cells. If the published character of Trichostema^ and of the order were perfectly correct, it 

 would also differ importantly in the amphitropous descending ovule. But in Trichostema, also^ 

 the ovules are amphitropous or between that and anatropous. The seed, however, is attached 

 below the middle, whereas in Tetraclea it is attached above the middle ; but this is merely a 

 difference of degree. The anthers are not drawn quite right in the plate. They are scarcely 

 emarginate at the upper^ but deeply lobed at the lower end, and perfectly opposite or parallel*''

Plant 1-2 feet high, nearly simple or moderately branched. Leaves 1-1| inch long, and 

 3-5 lines wide ; 4-6-toothed on each margin ; scabrous on both sides, with short appressed 

 hairs, which commonly arise from an elevated base. Peduncles solitary in the axils, 2-6 

 nches long. Heads (exclusive of the corolla) about one-third of an inch in diameter ; the 

 flowers closely aggregated. Corolla funnel-form, with a short tube, half an inch long and of 

 equal diameter ; white or pale rose color ; the lobes short and slightly emarginate. Fruc- 

 tiferous calyx somewhat enlarged, the teeth triangular-ovate. Stamens included. Stjde long 

 and filiform ; the apex twice 2-cleft. Ovary 4-celled^ the ovules ascending. Drupe about the 



abis) 



endocarp reticulate-pitted. Cotyledons distinctly 



plicate longitudinally. Apparently allied to C. patens. An undescribed species of this genus 

 was found by Gregg in the Balson de Mapimi. It may be thus characterized : 



CoRDiA Greggii, (n, sj).): ramosissima, scabro-pubescens ; foliis obovatis obtusis dentatis 

 plicato-rugosis, basi longe cuneatis ; cymis contractis subcapitatis paucifloris ; laciniis calycis 

 setaceis tubo campanulato brevioribus ; corolla glabra infundibuliformi-campanulata. In the 

 northern part of the Balson de Mapimi, flowering in April. A shrub 5-8 feet high. Leaves 

 scarcely half an inch long, of a pale greenish gray color. Peduncles terminating the leafy 

 branches, an inch long. Cymes 8-12-flowered, the flowers at first in a dense head, but after- 

 wards unfolding a little. The upper part of the 5-6-toothed calyx clothed with short blackish 

 hairs. Corolla more than an inch in diameter, white j the lobes obtuse and entire. Stamens 

 5-6, scarcely half the length of the corolla. Ovary tapering to a long slender style. Ovules 

 ascending. This species connects the sections Dasycephal^e and Cordiopsis. It is allied to C. 

 parvifolia, but has a much more contracted inflorescence.
