162 Plants Collected in Paraguay. 



the lobes erect, linear, acute, pubescent, not quite as long as the tube of the 

 corolla, 1 or 2 glandular in each axil. Corolla about 7 mm. high, greenish, 

 pubescent, the lobes ovate-lanceolate, pubescent at the junction with the 

 stamineal crown inside, at length reflexed. Segments of the crown connate 

 with the throat and the gynostegium, light purple on the back and almost 

 violet-tinted on the face, J as long as the corolla lobes. Caudicle not dilated, 

 the teeth erect and very short. Apex of the stigma entire, longer than the 

 corolla lobes. Fruit not seen. 



A half shrubby plant, 4-6 dm. high, with milky juice, growing- 

 in waste grounds at Asuncion (110). November. 



Ootliofreda eriantlia (Dcsne.), Kuntze, Rev. Gen. PL, 420. 

 Orypetalum erianthum, Dcsne., D.C., Prod., viii, 584. 



Asuncion (655). April. = Balansa 1335. 



Clambering over low bushes in thickets, and producing a great 

 number of intertwisting branches. Flowers small, white, fragrant, 

 in axillary clusters. Tube of corolla short, lobes long, linear, 

 spreading. Stigma produced into 2 long, strap-shaped appendages. 

 Stem, leaves, pedicels, calyx, and corolla all densely villous or 

 woolly. Fruit a large conical, smoothish follicle. This plant, like 

 many other Asclepiadaceous species, is an insect-catcher. On one 

 occasion I found a large moth completely imprisoned by a flower, 

 and struggling desperately to get loose, but in vain. It had thrust 

 its proboscis into the corolla in search of nectar and was unable to 

 withdraw it, although a powerful insect — in fact, as large as one of 

 the smaller humming-birds, and for that reason called the humming- 

 bird moth. 



Ootliofreda gracilis, Morong, n. sp. 



A slender vine climbing over bushes and shrubs. All the parts except the 

 petals grayish tomentose. Leaves opposite, cordate, acuminate, H-4 cm. 

 long, 6 mm, to 2 cm. wide, on petioles 3-15 mm. long. Flowers greenish- 

 white, axillary, in 2s, on peduncles 5 or 6 mm. long; pedicels 8-15 mm. long. 

 Sepals 5, green, erect, subulate, with 1 or more glands in each axil, about 4 

 mm. long ; corolla so deeply lobed as to appear of 5 separate petals, the lobes 

 erect, oblong, obtuse at the apex, 10 or 12 mm. long, 2-3 mm. in breadth, 

 glabrous on both sides. Scales of the crown barely adnate at the base with 

 tlie corolla lobes, 5 or 6 mm. long, bifid lialf-way up, the divisions beautifully 

 fringed. Caudicles scarcely dilated, slightly gibbous ; the gland oval, very 

 short. Gynostegium truncate, with 5 bluntish lobes at the top. This vine is 

 much branched, twining densely upon itself. Fruit not seen.
