Byrsonima. 759 



loculos subduplo superante, ovario glaberrimo. — British Guiana, Schomburgk, 

 single specimen. — Species primo intuitu ab icone B. nitidissimae Kunth haud absimilis, 

 sed folia basi acuta et subtus glaberrima. Frutex videtur ramosissimus. Ramuli no- 

 velli rufo-villosi, mox tarnen glabrati. Folia 2 — 3 poll. longa, iy 2 — 2 poll. lata, obtusa 

 v. brevissime et obtuse acuminata, venis primariis a costa valde divergentibus numerosis. 

 Petioli 2 — 3 lin. longi. Stipulae parvae. Racemi 3 — 5 poll. longi, pedunculo, rhachi 

 pedicellisque dense ferrugineo-villosis. Bracteae persistentes 1 — 1 y 2 lin- longae, crassius- 

 culae, pubescentes, apice recurvae, inferiores saepe in foliolum petiolatum 2 — 3 lin. longum 

 excrescentes. Braeteolae consimiles sed minores. Pedicelli breves, recurvi, sessiles soli- 

 tarii v. gemini. Calycis laciniae extus dense rufo-villosae. Petala paullo majora iis B. 

 densae. Annulus stamineus dense rufo-villosus. Antherae iis B. densae subsimiles, loculi 

 tarnen ratione connectivi majores. Drupa fere globosa, glabra, 3 lin. diametro. 

 Nota. Hanc speciem supra sub n. 68 in seriem Platylepidem inserui.

 sonima; sed phrasi breviori species a plerisque glabrifoliis vix distinguenda. «

6. B. nitida (Ruiz et Pavon) G. Don Gen. hist. I. (1831) 636. — Malpighia 

 nitida Ruiz et Pavon Fl. per. vol. icon. — "Leaves ovate-oblong ; racemes terminal 

 and axillary, branched, panicled; petals fringed; fruit large, 3-seeded; stigmas 3. "|). S. 

 Native of Peru. — Shining leaved Byrsonima. Shrub 10 feet." 



7. B. ophiticola Small in Bull. Torrey Bot. Club XLIII. Nr. 9. (1916) 456. — 

 w Tree up to 8 m tall, the twigs with dark gray bark, the young tips with dark red 

 pubescence. Leaves clustered at the ends of the twigs, 3 — 6,5 cm long, blades spatulate 

 to narrowly obovate, rounded or obtuse at the apex, closely finely pubescent when 

 young, sparingly pubescent when full-grown, dull, paler green beneath than above, acute 

 or acuminate at the base, rather long-petioled ; panicles 5 — 9 cm long, bracts less than 

 3 mm lg., pedicels closely pubescent, at least in anthesis; sepals ovate or oblong-ovate, 

 2,5 — 3 mm long, obtuse or acutish, the glands mostly less than one half as long as 

 the sepal-body; petals yellow, turning to scarlet, 8 — 10 mm long, blade broadly reni- 

 form or orbicular-reniform, 7 — 8 mm wide, claw storter than the blades. 



Serpentine slopes, Guanajibo near Mayaguez (Britton, Gowell, and Brown 

 n. 4350). Related to B. lucida DC., from which it differs in the longer petioles, larger 

 panicles, and larger flowers. The petals besides unfolding yellow and turning scarlet, 

 have relatively shorter claws and more broadly reniform blades than in B. lacida, and 

 are of very firm texture and more persistent.
