Coll. Sanct. Xavie- ri, Bombay. Invenit quoque in Herb. Talbot, 3740 a Siddhapur.

A very distinct species, witb tbe habit and conspicuous flowers of L. longifolia Bentb., but a very different calyx, resembling a small form of the calyx of L. linijolia Spreng.

Christisonia flammea L. J. Sedgwick, Sp. nova. Eerba humilis, in Strobilanthis radicibus parasitica. Caules aggregati, demum erecti, tantundem elongati ut flores e tellure emergant, 4 mm lati. Squamulae 5x4 mm, distantes, ovatae, obtusae. Flores in racemis congestis, corymbiformibus ; bracteae squamulis assimiles, sed majores : bracteolae 2. Pedicilli 0, vel ad 2 cm longi. Calyx rufo-brunneus, dense et conspicue puberulus ; tuba ad 2 cm longa, 1 cm lata, pentagona ; lobi 5, aequales, triangulares, 5 mm longi. Corolla aureo-lutea, ad 5 cm longa, bucciniformis ; tuba a medio inflata, extus dense pu- berula ; lobi 5, aequales, curtissimi, perobtusi, demum patentes. Stamina corollae dimidio aequantia, didynama ; filamentaalba, puberula ; antherae conniventes, crescentiformes ; loculus superior apice infra porum subulatus ; loculus inferior sterilis, commatiformis. Stylus stamina longe excedens, albus, glaber; stigma bilobum ; lobi crassi, rotundati. Ovarium biloculare. Capsula globosa, 12 mm lata, styli basi persistonte apiculata. (See Fig. p. 127.) In Sfcrobilanfcbis variaruni specierum radicibus parasitica, apud Gairsoppa Falls in Canara, sed solum in flurninis australi, id est My- sorensi, ripa observata, ad alt. circa 1500 ped. angl. et pluv. 150 — 200 digit, angl. Collegerunt Bell, Sedgwick, Hallberg et McCann, Nov. 1919. In herbario Sedg. et Bell. Cotypi in berbario Coll. Sanct. Xavieri, Bombay.

Apparently exceedingly close to C. aurantiaca Wt. Ic. 1486, wbicb was united with C. bicolor Gardner by Hooker in F. B. I. IV p. 322. The drawing in the Icones however shows a less elongate and less ele- gant type of flower. The calyx is broader and conceals more of the tube of the corolla. In the plant from Gairsoppa the calyx is much narrower, and the slender corolla tube is clearly exerted.

Phyllanthus Talboti L. J. Sedgwick, Sp. nova. Frutex erectus, ad 1 m altus, in rivorum tluminibus saxicola. Caulis saepius simplex, nigrescens, striatus. Rami crebri, ad 15 cm longi, exceptis tenellis glabri. Folia numerosissima, creberrima, disticha, patentia, sed in herbario secunda, a 3'5 X 1*5 mm ad 9 X 3'5 mm, oblonga, acuta, supra glabra, subtus glabra, glabrescentia, vel puberula. Stipulae a basi lata lineares, Flores masculi in omni axilla fasciculati ; pedicilli ad 3 mm longi. Calycis lobi 4, imbricati, late ovati, obtusi, dorso saepius minute sericei, marginlbus integris seariosisque. Discus 4- lobatus ; lobi magni, rotundati. Antherae 4, in summae columnae margine transverse dispositae. Flores feminei in axillis solitarii ; calycis lobi 6, imbricati, ovati, glabri, marginibus integris. Discus annularis. Ovarium stipitatum, 3-loculare, albis tubercellis subs- cabridum ; styli 3, altebifidi, reflesi. Cocci distinct!, dorso rotundati, supra producti et stylos excedentes, scabridi, sed deinde glabri, et ab axi separate decidui. Semina glabra, lutea. (See Fig. p. 129.)

In fluminibus Canarae in Provincia Bombaiensi, apud Supa, Sedg. et Bell 4869, Nov. 1918, et apud Jog (Gaisoppa) Talbot 828, A.D. 1883, Sedg. et Bell 7073, Nov. 1919. Utriusqe loci alt. circa 1500 ped. angl. ; pluv. circa 100-200 digit, angl.

This was passed over by Talbot as being P. Laioii Graham, the habitat being the same. But it differs from that species in habit, the plant being taller, and the branches much longer and less rigid. In the structure of the male flower it is, of course, quite different, P. Laioii having three erect acute anthers. It belongs to Hooker's Sec. Biedia.

