arcuato-conjuncti; reticulum venularum praecipue subtus impressum. F lores e 

 trunco exeuntes; pedicelli recti, rigidi, ca. 3 cm longi et 2-3 mm crassi, apicem 

 versus paulo incrassati, dense ferrugineo-tomentelli, prope basin articulati. 

 Sepala in discum integrum 10-12 mm latum coalita, extus dense ferrugineo- 

 tomentella, intus glabra. Petala exteriora valvata, crassa, rigida, ovata, acu- 

 tiuscula, extus densissime sericea, intus breviter tomentella, 3-3.5 cm longa et 



2- 2.5 cm lata; petala interiora marginibus tenuibus imbricata, exterioribus ± 

 aequilonga, utroque latere breviter densissime cinereotomentella. Stamina nu- 

 merosissima, filamento 1-1.5 mm longo incluso 4-4.5 mm longa; connectivi 

 appendice truncato-semiglobosa minute papillosa; pollinis grana miniata. Ovaria 

 numerosa, sub anthesi non coalita, linearia, ca. 3 mm longa, dense ferruginea-

TYPE: VENEZUELA: Estado Bolivar, occasional in forest at Raudal Maraca 

 (about 110 river km from mouth), Rio Parguaza, elev. 115 m, Dec. 31, 1955, 

 /. /. Wurdack & J. V. Monacbino 41044. (NY). 



Unfortunately the material of this species is incomplete, as fruits are missing. 

 However the flower material is rich and it shows that the type belongs to the 

 genus Annona. According to the revision of the sections of Annona, published by 

 the author in Acta Horti Bergiani 10: 198 (1931) this new species must be placed 

 in section Eu-Annona, even if the pocket-shaped pits in the nerve angles on the 

 back side are very small. In the vegetative parts the new species agrees also 

 rather much with the section P sammogenia, especially in the impressed network 

 of the veins. However, the imbricate aestivation of the inner petals does not agree 

 with the valvate inner petals of P sammogenia. The most remarkable character 

 for the new species is the cauliflory, with the flowers situated on the stem. 



Duguetia venezuelana R.E.Fr., sp. nov. 



Frutex 9.3-1 m altus vel arbuscula ad 4 m alta; ramuli densissime aureo- 

 lepidota. Petiolus 2-5 mm longus; lamina rigida, supra -ab initio omnino glabra 

 et laevis, subtus lepidibus stellatis argenteis et margine tantum fimbriatis den- 

 sissime vestita, ovalia, basi brevissime acuta, apice rotundata vel breviter acu- 

 tata vel interdum minute emarginata, 4-6 cm longa et 2-3 cm lata; costa subtus 

 elevata. Pedunculi breves (ca. 5 mm longi), bractea minuta instructi. Sepala fere 

 libera, ovata, acutiuscula, extus densissime lepidota, intus pilis stellatis tomen- 

 tella sed basin versus glabra, ca. 1.5 cm longa et 1-1.5 cm lata. Petala extus 

 densissime stellato-lepidota, intus glabra sed apicem versus pilis stellatis tomen- 

 tella, exteriora rhombeo-spathulata ca. 2.5 cm longa et 1.5 cm lata, interiora 

 pau^p angustiora, oblongo-spathulata, ad 3 cm longa et 1 cm lata. Stamina 1.5-2 

 mm longa, connectivi appendice globosa, brevissime setulosa. (Fructus ignotus.) 



TYPE: VENEZUELA: Alto Rio Orinoco, Territoric Amazonas; locally occa- 

 sional in tree "islands" in Savanna No. 3, northwest base of Cerro Yapacana, 

 elev. 150 m, Mar. 17,1953, Bassett Maguire & John J. Vsurdack 34565 (Herb. Mus. 

 Holm.). 



Because the inner petals are narrower than the outer, this species ought to be 

 placed in section Heteropetalum. However, it recalls in its habit section Ew- 

 Duguetia (D. furjuracea and others) and it would perhaps be better to refer it to 

 that section. D. venezuelana is distinguished by the small, elliptic leaves, which 

 are rounded at the apex and quite glabrous above from the first. 



Duguetia dimorphopetala R.E.Fr., sp. nov. 



Frutex 1 m altus, ramuli novelli dense stellato-lepidoti. Petiolus crassus, 



3- 8 mm longus; lamina rigida, discolor, supra ab initio glabra, subtus primo 

 dense, demum laxe lepidibus margine fimbriatis vestita, ovato-oblonga, ca. ad
