Apocinece.] MEXICO.— SUPPLEMENT. 437 



petiolum dilatatum reductis, corymbis amplis paniculatis, pedicellis bracteatis bracteis 

 subulatis, capitulis multifloris, involucri campanulati squamis sub 10 oblongis acutis 

 striatis interioribus latioribus late scariosis. 



Hab. Between San Bias and Tepic. — A tall handsome plant with copious rather large flowers, but smaller 

 than in the preceding species. 



1. Cirsium cernuum. Lag De Cand. Prodr. 6. p. 639. 



Hab. Between San Bias and Tepic— The heads of flowers in our dried specimens are erect : but in 

 other respects the species quite agrees with the description of the plant to which we have referred it. 



1. Trixis frutescens. Browne, Jam. p. 33./. 1. De Cand. Prodr. t. 7. p. 68. 



Hab. Between San Bias and Tepic— Our Trixis latifolia (supra, p. 300) is the Acourtia formosa, Don, 

 and De Cand. Prod. 7. p. 66. and is also in the present collection. The genus Acourtia, however, scarcely 

 seems to differ from Trixis. 



Ord. XXVII. LOBELIACEiE. Juss. 



1. Lobelia laxiflora (H.B.K.) ; caule erecto ramoso, foliis subsessilibus ovato-acumi- 

 natis serrato-dentatis, pedicellis axillaribus nudis vel medio bibracteolatis folio subaequa- 

 libus, tubo calycis hemisphserico, lobis lanceolatis acutis tubum longitudine sequantibus, 

 corolla intus pubescente 6° 8°ve brevioribus, antheris apice hirsutis, capsula semisupera.

 H.B.K. {fide De Cand.) Siphocampylus bicolor. Don. Brit. Fl. Gard. t. 389. 



Hab. Realejo A very variable species, with the habit of Tupa or Siphocampylus, to which latter 



genus Don refers it without hesitation. In our present specimens the leaves are crowded, broadly lanceolate, 

 acuminate, wrinkled, more or less downy, especially the upper ones. The flowers do not extend much be- 

 yond the length of the leaves. Our L. lanceolata and angulato-dentata (supra, p. 301.) and L. ovalifolia 

 (supra, p. 299), belong to the same group with the present, and may possibly be forms of the same species : but 

 if so it is the most variable with which we are acquainted. 



Ord. XXVIII. ERICEiE. Juss. 

 1. Gaultheria odorata. H.B.K.— fi. Mexicana. De Cand. Prodr. 7. p. 595. 



Hab. /3. Realejo. — The pedicels are scarcely so long as De Candolle describes them to be in this variety ; 

 but the plant is quite the same as Andrieux's PI. Mex. n. 264, to which De Candolle refers. 



Ord. XXIX. APOCINEJE. Br. 



1. Vinca rosea. L. 

 Hab. Between San Bias and Tepic. No doubt an introduced plant.