Ceropegia fantastica L. J. Sedgwick, Sp. nova. Planta volubi- lis. Radix haud visa. Rami longi, tenues, perdistanter foliosi. Partes maturae glabrae ; ramuli tenelli, pedunculi et pedicilli capillis vacuis, pellucidis, multicellularibus vestiti. Fetioli 15 mm excedentes. Folia 10 cm excedentia, lanceolata, sensim caudato-acuminata, glabra vel glabrescentia, nervis perobliquis, conspicuis, irregularibus. Inflorescentiae interpetiolares, cymosae, aut distanter aut dense floriferae. Pedunculi 6 cm excedentes. Pedicilli aut longi aut perbreves. Bractecz et bracteolac peranguste lineares, ad 5 cm longae. Calyx ad basim partitus ; segmenta bracteis et bracteolis similia, semper corollam longe excedentia. Corolla 4 cm longa, in partibus apicali basalique inflatis 11 mm, in tuba 8 mm lata, colore (ut ex siiccoexemplo videatur purpurea, lineis maculisque luteis veriegata. Coronae forma in exsiccato exemplo haud determinari potuit. Folliculi perangusti, 90 x 3 mm, cinerei, tenuiter striati ; semina 8x3 mm ; coma 20 mm, copiosum, molle.

Apud Sulgeri, in Canara, in Provincia Bombaiensi, ad alt. 500 ped angl., et pluv. circa 200 dig. angl. Coll. T. R. D. Bell, CLE. mense Augusto, id est in medio tempore pluviali, 1918 ; in herb. Sedg. et Bell. 4252.

A curious species, at once recognisable by the enormously long and fine calyx segments, bracts and bracteoles. The corolla is in general shape typical of the genus, the segments of the swollen apical portion meeting at their tips. The corona was quite indistinguishable in soaked out flowers.

Boucerosia truncato-coronata L. J. Sedgwick^ Sp. nova. Planta carnosa, glabra, diffusa, ramis numerosis ad 15 cm altis. Radices crassae, succulentae. Rami 6 mm lati, supra haud attenu- ate quadrangulares, faciebus alte sulcatis, et in angulorum tuber- culis folia minutissima ovata ferentes. Inflorescentiae terniinales, exacte unbellatae, (in exemplo viso) 13-florae. Bracteae 2-5 mm longae, lineares. Pedicilli 17 mm longi. Calyx ad basim partitus ; segmenta 4 mm longa, linearia, acuta. Corolla tuba 6x6 mm, camp- anulata ; limbo in aestivaiione 5 segmentis triangularibus, valvatis exacte pentagono et in summo piano, 8"5 mm Iato ; (segmenta in anthesi utrum erecta sint an patentia haud satis notum, sed, at videatur, erecta) ; extus viridis, sed in limbo paullo purpureo-maculata, intus purpurea, vel prope nigra, fossiculis numerosissimis, luteis, pellucidis, linearibus, quae in cincturis interruptis dispositae sunt, insignata ; inter segmenta in sinibus paucas particulas clavatas ferens. Androecium cum gynoecio parvulum, in corollae basi situm. Anther ae quadrato-oblongae, obtusae, supra stigmatis discum incurvatae, approximatae sed non contiguae, in dorso sulcatae, colore luteae. Pollinia in cellulis solitaria, luteorubra, compressa, erecta, sed latere caudiculis minutis ad translatorem erectum purpureum affixa. Corona staminalis, duplex, crassa, ut corollae interior pars colorata ; lobi exteriores 5, truncati, sed in utroque latere minutissime cornuti ; interiores ligulati, elongati, adscendentes et in antherarum dorsales sulcos appressi. Folliculi haud visi. In ariclo colle, sub fruticibus diffusa, apud Hubli, District Dhar- war, in regione Carnatica Provinciae Bombaiensis, ad alt. 2000 ped. angl., et pluv. 30 digit, angl., mense September, 1919 ; coll. ipse.

An inconspicuous plant with elegant flowers. Differs from the other Indian species in having the bifid corona lobes reduced to a broadly truncate top with minute horns or teeth at each end.

Bracteae angustissimae, secundae ; bracteolae lineares vel etiam subulatae, secundae. Flores pro rata magni, cymose dispositi in ramis, aggregati, secundi. Calyx 7 X 1-5 mm.; tuba 5 mm. longa, striata, haud alata ; dentes 2 mm. longi, lineares, erecti. Corolla rosea, 10 mm. longa ; tuba 5 mm. lobi 4, in aestivatione imbricati, uno exteriore, vix contorti, valde inaequales ; 2 majores orbiculares, 2 minores oblongi, obtusi. Stamina 4, subaequalia sed unius filamento in corollae tuba paullo altius affixo, et supra decurvato : antherae subaequales, 2 mm. longae, subversatiles. Stylus filamentis longe excedens, stigmate breviter bilobato. Ovarium oblongum, angustum. Capsula cylindrica, 3 x 1*5 mm., nigrescens ; semina irregulariter polygona, nigrescentia. (See fig. p. 131.)

In saxosis planis intra nemora, apud Castle Eock, in District North Kanara, Provinciae Bombaiensis, ad 1600 ped. angl. alt., et circa 200 dig. angl. pluv., collegerunt T. E. D. Bell, CLE. et L. J. Sedgwick, mense Decembre A.D. 1917. Herb. Sedg. et Bell. 3393.

A member of the flora found on sheet rock in forest clearings. Differs very materially from all other Bombay species in the very simple, strict, erect habit with crowded, narrow bracteoles and flowers ; the calyx neither winged nor keeled but striate. One or two

very small broadly ovate leaves were found on the stems ; but as those are almost certainly not typical vegetative leaves they were excluded from the description.
