558 cxxxvi. URTiCACEJi. (J. D. Hooker.) [Pilea. 



long, red-brown with obtuse edges. The material for this species is fern, only, nml 

 quite insufficient. Weddell describes the achene as marbled and smooth not granular, 

 I find a herbaceous granulate coat covering a smooth endocarp. 



18. P. obliqua, HooJc.f. ; glabrous, stem slender, leaves 3-5 in. long- 

 petioled broadly obliquely ovate acuminate serrulate 3-nerved, base roundtMl 

 or cordate, stipules oblong, cymes slender long-peduncled, fern, dorsal sepal 

 longest, achenes minute straight with an intramarginal rugose or granular 

 ridge, the faces nearly smooth. 



SIKKIM HIMALAYA, alt. 1000 ft., and KHASIA MTS., at Nunklow, alt. 3500 ft., 

 Clarice. 



The very oblique broadly ovate leaves of this species which is a native of low 

 levels, and the concentric ridge on the otherwise nearly smooth achenes which are 

 only -gL in. long, are its best characters, otherwise it is very near P. bracteosa. 



DOUBTFUL AND IMPERFECTLY KNOWN SPECIES. 



19. P. cordifolia, HooTcf. ; tall, stout, quite glabrous, leaves large 

 broad long-petioled oblique orbicular-ovate or elliptic cuspidate or acuminate 

 obtusely serrate 3-nerved, base cordate or rounded, petiole 3-6 in., stipules 

 rather large broad persistent, male cymes very long-peduncled paniculately 

 branched, sepals obtuse, dorsal of fern. fl. longest. 



SIKKIM HIMALAYA, alt. 7000 ft., J. D. H., at Rungbee and Darjiling, alt. 5000- 

 6500 ft., Clarke. KHASIA MTS., at Churra, alt. 3-5000 ft., J. D. H. #T. T. 



Much the largest leaved Indian species. Stem 2-4 ft. or more, rooting at the base. 

 Leaves attaining 6 in. broad ; petiole 4 in. ; stipules % in., green broadly triangular 

 obtuse. Cyme with divergent branches and branchlets. Achenes minute, immature. 



Weddell has named one Sikkim specimen P. trinervis, which- it does not resemble, 

 and a Khasia one P. bracteosa. 



20. P. firuticosa, HooTc.f.; shrubby, quite glabrous, stem branched 

 terete woody, leaves 3-4 in. long-petioled in equal pairs elliptic or elliptic- 

 lanceolate acute at both ends obscurely obtusely serrate 3-nerved, stipules 

 very short, male cymes sparingly branched, peduncles longer than the 

 petioles, flowers in small remote clusters minute, fern, cymes small sessile, 

 flowers crowded, dorsal sepal longest, achenes very minute with an intra- 

 marginal granular ridge. 



PERAK ; at Goping, King's 'Collector. Nearly allied to P. smJlacifolia, but the 

 steins ate quite terete, and the minute acheues \, in. long are very different. 



P. GRIFFITHII, Elume Mus. Sot. ii. 55; Wedd. in DC. Prodr. xvi. i. 131, is 

 not recognizable from the description. Weddell had not seen it, and there is no 

 Malaccan Pilea in Griffith's collection at Kew. Miquel doubtfully refers it to P. 

 stipulosa, from which Blume says it differs in the lateral nerves produced to the tip 

 of the leaf, and in the caducous stipules. 



P. PRODTTCTA, Blume I.e. 56; Wedd. Monogr. 265; DC. I.e. 136, from the 

 Himalaya, distinguished by its authors from P. umbrosa by the leaves narrowed into 

 the petiole and the more shortly peduncled cyme-, is no doubt referable to thut 

 plant. 



P. HYGROPITTLA, Blume 1. c. 56; Wedd. Monogr. 264; DC. I. c. 135 ; Niq. Fl. 

 Ind. Bat. i. ii. 237. Urtica hygrophila, Miq. PL Jungh. 28, is probably a mixture, 

 being described as having the fern, sepals either all of the same size, which would 

 answer for a Ceylon plant of Gardner's (P. stipuhsa), or with the dorsal larger, 

 which would answer for the Khasian plant, whatever that may be. TheNilghiri one i-; 

 probably Wightiana. The type of the species, Miquel's Javan Urtica hygroplula, is 

 unknown to me ; it is described as having the fruiting perianth one-half longer than 

 the achene, which I have seen in no Indian species.
