Hab. Between San Bias and Tepic. — St Hilaire has endeavoured to show an affinity between this plant 

 and the Onagrarim. But it is surely more nearly allied to Cucurbitacem and Loaseoe. Professor Lindley 

 places it in this latter Order without any mark of doubt, though it differs from it in the definite stamens and 

 solitary pendent seed. There is an excellent figure of the entire plant in Jacquin's " Icones Plantarum 



Rariores" above quoted The flowers and fruit are nowhere accurately figured. The calyx is coloured, 



large, funnel-shaped, pubescenti-scabrous, divided half-way down into five broadly lanceolate erecto-patent 

 acute segments; at the base (which is incorporated with the ovary) are five, projecting, obtuse, decurrent teeth, 

 alternating with the segments of the calyx ; these teeth may perhaps be considered coadunate bracteas. At first 

 sight they may readily be mistaken for the calyx, and the real calyx for a corolla, and it is no doubt the pre- 

 sence of these which gave rise to the remark in De Candolle's Prodromus, quoted from Fl. Mexic. ins. ; 

 " Fructus junior costatus." On laying open the proper calyx, five linear-spathulate petals are seen, alternat- 

 ing with the lobes of the calyx, and shorter than those lobes, situated at the mouth of the tube. Stamens 5, 

 alternating with the petals, and inserted on the same line with them. Filaments as long as the petals, hair3 r . 

 Anthers oblong, 2-celled, opening anteriorly by two fissures. Ovary adherent to the base of the calyx, 1- 

 celled, ]-ovuled. Style filiform, rather longer than the stamens, glabrous: Stigma capitate, small. Fruit a 

 small indehiscent(?) capsule, crowned by the withered remains of the flower, 1-celled, with one pendent seed 

 occupying the entire cavity of the cell, globose. Albumen none. Embryo globose, of two hemispherical 

 cotyledons. Radicle superior, tuberculiform.

Hab. Realejo. — T. cuneiformis is described only as an inhabitant of Brazil. Our specimens precisely 

 accord with an unnamed Brazilian species in our Herbarium, gathered at Bahia by Saltzmann ; and also with 

 cultivated specimens from the garden of Gottingen under the name of T. cuneiformis.
