MR. CHARLES HOSE'S BORNEAN MONOCOTYLEDONS. 



By a. B. Rendle, M.A., D.Sc. 



The following is a list of the Monocotyledons contained in 

 collections made by Mr. Charles Hose in the Baram district of 

 Sarawak in the years 1894-95 ; including also a few collected in 

 the Minahasa district of North Celebes. The plants are in the 

 National Herbarium. 



Burmannia coelestis Don. 



Baram, Nov. 1, 1894 ; no. 353. 



Oheronia iridi folia Lindl. 



Baram, Nov.' 10, 1894; no. 151. 



Not hitherto recorded from Borneo, though known from India, 

 the Philippine Islands [Cuming y nos. 2120, 2137), and Australia. 



Oberonia Hosei, sp.nov. Herba breviter caulescens, foliis 

 distichis brevibus ensiformibus subacutis ; scapo bracteato, cum 

 racemo gracili folia diiplo excedente ; floribus minimis, spiraliter 

 ordinatis, haud densis ; bracteis oblongo-lanceolatis acuminatis, 

 margine erosis, pedicellum cum ovario paullo superantibus; sepalis 

 late ellipticis obtusis integris, siccis reflexis ; petalis ovatis, sepala 

 subsequantibus, marghie erosis; labello aurantiaco concavo 3-nervio, 

 e basi auriculata superne paullo angustato, apice bifido, lobis acutis. 



Plant 12 cm. high, with a short erect stem barely 2-5 cm. long 

 bearing 8 distichously arranged leaves, tlie largest 4-5 cm. long by 

 •5 cm. broad. Scape sheathed at the base by the uppermost leaf, 

 bearing only small membranous acute bracts in the lower part (2*5 

 cm.), fertile portion 7 cm. long ; the minute orange-coloured flowers 

 aggregated in groups of threes, becoming solitary above. Bracts 

 1-25 mm. long; flowers subsessile, pedicel and ovary together 

 1 mm. long ; flower when spread open 2 mm. across. Sepals 

 •75 mm. long. Lip 1 mm. long by -75 mm. broad at the base, 

 apparently a deeper orange than the rest of the flower, narrowing 

 slightly from below upwards, bifid at the apex for about one-third of 

 its length, with an obsolete lobule between the triangular segments. 



Is perhaps nearest the Silikim species 0. auriculata King & 

 Pantling, from which it differs in its orange flowers, more densely 

 arranged on the raceme, with broader petals, and especially in the 

 lip, which is broader at the base and less deeply cleft. 



Baram, Nov. 10, 1894 ; no. 80. 



Liparis Jfaccida Reichenb. f. 



Baram district, Entoyut river, Nov. 13, 1894 ; no. 459. 



Platyclinis brevilabrata, sp. nov. Planta minor rhizomate 

 subrobusto; pseudobulbis fusiformibus flavis, siccis corrugatis; foHo 

 lineari-lanceolato obtuso, breviter petiolato ; scapo tenui, folium 

 superante, e basi vaginata florifero ; racemo multifloro, floribus 

 parvis; bracteis latis truncatis pedicellos breves subaequantibus ; 

 sepalis obtusis, subaequalibus, dorsali oblongo-subspathulato ; 

 lateralibus oblongo-lanceolatis; petalis linearibus, inferne paullo
