3, nearly sessile: capsule ellipsoidal, each of its 3 valves 2-toothed, 

 shorter than the calyx; seeds several. 



Some of its characters are suggestive of S. umbellata Turcz. (Alsine bat- 

 calensis Coville) . That also is apetalous and has five stamens, but in it they 

 alternate with the sepals. The capsule is oblong-ovoid and twice as long as the 

 sepals. The seeds in the two seem nearly identical, with an almost annular 

 embryo. The aspect of the two species of course is wholly different, S. prae- 

 cox looking more like a very slender S. longipes Goldie. 



The plant has added interest because many of the scarcely distorted cap- 

 sules were found to be filled with a smut which Dr. Clinton pronounces as 

 new also, and to which he has given the name Ustilago Stellariae. 



Macbride secured this at Falk's Store, Canyon County, Idaho, on moist 

 slopes, under sagebrush, no. 763, April 24, 1911. 



Crataegus tennowana, n. sp. — Small treelike shrubs, 3-6 m. 

 high, sometimes growing in clumps and then lower and less tree- 

 like: trunk short, usually less than 1 dm. in diameter: spines 

 straight, nearly at right angles, lustrous reddish-brown becoming 

 grayish, about 15 mm. long (1-2 cm.): leaves mostly oval (varying 

 to suborbicular) in general outline, both base and apex with rounded 

 contour, often however cuneately narrowed below and more 

 rarely above as well; the upper half from shallowly to deeply and 

 irregularly serrate, the teeth with more or fewer gland-tipped ser- 

 rulations; the lower half glandular serrulate or with a few sessile 

 glands on the entire margins (occasionally the glands extend down 

 upon the petiole which is only 2-10 mm. long) ; pubescence want- 

 ing from the first upon the petioles and on the underside of the 

 leaves, sparsely and minutely hirsute on the upper side, especially 

 along the veins, from the first to maturity; the veins of the rather 

 thin leaves somewhat superficial on the lower side, the midrib 

 flattened and narrowly wing-margined, at least in the young 

 leaves: corymb wholly glabrous except for a slight pubescence 

 on the inner face of the calyx lobes, 5-15-flowered, with scattering 

 glands on the peduncle and pedicels and very rarely on the tri- 

 angular-lanceolate persistent calyx lobes: stamens seemingly 8 

 when the styles and carpels are 4, and 10 when the styles and
