Peyr., E. nitidum Spreng. and E. hypoleucum Plowman. These 

 may all be readily distinguished from E. Leal-costae by their lack 

 of stipular striations. 



Erythroxylum (sect. Archery throxylum) occultum Plowman, sp. 

 nov. 



Arbor parva. Trunci cortex griseus, longitudinaliter et trans- 

 versaliter profunde fissuratus. Ramuli recti, lenticellis abundan- 

 ter producti. Stipulae persistentes, estriatae, nigrescentes, leviter 

 fimbriatae, 3-setosae. Folia persistentia, breviter petiolata; lami- 

 nae ellipticae vel oblongae, apice retusae, margine undulatae, basi 

 cuneatae, chartaceae, elineatae. Flores 1-2 in axillis ramulorum 

 hornotinorum producti, pedicellati. Petali lamina plus minusve 

 plana, oblongo-elliptica. Urceolus stamineus quam calyx paulo 

 brevior, ad marginem integer. Drupa oblongo-ellipsoidea, apice

TREE to 12 m. tall, with trunk reaching 35 cm. in diameter 

 {fide Coimbra). BARK on trunk of young tree roughish, irregu- 

 larly finely mottled with corky warts and fissures, dark reddish 

 brown; in mature tree deeply fissured transversely and longitudi- 

 nally forming quadrangular plates, dark grey {fide Coimbra). 

 BRANCHES ascending, spreading, somewhat storied, terete, 

 brown. BRANCHLETS distichous, consisting mainly of long 

 shoots, straight, diverging 45°-60° from axis, flattened toward 

 apex, 1.5-2.0 mm. in diameter, reddish brown, turning dark 

 brown or dark grey with age, covered with numerous punctate or 

 briefly elongate whitish lenticels. INTERNODES 2-18 mm. long. 

 RAMENTA produced brieflv at base of shoots for 5 8 mm. along 



stem, equaling the stipules. STIPULES persistent, appressed, 

 somewhat incurved with age, oblong to narrowly ovate, 1.2-2.3 

 mm. long, flrmly membranaceous, estriate, pale green, turning 

 dark brown or black with age, apically rounded to truncate, 

 3-setose, the setae subfilamentose, early caducous, the 2 lateral 

 setae I mm. long, the medial seta 0.5-0.8 mm. long, the keels 

 slender, fllamentose when young, the margin fimbriate when 

 young, becoming entire and somewhat involute with age. LEAVES 

 persistent, scattered on longer branchlets or 2-3 produced near
