairy below while the 

 Matale specimens are glabrous. But there is a solitary 

 specimen in the Peradeniya herbarium, from Lagalla in 1884.
