204 MERRILL. 



lanceolate, thickened, acuminate, 3 mm long lobes or teeth, these teeth 

 narrow and keeled on the inside. Petals 5, glabrous, in bud strongly 

 rostrate, imbricate, elliptic-ovate to elliptic-oblong, sliglitly inequilateral, 

 acuminate, about d mm long, » to 6 mm wide. Stamens about 65, 

 1-seriate, subequal, the filaments slender, more or less coherent below 

 in five plialanges, some or all ultimately free or nearly so, 7 to 8 mm 

 long, glabrous; anthers nan-owly linear-oblong, terete, straight or nearly 

 so, erect, in bud inflexed, gradually narrowed, to the base, about 5 mm 

 long, 0.5 mm in diameter, the connective not produced, appendages none, 

 opening by two terminal slits, each cell prolonged into a 0.5 mm long, 

 compressed tube, slightly obliquely tmncate. Ovary adherent to the 

 calyx, 5-celled, the ovules indefinite, on all sides of the thickened 

 placenta which is attached in the lower inner angle; style elongated, 

 i-ather stout, about 12 mm long; stigma 0.5 mm in diameter, punctiform. 

 Fruit unknown. 



Luzon, Province of Camarines, near Daet, For. Bur. lJf3.'f9 his Aguilar, July, 

 1909, in forests near the Maniba River (type) : Province of Laguna, Dajican, 

 Bur. Sci. 8983 Foxworthy, July, 1909, altitude about 300 m. 



Aguilar states that the flowers are red, and his specimens bear open flowers; 

 Foxworthy states that they are f^reonish-white, but on his specimen the flowers 

 are not quite mature. The diameter of the trunk is given by Aguilar as 27 cm, 

 and by Foxworthy as 25 cm. 



This new genus belongs in the Astronieae, and is perhaps most closely allied 

 to the Bornean monotypic genus Plethiandra. It is, however, very different from 

 that genus and from all others in the tribe and family. Characteristic features are 

 its prominently 5-lobed star-shaped calyx, and especially its very numerous 

 stamens, the anthers being slender and gradually narrowed to the base, opening 

 by two terminal slits, the cells being produced into very short, compressed tubes, 

 the connectives not produced and in no way appendiculate. 



In the entire family the only genera previously known in which numerous 

 stamens are found are tlie Bornean Plethiandra, mentioned abpve, and the Amer- 

 ican ones Calyptrella and Miconia.
