cillatis, longiuseule petiolatis, coriaceis, elliptico-obovatis, basi valde 
decurrentibus, apice breviter acuminatis ; venis utrinque circiter 25. 
Staminate inflorescences terminal, 20 to 30 cm long, the rachis, 
branches and branchlets strongly 4-angled, with grayish-brown tomentum, 
the branches of the rachis except near its apex verticillate or subverticillate 
in fonrs, those of the lowest whorl up to about 12 cm long, those of 
the second whorl about 8.5 cm long, the secondary branches opposite or 
subopposite, rarely alternate, variable in length, the lower about 2 cm 
long, tertiary branches about 1 cm long; all above measurements includ- 
ing flowers ; the flowers clustered at the apices of the tertiary branches, the 
pedicels stout, tomentose, about 0.5 mm long, the bracteoles ovate, obtusely 
acuminate, 2 mm long, densely pubescent on the outer surface; bracts at 
the base of the rachis very numerous (judging by their scars), caducous, 
coriaceous, the base ovate, 3 mm long, contracted into an acute acumen 
about 4 mm long: sepals 5, free, oblong to ovate, imbricate, obtuse or 
truncate at the apex, 1.5 to 2 mm long, ciliate; petals 5, imbricate, 
narrowly oblanceolate, up to 7 mm long, obtuse or barely apiculate at the 
apex, the margins usually inrolled, glabrous, the costa very conspicuous, 
otherwise veinless, at the extreme base more or less connate; fertile 
stamen one, its filament eventually exserted, up to 8 mm long, hardly 
dilated at the base, usually 4 staminodes of irregular shape 1.5 to 2 min 
long at the base of the petals, the bases of the petals, stamen, and sta- 
minodes forming a short floral axis around a minute disk: pistillate 
flowers unknown: fruit said to be similar to that of Mangifera indica , 
but larger, edible. 
Said to be a very large tree, with extremely poisonous juice; the 
ultimate branches rather obscurely tetrangular, with less conspicuous 
intervening ridges, 12 to 13 mm in diameter at the nodes, very con- 
spicuously marked by the scars of fallen petioles; bark greenish-gray, 
tomentellose or glabrescent: leaves in whorls of four; petioles 3.5 to 5 
cm long, 3.5 to 4 mm wide below the extreme base of the decurrent 
lamina, strongly dilated at the base ; lamina coriaceous, glabrous, narrowly 
elliptic-obovate to obovate, 12 to 16 cm long, 5.5 to 8 cm wide, the base 
acuminately long-decurrent, the margins revolute, the apex forming an 
obtuse acumen about 5 mm long; costa projecting slightly from the 
upper surface, 3 to 4 mm wide, with slender longitudinal ribs on both 
surfaces, usually only the latter projecting beneath ; pairs of veins 22 
to 28, rather straight except toward the apex, the connecting veins ob- 
scure but often fairly evident, one or two intervening veins often visible. 
Mindanao, Moro Province, Dapitan, Father Antonio Obach, S. J. This re- 
markable mango, communicated by Father F. Sanchez, of the Ateneo de Manila, 
seems singularly distinct in its verticillate leaves, but finds its closest alliance in 
M. caesia' Jack and M . superba Hook. f. Through Father Sanchez’ courtesy, I 
am enabled to quote the following, taken from an account of a trip of his own, 
near Dapitan, in February, 1892.
