Asuncion (3U, 804 and 829 a). Elower October; fruit January. 



A handsome tree with smooth lightish-gray bark, from 10 to 13 

 m. in height. It has a head of drooping limbs, and light, 

 graceful foliage. Leaves bipinnate, with 10-25 pairs of pinnae; 

 each pinna with 50 or more pairs of light green, minute, oblong 

 leaflets. The main rachis is channelled above, and one-third of the 

 way up the petiole there is a small, oblong, flat red gland which 

 looks like an insect resting upon it. Flowers light yellow, in 

 globular heads, axillary, in pairs. Fruit a large, flat pod, 4-17 cm. 

 long, 2-3J cm. wide, with raised borders on each valve, dehiscing 

 on the lower side ; the upper side, and sometimes the lower, wavy 

 or irregularly and deeply notched, imparting a jointed look to it. 

 The pod contains from 6 to 12 flat, dark brown, smooth seeds. 

 This tree grows in sandy, open grounds. The native name was 

 given to me variously, now as Yarupi, and now as Cypay, the y 

 sounding something like the French u. 



PJptadenia commuiliSj Benth. in Mart. Fl. Bras., XV, pt. 2, 279. 



Asuncion (756). Young fruit, June 20. 



A tree similar to no. 371 in general appearance, in foliage, and 

 fruit, but handsomer in shape, the bark whitish, very smooth, and 

 the limbs rising upward and bending over in a graceful curve. The 

 petiolar gland is small, oval, and cup-shaped. It attains a height 

 of from 16 to 20 m., and forms a beautiful object in the monte 

 around Asuncion. The leaves have only 6-9 pairs of pinnae, the 

 ultimate segments a little larger than those of no. 371, somewhat 

 falcate in shape. The native name, as I understood it, is Yerayu.
