as are the primary reticulations ; petioles pubescent, 5 to 10 mm

 the branchlets, the panicles rather densely pubescent, up to 18 

 cm long, the peduncles up to 1 cm in length. Heads 1.5 to 1.7 

 cm long, about 20-flowered, the outer bracts oblong to oblong- 

 ovate, 2 mm long, the inner ones lanceolate, acuminate, about 

 10 mm long, 2.3 mm wide, all rather densely cinereous-pubescent. 

 Achenes 4 mm long, longitudinally sulcate, entirely glabrous; 

 pappus copious, somewhat tawny, about 10 mm long.

 38886 (type) Ramos & Edano, June, 1920 : Lanao District, Camp 

 Keithley, Mrs. Clemens 1086, May, 1907. In damp forests at 

 an altitude of about 1,000 meters. Locally known in Bukidnon 

 as gauod. 



A species belonging in the group with Vernonia philippinensis 

 Rolfe, apparently most closely allied to that species, differing 

 especially in its entirely glabrous achenes. 



LACTUCA Linnaeus 

 LACTUCA INTEGRA sp. nov. 



Herba erecta, glabra, ramosa, usque ad 40 cm alta; foliis 

 chartaceis, lanceolatis ad oblongo-lanceolatis, acutis vel leviter 

 acuminatis, usque ad 7 cm longis, radicalibus numerosis, petio- 

 latis, confertis, caulinis quam radicalibus multo minoribus, 

 sessilibus, nervis reticulisque obscuris; capitulis corymbose- 

 paniculatis, pedicellatis, 6 ad 7 mm longis, bracteis exterioribus 

 parvis, interioribus plerumque 8, circiter 6 mm longis, glabris, 

 anguste oblongis, obtusis ; acheniis oblongis, 3 ad 3.5 mm longis, 

 longitudinaliter costatis, glabris, sursum leviter angustatis. 



An erect, glabrous, branched herb about 40 cm high, oli- 

 vaceous or brownish olivaceous when dry. Radical leaves very 

 numerous, crowded, chartaceous, lanceolate, subequally nar- 

 rowed at both ends, 5 to 7 cm long, 1 to 1.5 cm wide, entire, 

 shining, acute, base decurrent; petioles up to 2 cm long; lateral 

 nerves slender, obscure, anastomosing. Stem leaves much 

 smaller than the radical ones, lanceolate to ovate-lanceolate, ses- 

 sile, entire, acute, base obtuse to rounded or somewhat cordate, 

 somewhat clasping the stems, 1.5 to 4 cm long, the upper much 

 smaller than the lower ones. Branches few, scattered, up to 

 18 cm long. Heads corymbose-paniculate, 6 to 7 mm long, ped- 

 icellate, the outer bracts small, few, 2 mm long or less, the 

 inner narrowly oblong, obtuse, 5 to 6 mm long, about 1 mm 

 wide, glabrous. Flowers few, about 10 in each head. Corolla
