380 PROCEEDINGS OP THE AMERICAN ACADEMY 



— In canons of the mountains near Jinaulco, S. W. Coahuila. " A 

 spreading shrub or low-bianched small tree, with creamy-white and 

 fragrant flowers." Pringle, 142. 



Genipa ECHiNOCARPA. Randia ecJiinocarpa, DC. Prodr. iv. 385, 

 and in Mo9ino & Sesse, Ic. ined. t. 469. " Called Pajmche. Shrub 

 or small tree, 6 to 10 feet high, with sharp thorns ; its numerous fruit 

 covered with fleshy protuberances, of a dark green color outside ; 

 when ripe the inside is black, is much eaten, ripens in winter." — At 

 the hacienda San Miguel, near Batopilas, Palmer, A. The dried 

 fruit sent is firm-corticate, 2 inches in diameter, resembles the pub- 

 lished tracing, except that a good number of the fleshy tubercles have 

 developed into soft spines of nearly half an inch in length. The 

 seeds, imbedded in the pulp, are not well preserved, but are flat and 

 orbicular, and seem to be those of a Genipa ; and there is no dis- 

 sepiment. The spines of the branches are those of a Randia. Dr. 

 Palmer sent no flowers. But I judge from the foliage that the flow- 

 ering specimens of Ervendberg's collection at the settlement of War- 

 tenberg, near Tantoyuca, distributed as " no. 239, Randia," may be 

 the same ; that has a one-celled ovary, and subulate calyx-lobes. 



MACHAONIA, Humb. & Bonpl. § Platyanthea. Corolla tubo 

 vix ullo fauce concava fere rotata. Spec. 2 : — 



Machaonia fasciculata, Gray, Proc. Am. Acad. xix. 77. Mi- 

 crophylla ; foliis in axillis fasciculatis parvis subspathulatis. — Mexico, 

 Coulter, no. 1167. 



Machaonia Pringlei. Inermis : foliis (hand fasciculatis) lanceo- 

 latis utrinque acutis vel acuminatis subpetiolatis fere eveniis glaberri- 

 mis (1-2-pollicaribus) ; cymis laxe floribundis ; floribus 4-5-meris ; 

 corollas (albge) lobis margine tenuiter undulatis. — S. W. Coahuila, 

 on limestone ledges of the mountains near Jimulco, April, in flower : 

 " a shrub 3 to 6 feet high," Pringle, 146. The funiculus from the 

 summit of the cell is attached to the oblong-linear ovule about half- 

 way between its middle and the micropyle. 



Mitracarpus villosus, Cham. & Schlecht. in Linn. iii. 363 (name 

 by implication), & DC. Prodr. iv. 572 (fairly similar to the W. Indian 

 plant) ; Hemsl. Biol. Centr.-Am. Bot. ii. 61. Near Batopilas, Palmer, 

 38. Includes the plant of Berlandier which has been referred to M. 

 hrevijlorum. Differs from that in pubescence, though not enough to 

 merit the specific name, in more evident venation, and in bearing 

 bristly hairs along the margins of the sepals, but not so strikingly as 

 in Jacquin's figure. For the reason of a return to the original or- 

 thography of the generic name, see Syn. Fl. N. Am. ii. 32.
