HOUSTOUn's central AMERICAN LEGUMINOS^. 233 



There are only two of Miller's species of which we are unable to 

 find specimens. These are Psoralea hirta and P. capitata. These 

 have not, so far as we are aware, been taken up by any subsequent 

 writer, probably because the same specific names were employed by 

 Linuteus. But the Linnean plants are South African, and P. capi- 

 tata was pubHshed subsequently to Miller's plant, which is not 

 (most likely for the reason above suggested) taken up in the Index 

 Keivensis. In all probability Miller's plants are species of Dalea, 

 but in the absence of specimens it is impossible to say with certainty. 



The following Central American Loguminosa, not included in 

 Miller's Dlctionanj,-&\:e in the Herbarium from Houstoun : — 



^■Escliynoniene amerlcana L. Vera Cruz. 



Casalpinia bijuga Swartz. Campeachy. 



CaUiandra eriopJujlla Benth. Vera Cruz. 



Caliiandra gracilis Klotzsch. Carthageua. 



CaUiandra tergemina Benth. Vera Cruz; also in Herb. Sloane, 

 292, 82. Linnaeus founded this species (as Mimosa tergemina) partly 

 on Houstoun's MSS., in which there is a fall description of the 

 plant — there is also a sketch among his drawings. 



Calupogonium cairuleuni Desv. Vera Cruz. 



Cassia patellar ia DC. Vera Cruz. 



Cassia Tagera L. Vera Cruz. 



Meibomia barbata 0. K. Vera Cruz.

Hedysarum trijioram L. Vera Cruz. 



Lonchocarpus rugosus Benth. Campeachy. 



Hlujnchosia phaseoloides DC. Vera Cruz ; also in Herb. Sloane, 

 292, 42.
