42 ON TWO NEW SPECIES OF CLEEODENDRON. 



Bentliam and Hooker in Genera Plantarum that I can add nothing 

 to wliat is there stated. Tliey estimate the number of species at 

 twelve, but only five of these have been published under the genus, 

 and so only five are enumerated in Index Kewensis. 



In Flora Brasiliensis Peterssen describes nine species of Ctenanthe 

 and twelve of Saranthe. In addition to these, at least three others 

 are in cultivation, and several others in English herbaria, gathered 

 by Gardner and Burchell, which Peterssen does not include. 

 IchnosipJwn Marian Eggers {Bot. Centralblatt, liii. 307, t. 2) is also 

 a Mijrosma, so that the number of species of the genus now known 

 is not less than thirty. 



ON TWO NEW SPECIES OF CLEEODENDRON. 

 By H. N. Ridley, M.A., F.L.S. 



In the Pianti Ospitatrici,* Prof. Beccari described a remarkable 

 Clerodendron, C. jlstuLosum, allied to C Siphonanthus, with fistulous 

 stems containing ants' nests. I have to add two more species of 

 this curious group, with the same habit, but with different in- 

 florescence and flowers. 



C. myrmecophila, n. sp. Sufirutex parce ramosa, glabra, 

 8-pedalis, cauli |- poUicis crasso, internodiis dilatatis, fistuloso, 

 cortice albo. Folia opposita vel alterna, herbacea, oblonga lanceo- 

 lata, pedalia, 4 pollices lata, acuminata, nervis 12 paribus, basi 

 obtusa vel acuminata, petiolo 3-pollicari, fistuloso. Panicula termi- 

 nalis pubescens ramis ultra-pedalibus. Bracteae lineares, |-pollicares, 

 persistentes, ad apicem comoste. Flores in apicibus ramorum 

 paniculae congests, aurantiac^. Calycis sepala 5 linearia acuta 

 pubescentia f pollicis longa. Corolla tubulosa aurantiaca pollicaris, 

 tubo gracili recto rubro, lobis inferioribus oblongis spalhulatis 

 rotundatis, superioribus angustioribus aurantiacis. Stamina longe 

 exserta pollicaria gracillima rubra. AntheraB perparvfe lineares

Singapore, in dense wet woods in Choa-Chu-Kang. 



This is a very beautiful and interesting plant, and well worthy 

 of cultivation. In habit it approaches C.yzs^u/os;<»i Becc, but the 

 inflorescence is rather that of C. paniculatum L. It is an un- 

 branched or few-branched shrub, with a smooth pale-coloured stem 

 about 3 ft. tall, the internodes dilated, and, except when quite 

 young, hollow. In some of the internodes, but by no means all, 

 ants make their nests. The ants that I have found belong to a 

 species of Pheidole allied to P. megacephala Fabr., I am informed by 

 Mr. Waterhouse. In Beccari's C. Jistulosum the inhabiting ants 

 belonged to the genus Colobopsis.
