I have placed it in the latter section, from which it differs in its 

 deeply lobed leaves, more numerous stamens, and its cocci not appendaged. 

 Macaranga caladiifolia Becc. is well represented by 167, lJt32, and 1511 of 

 the same collection. 



MOULTONIANTHUS genus novum 



(Ewphorbiceae-Cluytieae-Clutiinae) 



Flores monoici, petaligeri, racemosi. Sepala $ 5, imbricata, 

 libera. Petala 5, calyce multo longiora. Disci glandulae nullae. 

 Stamina 8 vel 10, 2-verticillata, libera, antherae dithecae, intror- 

 sae, longitudinaliter dehiscens, filamenta brevissima. Ovarii 

 rudimentum evolutum. Sepala 9 5, imbricata, libera. Petala 

 5, elongata. Disci glandulae nullae. Ovarium 3-loculare; styli 

 liberi vel basi brevier connati, bifidi ; stigmata papillata ; ovula in 

 loculis solitaria. Frutex vel arbor parva. Folia alterna, pen- 

 ninervia, breviter petiolata, obscure crenata; stipulis ovatis, 

 profunde cordatis, persistentibus. Racemi axillares, elongati, 

 flores s numerosi, secus rachin fasciculati, $ pauci, solitarii, 

 longissime pedicellati. 



MOULTONIANTHUS BORNEENSI8 sp. nov. 



Frutex vel arbor parva inflorescentiis exceptis glabra; foliis 

 oppositis, oblongis ad oblongo-ellipticis, coriaceis, usque ad 25 cm 

 longis, apice late obtuse acuminatis, basi rotundatis, nervis utrin- 

 que circiter 10, prominentibus ; stipulis 1 ad 4 cm longis, folia- 

 ceis; inflorescentiis $ racemosis vel depauperato paniculatis, 

 usque ad 12 cm longis, multifloris, floribus tenuiter pedicellatis, 

 fasciculatis ; racemis $ elongatis, paucifloris, floribus longissime 

 pedicellatis. 



A shrub or small tree, glabrous except the inflorescence. 

 Branches terete, slender, smooth, pale- to dark-brown when dry. 

 Leaves opposite, oblong to oblong-elliptic, coriaceous, brown and 

 shining when dry, 12 to 25 cm long, 5 to 9 cm wide, base equilat- 

 eral, rounded, apex prominently but broadly blunt-acuminate, 

 margins distantly crenulate or dentate-crenulate ; lateral nerves 

 about 10 on each side of the midrib, prominent, obscurely anasto- 

 mosing near the margins, the reticulations obscure; petioles 5 

 mm long or less; stipules foliaceous, coriaceous, persistent, 

 orbicular to ovate, 1 to 4 cm long, rounded to obtuse, base deeply 

 cordate and clasping the stem. Racemes axillary, solitary, or 

 sometimes one staminate and one pistillate in the same axil, 

 sparingly pubescent. Male racemes many flowered, up to 12 cm 

 long, sometimes developed into a depauperate panicle by short 

 branches in the lower part. Flowers fascicled along the rachis, 

 their pedicels up to 10 mm in length, slender, each fascicle sub- 

 tended by several ovate, somewhat ciliate, 1 mm long bracteoles.
