PLANT EXPLORATION AND INTRODUCTION

January 1$, 1939

Dr. Ivan Johnston,

The Arnold Arboretum,

Harvard University,

Jamaica Plain, Mass.

Dear Doctor Johnston:

Enclosed is the list of names of the grasses received
from you some time ago. We are delighted to have these grasses.

No. 7132 is a species new for North America. I have referred it
tentatively to Sporobolus phleoides Hack, from Cordoba, Argentina.

The type of this in the Hackel Herbarium consisted of three pani¬
cles only, not a leaf present. It is a Stuckert specimen and I
understand the Stuckert grasses sent to Hackel were all returned

sor Hackel kept. The Stuckert

Herbarium in Geneva, but when

I was there in *22 Dr. Briquet said that Stuckert had left strict
orders that the cases were not to be opened. The panicle and spikelets
are very like yours, but two collections from Argentina with the same
kind of panicle have a base somewhat different from yours. In any
case it is a wonderful find. The species will be worked out definitely
for your Flora.

No. 7358 is an over mature specimen of Bouteloua that does not
fall into any species of Bouteloua. Mr. Swallen has done the Chlorideae
for the North American Flora and has Bouteloua well in mind. He hesi¬
tated to send this in as an addition to his manuscript because the
specimens are well past maturity. We hope on your next trip that ycu
may be able to collect this species again.

I was delighted to see Muhlenbergia repens from Mexico. The
type was collected in Mexico, and, so far as we know, the species
has never since been found south of the United States.

You see what a thrilling lot of grasses you sent us. We are
eagerly awaiting results of your next trip.

Sincerely yours.

Agnes Chase, Senior Botanist
