inserts, filiforniia, inter se spiraliter contorta: antherm sagittate acuminate medio stigmati coherentes. 

 Glandules hypogynae 5, majusculae, carnosae, glabrae. Germen ovatum, compressum, hiloculare. Stylus 

 mucus, filiformis. Stigma e basi dilatata conicum. 



This, if it be a Parsonsia, belongs to the second section, which hitherto consists of Australasian species: 

 but we think there are sufficient characters, although we are ignorant of the fruit, to constitute it a distinct 

 <*enus: in which case the plant may be named Helicandra Sinensis. 



1. Holarrhaena affinis ; antheris oblongis medio tubi insertis, stylo subelongato. 



Corolla hypocrateriformis, fauce tuboque intus pubescenti absque squamis denticulisve. Stamina inelusa: 

 Jilamenta nulla: antherm medio tubi inserte, a stigmate libera, oblongae, integrae, longitudinaliter pollini- 

 ferae. Annulus subcarnosus, tenuis, brevis, pistilli basin arete cingens, alioquin squamae nullae hypogynee. 

 Germina duo. Stylus subelongatus, tubo subdimidio brevior. Stigma cylindraceo-capitatum. 



This accords so well with the figure in Vahl, Symb. 3. t. 59, of H. mitis, Br., that we should have con- 

 sidered it identical, did not Brown and Vahl describe the stamina as situated at the bottom of the tube 

 of the corolla, as having almost no style, and omit all mention of the little annulus that surrounds the base 

 of the germen. 



ECDYSANTHERA. (Hook, et Am.) 

 Calyx 5-partitus, laciniis lanceolatis. Corolla subcampanulata ; limbo 5-fido, paten te, 

 laciniis aequilateris, per aestivationem contortis ; fauce tuboque intus absque squamis denti- 

 culisve. Stamina medio tubo inserta: Jilamenta brevissima: antherm semiexsertae, sagittatse, 

 medio stigmati cohserentes, lobis posticis polline vacuis. Annulus hypogynus, brevis, tenuis, 

 pistilli basin cingens. Germina duo. Stylus unicus, brevis. Stigma conico-capitatum, 

 acutum. — Frutex erectus ? Folia sublonge petiolata, elliptica, basi acuta apice subiter breve 

 attenuata, glabra. Panicula axillaris, elongata, laxe cymosa. Flores parvi, rosei. Corollse

Hab. Canton, Macao, and the adjacent islands. Messrs. Lay and Collie, Mr. Millett, and Mev. G. H. 

 Vachell. (No. 144.) 



There can be no doubt, we believe, of this being a genus distinct from any previously described. It is 

 extremely allied to the next in habit; and it is probable that Echites ? lucida, Wall. List, n. 1670, belongs 

 one or the other, but we have not seen flowers sufficiently advanced for examination.

POTTSIA. (Hook, et Am.) 

 Corolla hypocrateriformis, fauce tuboque esquamatis, limbo 5-partito, patente, laciniis 

 aequilateris, per aestivationem haud contortis. Stamina exserta: Jilamenta fauce inserta, 

 usque ad medium tubi decurrentia ibique intus dense pubescentia, apice glabra, simplicia : 

 antherm sinu lato sagittatae, medio stigmati cohserentes cupulamque obtusam supra illud 

 formantes: lobis posticis subulatis incurvis polline vacuis. Germina duo, villosa: Stylus
