nearly all named for me later by Dr. A. Kerr, the government 

 botanist in Bangkok. Near the foot of the mountains we met 

 with the beautiful Miissaenda hossei Craib, with large white 

 calyx lobes. This shrub was described from Doi Sutep : the genus 

 extends to tropical Africa in one direction, and Polynesia in the 

 other. On the trail we picked up the very large flowers of the 

 Bignoniaceous Markhamia stipulata Seem. Elaeocarpaciae 

 were represented by Elaeocarpus robertsonii Gamble, a very fine 

 thing. The Convolvulaceous Parana racemose Roxb., a smallish 

 delicate form, with flowers in clusters was especially interesting 

 to me because I had collected fossil Parana at Florissant, but 

 had never seen a living specimen before. The Acanthaceae were 

 rather conspicuous, including the large flowered Thunhergia 

 laurifolia Lindl. and Strohilanthes pentstemonoides T. Andr., 

 and Daedalacanthus tetragonus T. Andr. {Eranthemiim tetrago- 

 nuni), a rather phlox-like plant with pink flowers and long slen- 

 der opposite leaves. 



In a wet place near the Queen's Garden, about half way up, 

 the small pink flowered spikes of the Lythraceous Rotala rotundi- 

 folia Koehne were conspicuous. I did not see it anywhere else. 

 Large oaks in the gulches on the slopes proved to be Quercus 

 semiserrata Roxb. I picked up an oak-coccid of the genus Ker- 

 mes, the genus new to Siam, and the species probably undescrib- 

 ed. The mountain is famous for its oaks; I found ten listed in 

 the literature, and Dr. Kerr tells me there are still others. Four 

 species (Q. garrettiana Craib, Q. kerrii Craib, Q. kingiana Craib 

 and Q. sootepensis Craib) were based on Doi Sutep specimens. 

 Of the others, one ranges to Java and Formosa (the nut is edible 

 and it may have been carried about), but most extend into Bur- 

 ma or Assam. There are also three species of Castanopsis on the 

 mountain. Malvaceae were represented by Thespesia lampas 

 Dalz. & Gibs., the name apparently referring to the rather lan- 

 tern-like five parted fruit. Another five parted fruit belonged 

 to the genus Schima [S. waUichii Choisy or S. brevipes Craib), 

 one of the Ternstraemiaceae, — also belonging to the latter fam- 

 ily is Anneslea fragrans Wall, with fine dark red flowers. As 

 might be expected, Leguminosae were common; those collected 

 included Crotalaria ferniginea Grah., with yellow flowers; the 

 large flowered Bauhinia variegata L.; the creeping Dolichos sub- 

 carnosus Prain ; Lespedeza pinetoriim Kurz, with long three-part-
