Tavetta.] lxxy. EUBiACEiE. (J. D. Hooker.) 153: 



'brandies brachiate, calyx-teeth linear or filiform many times longer than the 

 ovary persistent and exceeding the diameter of the fruit, corolla glabrous, tube 

 ^ in. twice as long as the lobes. I. tomentosa, Thv. Enum. 156. 



Ceylon; at Damboiil, and abundant in the Batticaloa district, Walker, Thwaites. 



Of this remarkable plant there are tTro forms, one quite glabrous, greou when dry, 

 ■with leaves 5 in. long ; it is in fruit, and has very slender peduncles and pedicels, and 

 filiform calyx-teeth nearly \ in. long crowning the ripe fruit; the other is more or 

 less black when dry, softly velvety all over, with smaller broader leaves 2J-3 in. long ; 

 it is in flower, and has shorter calyx-teeth in the fruit. Thwaites first regarded this 

 as a form of P. indica, var. tomentosa, with longer calyx-teeth ; but variable as that 

 plant is, I have seen no specimen from any part of India with anything but very short 

 triangular calyx-teeth, nor any with the inflorescence of this, in which the leaves at 

 the end of the axillary flowering branches are wholly suppressed. 



DOUBTFUL SPECIES. 



p. coMPACTiPLOEA, Ktirs in Journ. As. Soc. 1872, ii. 315; For. Fl. ii. 17 (Ixora); 

 quite glabrous, leaves 3-5 in. elliptic to broadly lanceolate acuminate tapering into 

 the stout petiole blackish when dry, flowers subsessile in dense iuvolucred heads 1 in^ 

 diam. terminating axillary branches, involnerate bracts small inconspicuous broad 

 ovate imbricate, calyx-teeth oblong rounded, corolla-tube j- in. rather wide, lobes ob- 

 long obtuse equalling the tube. — Upper Tenasserim, alt. 2000 ft., Kurz. — Possibly a 

 Webera, though placed by Kurz along with tetramerous species. 



P. ? ARisTATA, Wall. Cat. 6168, from Tavoy ; the specimens have no flowers; the 

 name suggests its being possibly Webera stellaris, with which the foliage agrees, as do- 

 its 6 calyx-teeth. 



P. ?0BL0NGA, Wall. Cat. 6170 ("Herb. Pinlayson" from Siam?) is pentamerous^ 

 and a Webera. 



P. ? coFFEACEA, Wall, Cat. 7290, is probably Webera attenuata. 



68. COXTEA, Xum. 



Shrubs, branchlets compressed. Leaves opposite, rarely in threes ; stipules 

 broad. Flowers in axillary fascicles or cymes or solitaiy, white or yellowish, 

 often scented ; bracteoles often connate. Calyx-tube short ; limb short, often 

 glandular, persistent. Corolla-tube short or long ; lobes 4-7, spreading, twisted 

 in bud. Antha-s 4-7, sessile on the corolla-tube or throat, narrow, often re- 

 curved and twisted. Ovary 2-celled ; style filiform, smooth, branches linear or 

 subulate ; ovules 1, peltately attached to the septum in each cell. Ih'wpe with 

 2 plano-convex or ventrally concave coriaceous or cartilaginous pyrenes. Seeds 

 plano-convex, concave or grooved v-entrally, albumen horny; embryo short, 

 towards the base of the seed, curved, cotyledons thin cordate, radicle inferior. 

 — DisiElB. Species about 20, in the tropics of the old world. 



Coffea arabica, the coffee plant, is abundantly cultivated in various parts of 

 Southern India.
