Brittox: Studies of West Indian plants 337 



Forest near the summit of Mount Tocuche, Trinidad (Britton, 

 Hazen and Mendelson 124J). 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. 



Chrysoprryllum (?) minutiflorum sp. no v. 



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, 192 1. 



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 no. 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 26/4). In flower April 3, 1921. 

 This is the species recorded from Trinidad by Grisebach as Evol- 

 vulus alsinoides L., at least in part.
