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., /S.* demissa : humilis ; racemo laxo breviter 

 pedunculato ; pedicellis floriferis patentibus fructiferis recurvis ; legumine parum 

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



■ Near Saltillo and Parras, Northem Mexico, Gre^^ ( 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 racemcs, lead me to refer it to H. stricta, Benth. My Coulterian 

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

 Wrighfs and Gregg's plants are miuutely glandular, and often falcate, though more 

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

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

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

ection of 1851 well accord, except that the flowers are perhaps rather krger and 



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



over a foot h.gh. - Mr. Bentham contributes the following remarks. " The above 



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



portant characters The stipules are broadly ovate, membrauaceous, blunt 



scarcely pomted ; the petioles long and slender. with usually 3 or 4, somctimes 5 or
