We have here added a specific character, M. de Jussieu having mentioned three other species from the 

 Mauritius. The present one was long involved in the greatest obscurity, on account of the synonyms asso- 

 ciated with it by Burmann. There does not appear to be any plant described by Roxburgh or Willdenow to 

 which it is referable : in habit it approaches to Croton oblongifolium, Roxb. Fl. Ind. 3. p. 85. 



1. Acalypha Indica. Linn. — Roxb. Fl. Ind. 3. p. 675. 



2. Acalypha Chinensis ; caulibus pubescentibus herbaceis, foliis sublonge petiolatis rhom- 

 beo-ovatis crenatis, spicis androgynis axillaribus petiolum a?quantibus vel superantibus, 

 florum foemineorum fasciculis solitariis binisve bracteatis, masculis terminalibus in spicam 

 pedicellatam capitatam vel longiusculam dispositis, bracteis foemineis cordatis acuminatis 

 crenatis, fructu hispido. A. Chinensis. Roxb. Fl. Ind. 3. p. 677 ? 



Roxburgh ascribes to his plant, so far as we can collect from the description, a single cluster of female flowers 

 and a small capitulum of male ones from a solitary bractca : some of the spikes on the specimens before us 

 agree with that character, but others show two bracteas, and in one, where the inflorescence is almost ter- 

 minal, the male flowers form a slender spike of about half an inch in length. 



3. Acalypha hispida. Willd. — Urtica pilosa. Four. Fl. Coch. 2. p. 682. Roxb. FL Ind. 3. 

 p. 676 (non Cav. nec Willd.) — (3. pubescens. A. flexuosa. Herb. Wight, olim. 



We have only received var. /3 from Canton. It is merely distinguished from the type of the species by 

 its stems not being hispid with spreading hairs, but simply pubescent. We possess both from the Peninsula 

 of India.

Involucri glandules 4, pallida;, orbiculares, disciformes, processubus concoloribus suif'ulcientibus minutis inter 

 se subsequalibus duplo minores : fructus parce strigosi, parvi : semina ecarunculata, brunnea, obtuse tetra- 

 gona, transverse subundulata. — The flowers occur several together in the axils, but they are very shortly 

 peduncled, often almost sessile. This, with the following, belongs to Dr. Roepers first section, characterised 

 by the seeds destitute of a carunculus, and the glands of the involucre resting on one side of a more 

 or less membranaceous scale or process, which he properly suggests ought to be regarded as analogous to 

 stipules, they only occurring in the species provided with stipules.

Involucri glandules minute, sanguineae, orbiculares, processubus ejusdem fere coloris ac substantia; et vix

 caruncula arillari destituta. — It is n. 100, a, b, c, of Mr. Vachell's collection. 



3. Euphorbia Vachellii ; annua, erecta, glabra, glauca, foliis oppositis brevissime petiolatis, 

 linearibus acutis argute serrulatis, inflorescentia axillari fasciculata laxiuscula, involucri
