BRITTON: STUDIES OF WEsT INDIAN PLANTS 337 
Forest near the summit of Mount Tocuche, Trinidad (Britton, 
Hazen and Mendelson 1243). In fruit April 5, 1920. 
Specimens collected by J. Dannouse at Guanapo, Trinidad, 
showing imperfect flowers about 1 cm. wide (Trinidad Herb. 6415) 
are probably referable to this species. 
Chrysophyllum (?) minutiflorum sp. nov. 
A tree about 15 m. high, the young leaf-buds puberulent, 
otherwise glabrous. Leaves thin-chartaceous, oblong-lanceolate, 
13 cm. long or less, 2.5—5 cm. wide, long-acuminate at the apex, 
narrowed at the base, delicately pinnately and reticulate-veined, 
the rather slender petioles 10-15 mm. long; flowers green, several 
to many in sessile axillary fascicles; bractlets minute; pedicels 
very slender, thickened upward, 5-8 mm. long; calyx about 1.5 
mm. long, its 3 or 4 lobes rounded; corolla-segments 3 or 4, 
minute; stamens 3 or 4. 
Forest, Arima, Trinidad (Britton, Britton and Brown 2403). 
In young flower March 18, 1921. 
The flowers are too young to enable the generic status of this 
tree to be certainly determined. Mr. N. E. Brown has identified 
specimens as the same as Crueger’s mo. 247 in the Kew Herbarium, 
from Trinidad, which is a leafy branch and a detached fruit. 
The leaves are also the same as those of Trinidad Herbarium 
no. 1454, also leafy shoots with the remains of a fruit which was, 
apparently, about 2 cm. long, attached, and with some flowers 
even younger than those of our 2403. “ 
Evolvulus bocasanus sp. nov. 
Perennial, shrubby, branched, 3-4 dm. high, the branches 
nearly erect or ascending, strigose. Leaves lanceolate to. oblong, 
2~5 cm. long, 5-15 mm. wide, strigose on both sides, acute or 
obtuse at apex, obtuse at base, pinnately few-veined, the veins 
nearly parallel, the petiole 1-2 mm. long; peduncles filiform, 
axillary, 3 cm. long or less, 1-few-flowered; bracts lanceolate, 
acuminate, 2-3 mm. long; pedicels 2-10 mm. long; calyx strigose, 
3-4 mm. long, 5-lobed to about the middle, the lobes lanceolate, 
acute: corolla rotate, bright blue, 8-15 mm. broad. 
Hillsides, Bocas Islands, Trinidad; type from Chacachacare 
(Britton, Freeman and Watts 2674). In flower April 3, 1921. 
This is the species recorded from Trinidad by Grisebach as Evol- 
vulus alsinoides L., at least in part.
