1. Ammannia catholica. var. Schlecht. in Linnaa, 5. p. 568. 



The specimen is unique, and very much advanced, so that we have not seen the petals, nor do we know 

 how, in this state, it may be distinguished from A. occidentalis, De Cand., which may therefore prove the 

 same species. 



2. A. sanguinolenta. Sw.—De Cand. Prod. 3. p. 80. Schlecht. in Linnma, 5. p. 568. 

 The petals, in a dry state, are not of a blood-colour, but very pale pink. 



1. Cuphea bracteata; fruticulosa patens, ramulis calycibusque patentim hirto-pubes- 

 centibus, foliis ovato-lanceolatis acuminatis basi subcordatis subsessilibus utrinque hirto- 

 pubescentibus, pedicellis unifloris solitary's vel binis supra axillaribus alternis folio floral i 

 2-4-plo brevioribus, caiycibus 6-7 lin. longis basi gibbis, petalis 6 duobus obovato-oblongis 

 (3-4 lineas longis) casteris pusillis cito marcescentibus, staminibus 12? inclusis alternis 

 pilosis, ovario sub 14-ovulato styloque glaberrimis. — C. bracteata. Lag. ? 



Hab. Talisco. — The longer and unguiculate petals are purple, the others (when dry) pale. It appears to 

 belong to De Candolle's section " Fruticosm." 



2. C. tenella; annua ramosa, ramis gracilibus puberulis, foliis angusto-lanceolatis obtuse 

 acuminatis basi in petiolum attenuatis utrinque glabris vel minute puberulis, pedicellis 

 capillaribus oppositis (nunc alternis) folium florale asquantibus, calyce fructifero anguste 

 oblongo basi subaequali glabro glanduloso punctato, petalis minutis, stylo brevi pubes- 

 centi, fructu 21-24 spermo. 



Calyces floriferi vix lineam superantes, subcylindracei ; fructiferi 1-sesquilineam longi, anguste ampullacei, 

 collo oreque obliquis. 



We have not ascertained satisfactorily the number of stamens, although there are at least eleven, and we 

 think twelve ; they are all included within the tube of the calyx ; the number of petals is also doubtful, but 

 appears to be six. 



3. C. floribunda ; caule fruticoso ramoso, ramis elongatis scabris, foliis oblongo-lanceo- 

 latis acuminatis basi in petiolum longiusculum attenuatis utrinque nitidulis scabris, 

 floribus racemosis in paniculas secundas saepius digestis, ramis inflorescentia? bracteisque 

 linearibus patentim glanduloso-hirsutis, calycibus deflexis arcuatis basi obtuse calcaratis 

 pubescenti-viscosis ore intus villosis, ovario 18-21-ovulato apice in stylum exsertum 

 glabrum sensim attenuato. 



Hab. Talisco and Tepic— The calyx is red, and resembles that of C. Melvilla:, but is not above eight or 

 nine lines long. The two tolerably large petals (l£-2 lines long) are of a deep blood-red colour, the others 

 we have not observed. There seem to be eleven stamens, all of them included. It obviously approaches to 

 C. secundiflora, Fl. Mex., which we at one time thought it might be ; but that is said to be an annual, or 

 at all events an herbaceous plant. It is also much allied to C. Melvillai, but that has longer calyces and no 

 petals. 



4. C. barbigera ; caule fruticoso ? scabro, foliis subsessilibus utrinque hispidis oblongis 

 basi obtusis apice acutiusculis, pedicellis brevibusextra-axillaribus terminalibus racemoso- 

 spicatis subsecundis, calycibus longe tubulosis basi obtuse calcaratis hirsutis, petalis
