What kind of a plant Is Bchinopsis castanea iL' ngelnr ?7 It 

 appears In the cataloc-ue of Lenke in Leipzig, 



A 10* 1 high, 4 year old seedline: plant of Ger , tuberosus P. cane 



into flower on July ft&tf&\ it had an irregulär »round, brown tubercle of 



5/8* diameterjout of who f se depressed raiddle arose the slender , pretty 



plant. The lower part of it to a heirth of 2 W is very thin, round,, 



wood-like, smooth a^d brown, Purtherup the plant is not quite 3/8" 



strong, with 8 ribs, almost round, with rlbs,which protrude very little, 



and, until now, without any branchlng; the spihes are all whiteish, 



central 



only at the end of each years growth are the/spines pointed upward & 

 black, Most curious of this is, that the flower is positioned on the 

 very tip of the stem and forns its continuation, in such a way, that 

 the transition of the 8 ribs Bife^ttefe» into the sequence of areoles 

 of the calyx tube can be observed.The calyx tube is 1 H long, and at 

 its end | fl wide, brownish-green, covered with spirally formed, white- 

 woolly areoles.The areoles protrude strongly, and carry 6-8 f ine, 

 hair-like, white beards, and carry in their raiddle a Short, soft calyx 

 scale. One can easily distinguish the 8 larger,lancet-shaped sepals , 

 the outer ones reddi sh-brown, the inner ones raore bluei s&-red. - The 

 petals are 16 lancet-shaped , te^rainating in a fine tip, 1 M long, faint- 

 reddish with a darker raiddle stripe going into bluei sh-red. Staraens

 raens with 8-divided, green scar. The flower keeps open only in half 

 sunshine for several days with a diaraeter of 2\ H . Toward evening- it 

 closes partially. - If the plant is your _C» genioulatus you will be 

 able to decide after exaraining the living specinen, which I an sen - 

 dinff you; I alraost believe, that both are identical. I do want to 

 add the reraark, that the color of this first blossom is much nore
