ESPOSTOA 
This beautiful genus was founded by Brit- 
ton G Rose in 1920 on Cactus lanatus of Hum- 
boldt, Bonpland and Kunth who described their 
collections in 1823. Columnar plants with 
numerous low ribs; plants upright, branching; 
areoles with strong spines and bearing long 
white hair. Flowers small, nocturnal, white with 
outer segments pinkish, short campanulate, 
nearly hidden in the dense psuedocephalium 
developed on flowering stems. Tube short, 
stamens and style included. Scales on ovary 
and tube small, acute the axils with long, 
silky, caducous hairs. Fruit subglobose to 
broadly obovoid, smooth, red or white, with 
white flesh, sometimes fragrant, very juicy, 
acid, edible. Seeds small black, dull. 
This genus has been much mixed up due to 
lack of information. Dr. Rose included the dis- 
tinct species from above Lima, Peru with the 
plants from northern Peru (the true E. lana- 
tus). His photographs and figures 88, 89, 90 
and 91, Vol. 2 are Backeberg’s Psuedoespostoa 
which was separated because of its glossy seeds 
and basal branching. The flowers are nocturnal 
not diurnal as stated by Mr. Backeberg. This 
Psuedoespostoa is found also north of Lima 
where the spines are more prominent and shine 
with a purplish glint in the sun. Mr. Akers 
and | found four other distinct species of Es- 
postoa between Lima and Chiclayo and at 
Huanuco on the Atlantic drainage. The plants 
are of easy culture enjoying a light, porous soil 
and a sunny or light position. Keep dry in 
winter. They are liable to be injured below

Espostoa huanucoensis. A lovely species (not

plant has a soft yellow color. The seedlings are 
stout. The plant when mature is 6’ - 8’ tall, 
divaricately branched — 1 counted as many as 
50 branches — some rising from near the base 
and producing secondary branches. Flowers as

Espostoa mocupensis. This is a very tall 
plant, to 15’ with a few ascending branches. 
Ribs low about 20, straight; areoles proximate, 
rather large, felted with many wispy white 
hairs; radial spines about 40 about 14” long 
the lateral ones about 25, straw yellow, the 
central more erect ones shorter and red brown. 
Central spines often wanting, porrect, grey to

tinged pink, lost in the not too Juxuriant 
psuedocephalium. Fruit bright red, odorless, an 
inch in diameter. A very beautiful species.

ARMATOCEREUS 
A genus erected to include the South Amer- 
ican Lemaireocereus. The plants appear very 
much like Lemaireocereus but are generally 
far more wickedly spined and some that | have

normal branches have a woody axis while often 
on the tips of these branches are borne much

PRINCESS OF THE NICHT 
A glorious blossom and one of the largest in the 
cactus family. Selenicereus pteranthus is the most satis- 
factory and freest in bloom of this group. Grows rap- 
idly and without special care, flowering during the sum- 
mer, Even small plants will bloom on matured stems. 
A rich, porous soil, moderate to generous waterings 
during the summer growing season with protection 
from the midday sun in summer. 40c

smaller, easily detached branchlets, sometimes 
2-3 end to end and pendent. These branch- 
lets are different with shorter spines and since 
they are easily detached probably aid in the 
distribution of the species. Technically they are 
hard to differentiate from Lemaireocereus. |

dean valley and Mr. Akers found another one 
near Lima.

BORZICACTUS 
A small genus found from north central Peru 
to Ecuador. Britton G&G Rose placed within it 
plants since removed to other genera. Since 
the type species has a ring of hair in the tube 
and the others from the same _ geographical 
area and obviously closely related also have 
this ring it is proposed to include in the genus 
only those having this ring. Many plants have 
been named and figured from Ambato to north- 
ern Ecuador. So far as my observations go these 
cannot be substantiated for such variations can 
be found in every colony | visited in this great 
area. 
Long spines, short spines, slender and stout, 
included and exserted stamens are all inter- 
mixed. In north central Peru Mr.- Akers found 
a new species and also B. Fieldianus. Two other 
new plants have heavily tubercled ribs, tubular 
flowers with expanded limb and lack the hair 
ring.
