ALABASTEA BORNEENSIA. 241 



the tube produced 4 mm., obscurely and broadly 6-toothed. 

 cylindric. Corolla-tube 10 mm. long, externally densely ap- 

 pressed pale-pubescent, the lobes 6, oblong, subobtuse. 7 mm. 

 long, somewhat spreading in anthesis, very much thickened 

 and keeled inside. Anthers 3 mm. long. Ovary 6-celled. 

 Fruit (immature) ovoid or ellipsoid, 2 cm. long, appressed- 

 pubescent, not at all sulcate, the pyrenes 30 to 40, all vertical 

 Bracteoles subtending the flowers and fruits two, linear-lanceo- 

 late, pubescent, about 5 mm. long. 



British North Borneo. Sandakan, Villamil 129, 252 

 bis (type), February 2 and November 25, 1916, in open places 

 and brush-lands, altitude 80 to 110 meters, flowers white, 

 fruits green. 



A species well characterized by its rather large, sessile or 

 subsessile leaves which are gradually narrowed to the slender 

 base, and its solitary, short-pedicelled, rather large, 6-merous 

 flowers. It apparently belongs in the group with Timonius 

 subsessilis, Val., but is not closely allied to this species or the 

 others placed near it by Yaleton, but seems to be closely allied 

 to Timonius palaivanensis, Elm., which was described from 

 staminate specimens. 



Timonius involucratus, sp. nov. 



Arbor, floribus f ructibusque exceptis glabra ; ramis ramu- 

 lisque teretibus; foliis coriaceis, ellipticis ad oblongo-ellipticis, 

 utrinque subaequaliter angustatis breviter obtuse acuminatis, 

 usque ad 18 cm. longis, petiolatis, nervis utrinque 6 ad 8 

 prominentibus, venis reticulatis, supra impressis, subtus valde 

 obscuris; stipulis late obovatis, rotundatis, 2.5 cm. longis, 

 imbricatis; fractious solitariis, brevissime pedicellatis, axil- 

 laribus, depresso-giobosis, junioribus 1.5 cm. diametro, extns 

 adpresse pubescentibus, pyrenis verticalibus, circiter 18, sepalis 

 persistentibus, inaequalibus, late ovatis, 7 ad 10 mm. longis; 

 bracteolis late ovatis, 2.5 ad 3 cm. longis, integris vel trilobatis, 

 in siccitate subcoriaceis, brunneis, obtusis, fructibus involu- 

 crantibus. 



A glabrous tree except the flowers and fruits. Branches 

 terete, reddish-brown, the ultimate ones about 3 mm. in 

 diameter, striate. Leaves coriaceous, elliptic to oblong-elliptic, 

 brown and slightly shining on both surfaces when dry, 10 to 18 

 cm. long, 5 to 10 cm. wide, subequally narrowed to the decur- 

 rent-acuminate base and the shortly blunt-acuminate apex ; 

 lateral nerves 6 to 8 on each side of the midrib, impressed 

 above, prominent beneath, curved, anastomosing, the reticula- 

 tions netted, impressed on the upper surface, rather close, very 

 obscure on the lower surface; petioles stout, 1 to 1.5 cm. long; 

 stipules brown when dry, subcoriaceous, broadly obovate, im-
