Diverging and intergrading forms are abundant in the genus. 

 Noticeably so is it with the arboreal species, A. canadensis. 

 Trees occur whose leaves are pubescent throughout the season. 

 Leafy forms occur whose fruit branches are remarkably leafy, the 

 fruit being entirely hidden. Birds make such onslaughts on the 

 ripe fruit that in order to get it in quantity and perfection it is 

 necessary to study it miles away from the inhabited sections, for 

 birds are rare in such localities.

Ribes chihuahuense sp. nov. — Branches smooth, gray. 

 Leaves ovate to suborbicular in outline, the blades 2-2.5 cm. long, 

 dull dark-green above, pale-green beneath, broadly cuneate to sub- 

 truncate at the base, 3-lobed, glabrous on both sides, papillose 

 above when young, sparingly ciliate on the margin, the lobes 

 few-toothed, acutish or obtuse, petioles as long as .the blades or 

 shorter, pubescent when young ; racemes 3— 5-flowered, a little 

 longer than the leaves, the axis densely pubescent ; flowers

 flowers.

Fasciatioxs in Drosera, Ibervillea, axd Cecropia. — The 

 fasciated specimen oi Drosera roinjidifolia pictured herewith was 

 found in the propagating houses of the New York Botanical 

 Garen in March, 1907. The flattening affected the stem, result- 

 ing in a fasciated rosette, with a growing line 1.4 cm. in length. 

 The literature of teratology seems to contain no instance of 

 fasciation in this genus, while the odd character of the plants 

 makes the appearance of anomalous individuals the object of 

 peculiar interest. 



Another fasciation of a curious and rare species is that of a 

 shoot of Ibervillea Sonorae. One of the vine-like branches which
