diameter. The two angles formed by the juncture of the convex and 

 flat surfaces of the seed are outlined by a narrow line of dense, short, 

 glossy black hairs on one and two such lines on the other angle; on 

 the lower lateral sides of the concave surface are small rather closely 

 set patches of like hairs. The reason for the presence of two lines 

 of hairs on one angle and one on the other may be explained by the fact, 

 that had all four ovules developed then each seed would have had the 

 shape of a longitudinal one-fourth section of an ovoid — i. e., with two 

 flat faces and one convex one, and on each of the three angles would 

 be a line of these short hairs. Since in our specimens there was but 

 one seed in each cell, these each occupied the entire space of the cell 

 and took on a half-ovoid shape, bringing two angle-lines of hairs close 

 together.— Plate VII. 



The original plant (No. 232/07/1) is growing at the 

 Missouri Botanical Garden as are also several cutting 

 propagations from it. Herbarium material was made 

 from the original plant and specimens deposited in the 

 herbaria of the Missouri Botanical Garden and of Pro- 

 fessor H. D. House, Biltmore, N. C. 



Thkee New Crassulaceae. 



The Missouri Botanical Garden now possesses a very 

 good living representation of the Crassulaceae. Many 

 of the specimens have been derived directly from the 

 Mexican field, and, since the appearance of the mono- 

 graph of the order, by Britton and Rose,^ it is quite evi- 

 dent some of these species are nondescripts. In present- 

 ing the following species the classification and form of 

 description used in the above cited monograph have been 

 followed as nearly as possible. 



Eclieveria finibriata n. sp. 



Caulescent, stem 4.5 dm. to the rosette, 2 cm. in diameter. Rosette 

 open, comparatively few leaves; leaves oblanceolate, 12 cm. long, 6.2 

 cm. wide, — 3.5 cm. from the rounded obtuse apex, tapering to a very 

 thick base. 2 cm. wide by 1 cm. thick, valiculate concave in the 

 expanded blade portion, groove-channeled down the upper face of the 

 basal portion, where the margin is thin, narrow, and sharp wing-like, 

 and the under surface convex with a prominent obtuse keel, which ends 

 in a decurrent obtuse spur below the transversely oblong attachment.
