branches brachiate, calyx-teeth linear or filiform many times longer than the 
ovary persistent and exceeding the diameter of the fruit, corolla glabrous, tube 
i in. twice as long as the lobes. I. tomentosa, Tim, Enum, 156. 
Cryton; at Damboul, and abundant in the Batticaloa district, Walker, Thwaites. 
Of this remarkable plant there are two forms, one quite glabrous, green when dry,. 
with leaves 5 in. long; it is in fruit, and has very slender peduncles and pedicels, and 
filiform ealyx-tecth nearly } in. long crowning the ripe fruit; the other is more or 
less black when dry, softly velvety all over, with smaller broader leaves 23-3 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 anytbing 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. compactirtora, Kurz in Journ. As. Soc. 1872, ii. 815; 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 involucred heads 1 in.. 
diam. terminating axillary branches, involuerate bracts small inconspicuous broad 
ovate imbricate, calyx-teeth oblong rounded, corolla-tube + 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. 
PS ARISTATA, Wall, Cat. 6169, from Tavoy ` the specimens have no flowers; the 
name suggests its being possibly Webera stellaris, with which the foliage agrees, as do- 
its 5 calyx-teeth. 
Pa optonca, Wall. Cat. 6170 (“ Herb. Finlayson” from Siam?) is pentamerous: 
and a Webera. 
P.? correacea, Wall. Cat. 7290, is probably Webera attenuata, 
68. COFFEA, Linn. 
Shrubs, branchlets compressed. Leaves opposite, rarely in threes ; stipules 
broad. Flowers in axillary fascicles or cymes or solitary, 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. Anthers 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 Drupe with 
9 plano-convex or ventrally coneave coriaceous or cartilaginous pyrenes. Seeds 
plano-convex, concave or grooved ventrally, albumen horny; embryo short, 
towards the base of the seed, curved, cotyledons thin cordate, radicle inferior. 
—DisrRIB. Species about 20, in the tropics of the old world. 
Coffea arabica, the coffee plant, is abundantly cultivated in various parts of 
Southern India.
