7. Calyptranthes macrophylla Berg in Mart. Fl. Bras 14: 1 45. 1857. 



For description see Berg, I.e. Amazonian Brazil (the type from Ega on the 

 upper Amazon ) to Venezuela.

8. Calyptranthes multiflora Berg in Mart. Fl. Bras 14: 1 42. 1857. 

 ?C. poeppigiana Berg, I.e. 45. 



Closely related to C. florifera MeYaugh, and discussed above under that 

 species. For description see Berg, I.e. Amazonian Brazil and Pern to eastern 

 Colombia and southern Venezuela. Type from Ega [Teffe], Brazil. For key to 

 the position of this species in the Peruvian flora, see Fieldiana Bot. 29: 178(1956). 



9. Calyptranthes ovoidea MeYaugh, sp. nov. 



Arbor velutina, ramnlis exalatis; foliis 6-8.5 cm longis ovatis vel ellipticis, 

 acuminatis, petiolis 6-7 mm longis ; nervo medio utrinque convexo ; alabastris 

 4-5 mm longis hirsutis, anguste ovoideis, elausis, calyptratis ; paniculis 3-5-floris. 

 pednnculis 3-6 mm longis. 



A tree, with young shoots, inflorescence, and petioles veliitinons. the sharp 

 lustrous somewhat flexnons pale brown hairs 1-1.5 mm long, the surface of the 

 young leaves, buds, and inflorescence completely covered ; leaves ovate or elliptic. 

 2.5-3.7 cm wide, 6-8.5 em long, 2-2.5 times as long as wide, acuminate, acute at 

 the base, the margins deenrrent on the verrneose, shallowly channeled petiole 

 1 mm thick, 6-7 mm long; midvein convex, about equally elevated on the two 

 surfaces; lateral veins 20-25 pairs, very slender and with numerous intermedi- 

 ates, scarcely apparent ; marginal vein about equaling the laterals and scarcely 

 arched between them, 0.5-1 mm from the margin ; mature blades dull and nearly 

 featureless above, finely dark-dotted beneath ; inflorescence axillary, glomerate, 

 consisting of paired reduced 3- to 5-flowered panicles in each axil ; flowers sessile, 

 the 3 central ones in a terminal cluster on a peduncle 3-6 mm long, the 2 lateral 

 flowers, if present, at the base of the peduncle; bracts ovate or lanceolate, 1.5-2.5 

 mm long, deciduous at an thesis; buds narrowly ovoid, hirsute, 4-5 mm long ; 

 hypanthium at anthesis 2 mm high, glabrous within; ealyptra 3 mm long, and 

 3 mm across the orifice, with a stout apiculum 1.5 mm long (the size and shape 

 of the apiculum complete^ obscured by the covering of hairs) ; plants dioecious 

 (?), the style in staminate flowers less than 1 mm long, apparently abortive; 

 functionally pistillate flowers not seen ; stamens about 100. 3.5 mm long, the 

 anthers 0.3 mm long ; petals none. 



A most distinctive species, known from but a single collection in which the 

 buds are beginning to open. The collector noted that the plants were apparently 

 dioecious, and this seems to be confirmed by the want of a style in the staminate 

 flowers.
