ing to olivo, with tlie calyx generally red on one side. Whole plant 

 neai'ly glabrous, except the upper part of the stem and the 

 peduncles, which are clothed with gland-tipped hairs. 



The habit of this species is totally distinct from that of A. verna ; 

 in its mode of growth it is more like a Sagina, and there appears 

 to be no complete chain of intermediate forms between it and 

 A. verna, although the characters which separate the two may 

 appear on paper to be unimportant.

Eoot annual, without barren shoots. Stems erect or ascend- 

 ing, paniculately branched (especially at the base); the branches 

 ascending or spreading. Leaves distant (except at the very base 

 of the stem), linear-subulate, mucronate, 3- to 5-nervcd, the nerves 

 conspicuous only towards the base. Flowers numerous, in lax 

 dichotomous cymes terminating the stem and branches. Pedicels 

 two to four times the length of the sepals, and considerably longer 

 than the bracts when mature. Sepals lanceolate-acuminate, ter- 

 minating in subulate points, strongly 3-nerved. Petals oblanceolate- 

 oblong, from one-half to two-thirds the length of the sepals. 

 Capsule about equal in length to the sepals, or a little exceeding 

 them. Seeds roundish-reniform, slightly rugose on the disk, sur- 

 rounded by a marginal band of small tubercles.
