56 PLANTiE WRIGHTIANiE. V. 



ered ones, distributed under this number, belong to the next species, from which I 

 am not sure if H. densiflora is sufficiently distinct. 



148 (partim). H. stricta, Benth., 13. demissa: humilis ; racemo laxo breviter 

 pedunculate ; pedicellis floriferis patentibus fructiferis recurvis ; legumine parum 

 falcato, — Mountain valleys west of the pass of the Limpia ; Aug. Also in the 

 collection of 1851. Near Saltillo and Parras, Northern Mexico, Gregg (No. 268, 

 &c.). — Mr. Bentham has distinguished this, under the name of H. demissa: but 

 the copious flowering specimens since gathered by Mr. Wright, some of them 

 dwarf, with the raceme much longer than the rest of the plant, others nearly a foot 

 high, with stricter racemes, lead me to refer it to H. stricta, Benth. My Coulterian 

 specimen is destitute of fruit, indeed; but the very obtuse legumes both of 

 Wright's and Gregg's plants are minutely glandular, and often falcate, though more 

 commonly straightish. They are from an inch to an inch and a half long, scarcely 

 3 lines wide, 6 - 12-seeded (ovules about 12). The stems and pedicels are more 

 or less stipitate-glandular, as well as the calyx. 



$■ " H. STRICTA (sp. nov.) : stipulis late ovatis ; ramis parce glandulosis foliisque 

 puberulis glabratisve; pinnis 4-6-jugis cum imparl; racemo stricto; pedicellis dis- 

 sitis suberectis calycibusque pubescentibus et stipitato-glandulosis ; vexillo dense 

 stipitato-glanduloso ungue dilatato ; legumine falcato glanduloso polyspermo." 

 Benth. Mss. — Zacatecas, Mexico, Coulter. With this, specimens in Wright's col- 

 lection of 1851 well accord, except that the flowers are perhaps rather larger and 

 the pedicels more spreading. They are not in fruit. The tallest specimens are 

 over a foot high. — Mr. Bentham contributes the following remarks. " The above 

 species (H. stricta, demissa, and densiflora) agree with H. falcaria in their most im- 

 portant characters. The stipules are broadly ovate, membranaceous, blunt or 

 scarcely pointed ; the petioles long and slender, with usually 3 or 4, sometimes 5 or 

 6 pairs of pinnse, each bearing from 6 to 10 pairs of obliquely oval-oblong blunt 

 and nerveless crowded leaflets, without any odd one : the common petiole, however, 

 is always terminated, in my specimens, by an odd pinna, usually rather longer than 

 the lateral ones. In all these species, the divisions of the calyx are linear-oblong, 

 rather blunt, equal, or the lower one rather shorter and broader, generally persist- 

 ent, but sometimes falling off before the fruit is ripe. The four lower and outer 

 petals are nearly equal, scarcely oblique, obovate, and narrowed into long claws, 

 which bear copious stipitate glands on their inwardly turned edges. The upper and 

 inner petal, or vexillum, is equal in length, but very differently shaped : it is con- 

 cave or folded, the lamina rather smaller than in the others, the claw expanded in 

 the middle, and the copious stipitate glands are on the back instead of the front, 

 covering the claw and the lower part of the lamina. Stamens straight, nearly 

 equal (the lower ones rather longer), the filaments more or less beset with rigid 

 hairs and stipitate glands (the latter sometimes wanting), the five inner always less 

 hairy than the five outer, and all ten antheriferous in all the flowers I have exam- 

 ined. Ovary glandular ; the style smooth, clubshaped at the apex, with a contract- 

 ed opening more or less ciliate ; but these cilia and the thickening of the apex ap- 

 pear to vary according to the age of the flower. The pod is flat, the margins slight-
