small in comparison, glabrous, and only minutely or scarcely at all ciliated along the angles of inflexion, com- 

 monly called the margins. We have not seen the stem or leaves, nor can we refer it satisfactorily to any 

 described species : in many points it approaches to B. Blumeana, Schult. Syst. Veg. 7. p. 1343, but that 

 species is said to have the spikes or branches of the panicle solitary, and the spikelets surrounding the knot 

 on all sides : the other parts of Schultes' description agree pretty well, so that, perhaps, our plant ought to 

 be considered a variety of B. Blumeana.}

3. L. canaliculatum. L. — Hook, el Grev. in Bot. Misc. v. 2. p. 386. — (3. pallidius ; minus 

 nitidum, ramis magis attenuatis, caule inferne stolonifero. 



Hab. Macao ; Vachell. — The Lycopodia with sessile spikes, distichous leaves, and superior stipules 

 arranged in two series, so abundant in the tropics, are by no means easy to define. The present, in its paler 

 colour, less glossy foliage, and more attenuated branches, differs from what we conceive to be the true L. 

 canaliculatum ; but we can hardly consider these characters sufficient to separate it from that species. 



1. Osrnunda Vachellii ; fronde pinnata basi fructificante, pinnis lineari-lanceolatis 

 coriaceis integerrimis. Hook. Ic. Plant, t. 15. 



Hab. Macao and neighbouring islands ; Rev. G. H. Vachell. — An extremely singular and beautiful 

 species of Osrnunda, resembling, however, the O. Javanica of Blume ; but that has many of the pinnae lobed 

 and pinnatifid, and the fructification confined to the middle pinnse. 



1. Mertensia Hermanni Gleichenia Hermanni. Br Hook, et Grev. Ic. Fil. t. 14. 



— Mertensia dichotoma. Siv. — Polypodium dichotomum. Th. Fl. Jap. t. 37. 



Hab. Macao; Vachell; Millett. 



2. M. glaucescens. Willd. 



Our specimens exactly agree with one from Brazil, sent under this name by our friend Dr. Klotzsch, 

 and which has doubtless been compared with the original plant in Willdenow's herbarium. The pinna are 

 very glaucous beneath, but narrower than in the last species, always downy or rather arachnoideo-tomentose 

 beneath, especially on the ribs. 



1. Lygodium Japonicum. Sio. 



Hab. Macao and Lappas Island ; Vachell.— This varies much in the length and breadth both of the sterile 

 and fertile pinnules.
