216 BULLETIN JARD. BOT. BUITENZORQ, VOL. IV. LlVR. 1. 



Of the plants gathered m, Bornéo by NiEUWENHUiS (No. 1485) and 

 WlNKLER (No. 219Q, of which the Buitenzorg Herbarium possesses only 

 a duplicate) the former is too young for a thorough examination. Never- 

 theless it can easily be made out that the said former, on which Engler 



based the spécifie name, is a Homalomena, probably of the affinity 



of H. sagittifolia JUNGH. or a form of a it. WlNKLER's original No. 2129, 

 occurring in the Berlin Herbarium, is unknown to me, but the Buitenzorg 

 duplicate resembles in my opinion very much a plant cultivated in the Buitenzorg 

 Gardens under the name of Sch. novo-guineensis N. E. Br. ; it is disting- 

 uished by its maculate leaves, whilst in Sch. Nieuwenhuisii Engl. the 

 leaves are immaculate. 



There are in the Buitenzorg Gardens 2 beds (XI B: X 111, 160) with 

 absolutely différent Bornean plants cultivated both under the name of Sch. 

 Nieuwenhuissi Engl. whilst in another bed (XI B; X 1 13) is a plant of an 

 unknown locality, cultivated under the name of Sch. calyptrata Z. & M. 

 var. concolor but agreeing exactly with No. 160. Comparing them with 

 Engler's diagnosis and figure quoted above, it seems that No. 160, from 

 an unknown collector, has been the plant used by Engler for his diagnosis 

 and figure, and No. 111, collected by NiEUWENHUlS, must be renamed 

 and then the new diagnosis of Sch. Nieuwenhuisii ENGL. will be:

 cm. long, dark-green, minutelylongitudinallypale-puncticulate-striate, sheathing
