ed leaves, pale beneath; and Desmodium floribundum Sweet 

 {Meibomia floribunda) . The genera are very familiar to Ameri- 

 can botanists. Baiihinia is everywhere conspicuous in the Siam- 

 ese jungles, with several species. Similarly, the Compositae 

 have for the most part a familiar aspect. I obtained Vernonia vol- 

 kamerifolia D. C, with large heads or clusters of heads; Agera- 

 tum conyzoides L., a well-known tropical weed also found in 

 Panama ; A naphalis margaritacea B & H , (I suppose it was the va- 

 riet\' cinnamomea Clarke) ; Senecio nagensium C. B. CI. var. lob- 

 6// Hook, fi., a robust species with large leaves, pale below; Lag- 

 gera flava Benth., with yellow flowers ; 5i<fe«5 pilosa L., a cos- 

 motropical weed with white rays, a Gynura with white pappus, 

 and some others. There was a Vernonia with dark-tipped involu- 

 cral bracts, new to Dr. Kerr, and possibly undescribed. On and 

 about the summit were many ferns, Pteridiiim aquiliniim and 

 species of Pteris, Cheilanthes and Drynaria. Two grasses, Im- 

 perata arundinacea Cyr., with a long spike, and the tall Pollinia 

 grata Hack., were especially conspicuous. The flora on the sum- 

 mit included a number of species characteristic of temperate re- 

 gions. Riibus kerrii Rolfe, with leaves pale below, was origi- 

 nally described from this locality. Two species of Po/j'gowzmz, one 

 a Persicaria-like species referred to P. chinensis L. var. and the 

 other a large robust plant doubtfully determined as P. damron- 

 gianiim Hosseus. Some of the Polygonum was heavily infested 

 with the fungus Ustilago utriculosa, for the name of which I am 

 indebted to Dr. Seaver. I was very much pleased to find Viola 

 serpens Wall., with pale flowers. It was originally described 

 from Nepaul. There are three other species of Fio/a in the Si- 

 amese flora. My wife collected the orchid Eulophia nuda Lindl. 

 on the summit. The large Lilium nepalense D.Don, common 

 on the summit, had gone to seed, but we collected seeds and dug 

 up a bulb which was sent to Kew. This species flowered in the 

 garden of Trinity College, Dublin in 1923. A quite dift'erent 

 liliaceous plant was Dianella ensifolia Red.; I later (April 15) 

 saw the genus again in Australia, finding D. tasmanica'xn Upper 

 Fern Tree Gully, Victoria. The slender Impatiens violiflora 

 Hook, fi., with knobbed glands, served to remind us of the fa- 

 mous botanist who specialized on /m/>a//e«5 when over 90 years 

 old. A very interesting and curious plant of the summit, very 

 small, with a long red corolla, proved to be the Gesneriaceous
