Kaumana Caves State Park is a small park west of Hilo. Besides the usual park facilities, the main attraction is the caves. The caves are actually a lava tube, created by a flow from Mauna Loa in 1881. They’re accessed through the large opening where a section of the tube collapsed, so the two caves are at opposite ends of this opening.
My understanding is that the caves go on for quite a way, but one is not supposed to go much beyond the entrances because it is, officially, private property after that. It’s also very dark and claustrophobic, so that was enough for me.
The photos show – Above: A view from mouth of the southern cave; Middle: The staircase down to the caves; Below: Foliage that’s grown in the open portion of the tube. The cave entrances are the dark areas at the edge of these photos.




I live in a pretty green area of the Big Island, but I always enjoy a visit to the much wetter east side. The extra rain allows the tropical foliage to run amok. Trees and shrubs compete for space and light, and vines run everywhere – along the ground and up tree trunks. It’s a riot of many shades of green and leaves of every size, from tiny ground covers to giant bananas to the distinctive leaves of a monstera deliciosa surrounding its flower (below).





This bryophyllum is probably bryophyllum x houghtonii, but there are several similar looking varieties of bryophyllum. Their common names are telling, however. Bryophyllum x houghtonii is known as ‘hybrid mother-of-millions.’ Common names for other bryophyllums include ‘mother-of-millions,’ ‘prolific mother-of-millions,’ and ‘mother-of-thousands.’
This spathoglottis orchid is probably spathoglottis picata, though it could be spathoglottis kimballiana. This one was at Hawaii Tropical Botanical Garden, which lists the kimballiana but not the picata in their plant database. However, that database doesn’t list all their plants, so it’s not conclusive. The closest images I found online looked more like the spathoglottis picata.
