it seems to be more acid at times, so as to be used in making a 
lemonade- like drink. I do not recall its native name, but if it 
s the ep mentioned, it is called “Aguava,” “Cardo,” or 
“Timbiri ichi.’ 
One of the most important commercial table fruits of Mexico 
is the grenadilla, which is a species of Passiflora, or passion flower. 
Having never seen its foliage or flowers, I am unable to name 
it specifically. In middle or late winter, it may be seen in 
bushels on all fruit stands. Its skin is rather hard and thick, 
like that of a gourd, and it contains a myriad of blackish seeds 
nearly colorless and transparent sweet jelly. This jelly may be 
sucked from the seeds and the latter rejected, though it is more 
common to swallow the mass entire like an oyster. In Bolivia 
I have seen one almost exactly similar, though rather smaller, of 
which the pulp is cid sour like that of a lemon, and which 
is used for an acid dri 
Altogether the most i eeeceeng fruit which I encountered is 
one which is almost wholly unknown either economically or 
scientifically. It is exceedingly rare, even where it occurs, and 
appears to be in the process of extinction, and specimens of it in 
herbaria and other collections are almost non-existent. The 
us Mocinna was described by Ramirez in 1894 in a Mexican 
governnet publication and is merely referred to in the Nachtrage 
e Pflanzenfamilien. I was exceedingly fortunate in finding 
at Seis de Gonzales a single plant in flower and later one 
in fruit. Looking at the fruit as here exhibited, you would say 
that it had a short, stout, curved peduncle and five terete, rigid, 
horn-like or spine-like, erect, superior calyx teeth 
it attached, however, we find it inverted, the calyx-teeth be- 
ing reflexed, the supposed peduncle a style, and the real peduncle 
extremely long and filiform, and the fruit pendulous. This re- 
markable fruit is classed with the papaw, or papaya, sili to 
me it seemed more closely related to the passion flow It 
grows prostrate among rocks, its stems being very ena and 
slender and much like those of the Cucurbitaceae. It bears no 
tendrils. The fruit is known as “‘Jarilla’” and is greedily sought
