 — These plants have stems like those of Epiphyllum hut hear rather small deep purple flowers 

 which appear at the liases of (he erenat ions. This species is a native of Panama; W. Ama- 

 zonica is a Peruvian species and is the generic type. A third species, IV. Coxtaricensis, is

2290. Skan, S. A. Ipomoea dasysperma. Curtis Bot. Mag. 15: PI. 8788 (colored). 1919. 

 — Peculiar to the genus in having yellow flowers and saccate outer sepals. An attractive 

 garden plant native in Tropical Asia and Africa. Has had many names, including, probably 

 I. saccata Hallier f. — Oliver A. Farivell. 



2291. Skan, S. A. Ipomoea Pes— tigridis var. longibracteata. Curtis Bot. Mag. 15: PL 

 8806 (colored) . 1919. — This variety comes from East Tropical Africa and is a climbing annual, 

 reaching 6 feet or more. The flowers are white with the tube purplish without and violet 

 within. It belongs to the section Cephalanthae characterized by the rather small flowers 

 being arranged in dense bracteate heads. The typical species has a wide range extending 

 from East Tropical Africa through southern Asia to China and the adjacent coastal Islands. 

 It prefers a sandy soil. — Oliver A. Far well.

2294. Staff, Otto. Protea longifolia. Curtis Bot. Mag. 15: PI. 899S (colored). 1919 — 

 A species of southern Africa that has had a cultural history approaching two centuries and 

 as might be imagined has been described under a number of different names now reduced to 

 syonymy. Three species, still kept distinct, P. ignota, P. ligulaefolia and P. vmbonalis 

 were based upon plants raised from seed at Schonbrunn. These are kept distinct from P. 

 longifolia on the shape of the centre of the flowering head, length of the perianth-arms, and 

 the coloring of the involucral bracts. Andrews considered them as but forms of P. longifolia 

 and it is suggested that the differences are such as may be expected under the favorable 

 conditions of our climate, the heads not developing perfectly and normally. — Oliver A. 

 Farwell. 



2295. Turrill, W. B. Lonicera similis, var. Delavayi. Curtis Bot. Mag. 15: PI. 8800 

 (colored). 1919.— This is a climbing, yellow flowered shrub of western China. It is a hardy 

 evergreen, flowering as late as August. It thrives well in a loamy soil and can be increased 

 by late summer cuttings.— Oliver A. Farwell.
