monoecious but are frequently dioecious. There are no floral 

 or vegetative characters by which they may be distinguished. 

 In this connection it is well to call attention to the fact that the 

 drawing of the pistillate flower given by Pax and Hoffmann '^ is 

 erroneous in that the styles are shown as very short, obovate, 

 and 3-toothed. In this species, as in C. luzonicum and all of 

 the other indigenous ones of the genus found in the Philippines, 

 the three styles are elongated and cleft nearly to the base into 

 two long arms. In this character all of our indigenous species 

 of the genus differ from typical Codiaeum, and a more natural 

 arrangement would be their segregation as a subgenus or per- 

 haps even their separation generically from Codiaeum. 



CODIAEUM MACGREGORII sp. nov. 



Frutex vel arbor parva, ramulis inflorescentiisque exceptis 

 glabra; foliis lineari-oblongis, usque ad 30 cm longis, 3 ad 3.5 

 cm latis ; inflorescentiis 9 usque ad 45 cm longis, cinereo-pubes- 

 centibus; floribus 5-meris, sepalis dense pubescentibus ; ovario 

 dense hirsuto ; stylis 3, bifidis, elongatis ; capsulis dense hirsutis, 

 obovoideis. 



A shrub or small tree, the young branchlets and inflorescences 

 densely cinereous-pubescent with short subappressed hairs. 

 Leaves glabrous, chartaceous, linear-oblong, 30 to 40 cm long, 

 3 to 3.5 cm wide, their margins parallel, the base rather abruptly 

 acute or cuneate, the apex acuminate; lateral nerves 20 to 30 

 on each side of the midrib, spreading, anastomosing, distinct; 

 petioles 5 to 8 cm long. Pistillate inflorescences up to 45 cm 

 in length, solitary, subtended by an oblong, sessile leaf about 

 10 cm long and 3 cm wide. Flowers rather numerous, race- 

 mosely arranged, their pedicels 2 to 5 mm long. Sepals densely 

 pubescent, oblong-ovate, acute, about 2 mm long. Ovary very 

 densely hirsute; styles 3, glabrous, each cleft nearly to the 

 base into two 5-mm long arms. Young capsules obovate, about 

 7 mm long, rather densely hirsute with pale, stiff, spreading 

 hairs.

This species is well characterized by its elongated, narrow, 

 glabrous leaves and its rather densely pubescent inflorescences 

 and hirsute capsules ; the indumentum is entirely different from 

 that of C. ciliatum.
