Most of the plants enumerated were collected by J. C. White 

 during a tour along the borders of Tibet and Bhutan and a visit 

 to Pari and Punakha in May— June 1905 supplemented b} 7- a col- 

 lection in E. Bhutan in 1906—7. From these collections there are 

 described as new Euonymus tibeticus, Pirus bhutanica, Primula 

 Whitei, P. Jonarduni, and Buddleia tibetica. Other new species descri- 

 bed are Garuga Gamblei King mss., Saxifraga Gageana, Pimpinella 

 radiata, Pentapterygium sikkimense, Aerides Greenii and Hedychium 

 Greenii. W. G. Craib (Kew).

Holm, T„ Medicinal plants of North America. 57. Ampe- 

 lopsis quinquefolia L. C. Rieh. (Merck's Report. XX. p. 309—311. 

 Nov. 1911.) 



The leaves and twigs were used by the eclectics as an aitera- 

 tive, tonic and expectorant; they contain tartaric aeid, glycollic aeid, 

 paracatechin and inosit. The plant is figured and described, and 

 characteristic of the seedling is that already the first leaf sueeee- 

 ding the cotyledons shows the typical, quinquefoliate form; the 

 primary root is short, but several secondary roots develop soon from 

 the base of the long, erect hypocotyl; the cotyledons are petioled 

 with the blade ovate, entire, of exactly the same shape as those of 

 Vitis from the Atlantic States. In respect to the root-strueture it 

 was noticed that increase in thickness takes place at a very early 

 stage, and in the usual manner. Cells with rhaphides and aggregated 

 crystals oeeur in the secondary cortex. In the stein was noticed 

 that the cork develops from the hypodermal Stratum of cortex, that 

 stereome appears in the secondary cortex, and that the stereids of 

 the libriform are septate. The midrib of the leafiet is stelo'i'd, being 

 composed of several, mostly six, collateral mestome-strands enclosing 

 a narrow but distinet pith. There is a Single Stratum of high pali- 

 sades on the ventral face covering a very open pneumatic tissue, 

 large rhaphide cells are interspersed in both these tissues. In the 

 upper part of the petiole are about eighteen collateral mestome- 

 strands arranged in a Single band around a starch-bearing pith.

Holm, T., Medicinal plants of North America. 58. Magnolia 

 glauca L. (Merck's Report. XX. p. 336—339. fig. 1-17. Dec. 1911.) 



The drug Magnolia is yielded by the bark of the twigs and 

 roots; that of the roots being deemed the most emeient; it contains 

 magnolin. while the leaves contain a volatile oil of a bright green 

 color, and with an odor resembling that of fennel or anise. Magnolia 

 is a gentle stimulant aromatic tonic and diaphoretic. The plant is 

 described and figured. The thin lateral roots are mycorrhizae; the 

 cork develops from the outermost Stratum of the cortex, just inside 

 the exodermis, a root-strueture known only from a ver3 T few plants:
