3, and occasionally, 2-4 not very strong costse in the upper surface, the 
secondary nerves very numerous and rather sharp on both surfaces, which 
therefore appear strongly striate; the terminal leaflets are of unequal 
width in the only leaf seen by me and not broader than the others, 
having 3-4 costse, are united only at their bases, and terminate in as many 
pairs of narrow teeth as there are costae; eacli pair of teeth is separated 
by a sinus 15-20 mm. deep. Male flowers lanceolate, acuminate, 3- 
gonous, more or less asymmetric, 3-3.5 mm. long; the calyx very small 
about 0.5 mm, long, its sepals triangular, acute, sharply keeled; the 
corolla many times longer than the calyx, its petals lanceolate, acuminate, 
strongly striate extornally; stamens G, with short filaments and very 
narrowly sagittate acuminate-apiculate anthers; the rudimentary ovary 
is a little longer than the stamens and is formed by 3 slender subulate 
bodies united only at their basal part. Fruiting perianth 8 mm. liigli. 
Fruit oblong-elliptical, almost equally narrowed at both ends, 18 mm. 
long, 7 mm. thick, terminating in a sharply defined disciform, orbicular, 
r 
3 mm. in diameter, mammillate surface, the remains of the 3 stigmas 
forming a small obtuse mucro in its center, otherwise the fruit is very 
similar to that of A. mammillata.

* 
I have described this species from very fragmentary material consisting of 
an entire leaf, detached male flowers and only one fruit, nevertheless A. Vidolhina 
seems to me to be a very well characterized species on account of its relatively 
large hexandrous male flowers and small elliptical fruit; it is related to A. mam- 
millata from which it differs in the broader 3-costulate leaflets, larger male 
flowers and in the fruit equally tapering to both ends.
